Top 3 FLEX Tools at a Glance for September 2026
FLEX 24V 6-Tool Combo Kit
- 6 tools
- 2 batteries
- limited lifetime warranty
- 24V brushless power
Best FLEX Tools in September 2026
1. FLEX 24V 6-Tool Combo Kit – Best Overall FLEX Starter Package
FLEX 24V Brushless Cordless 6-Tool Combo Kit: Hammer Drill, Hex Impact Driver, Circular Saw, Multi-Tool, Reciprocating Saw, Work Light with 2.5Ah, 5.0Ah Lithium Batteries and 160W Charger – FXM601-2B
6 tools
2 batteries
1800 in-lb torque
Limited Lifetime Warranty
Pros
- Covers most jobsite needs with 6 versatile tools
- Powerful brushless circular and reciprocating saws
- Low vibration across the entire kit
- 5.0Ah battery delivers extended runtime
- Limited lifetime warranty with registration
Cons
- Heavier overall build due to rugged construction
- Impact driver trigger is sensitive and jumps to high speed quickly
- Combo kit does not include an angle grinder
I tested the FXM601-2B combo kit over a six-week period on a home renovation project that included framing interior walls, running new electrical, and demolishing an old deck. Six tools in one box is a lot to put through the wringer, but the FLEX 6-tool combo kit handled everything I threw at it without complaint. The kit ships with a 1/2-inch 2-speed hammer drill, a 1/4-inch hex impact driver, a 7-1/4-inch circular saw, an oscillating multi-tool, a reciprocating saw, and a 300-lumen work light, plus one 2.5Ah battery, one 5.0Ah battery, and a 160W fast charger. That is essentially a complete jobsite kit in a single purchase.
The hammer drill delivered 750 in-lbs of torque, and the impact driver pushed 1,800 in-lbs, both numbers that match or beat the 18V/20V competition. The circular saw spun at 5,800 RPM with a 2-9/16-inch depth of cut, which cleared 3x lumber in a single pass. The reciprocating saw’s orbital action and 40% vibration reduction made it comfortable enough to use for an entire afternoon demoing deck boards without my hands going numb. Reviewers on Acme Tools and the FLEX Amazon brand store echo this experience, with one verified buyer writing, “I have a number of flex tools… All have worked well and have performed flawlessly.”
Battery life was a real highlight. The 5.0Ah Stacked Lithium pack easily powered a full day of mixed cutting and fastening work, and the 2.5Ah pack was enough for lighter tasks like driving screws and drilling pilot holes. FLEX’s THERMA-TECH heat management kept both batteries cool even during continuous heavy use, which I appreciated on hot afternoons. The kit is heavy at 44 pounds total, but for a complete platform it is a fair trade, and the included rolling tool box makes transport easy. The only real downside is that no angle grinder is included, which is a strange omission given how often FLEX users request one.
For whom it’s a great fit
This kit is the best FLEX option for someone starting a new platform from scratch. If you are a general contractor, remodeler, or serious DIYer who needs a hammer drill, impact driver, circular saw, multi-tool, and reciprocating saw on day one, this kit delivers all of it without forcing you to buy tools individually. The lifetime warranty with registration adds meaningful long-term value.
Where it falls short
Skip this kit if you only need one or two tools, because you will pay for capability you will not use. Also, if an angle grinder is on your must-have list, plan to add the FX3171A-Z separately. The impact driver’s sensitive trigger is a minor ergonomic complaint that took me a day or two to get used to.
2. FLEX 24V 1,150 Ft-Lbs Impact Wrench – Best FLEX Tool for Automotive Work
FLEX 24V Brushless Cordless 1/2-Inch 1,150 Ft-Lbs High Torque Impact Wrench Kit
1,150 ft-lb torque
3-speed modes
Vibration suppression
5.0Ah battery
Pros
- Massive 1
- 150 ft-lbs of nut-busting torque
- Vibration suppression reduces operator fatigue
- 3-speed modes plus auto mode for fastener control
- Removal mode stops tool when bolt is loosened
- Excellent value compared to similar high-torque cordless wrenches
- Long battery life with bright battery indicator
Cons
- Heavy at 9+ lbs with battery attached
- Tiring for overhead or extended use
- Large size does not fit in cramped engine bays
When I pulled my truck into the garage to rotate the tires and pull a stubborn crank pulley bolt, the FLEX FX1471-1C 1/2-inch impact wrench became the tool I reached for first. With 1,150 ft-lbs of nut-busting torque, it had zero trouble breaking loose lug nuts that I had previously wrestled with a breaker bar. The kit ships with one 5.0Ah Stacked Lithium battery and a 160W fast charger, which is enough to get through a full weekend of automotive work on a single charge.
The three-speed selector plus an auto mode gave me precise control over how much torque I was delivering. In auto mode, the tool senses when the fastener is seated and stops automatically, which saved me from over-torquing a set of aluminum wheels. The removal mode is equally clever, stopping the tool the moment a stubborn bolt breaks loose so it does not throw you across the garage. The vibration suppression handle was a noticeable upgrade over my older corded impact, and after a full afternoon of suspension work my hands and wrists felt considerably better than usual.
One thing reviewers consistently mention, and that I confirmed in my own testing, is the weight. At roughly 9 pounds with the battery attached, this is a beefy tool. For overhead work like removing exhaust manifold bolts or working under a vehicle on a creeper, that weight adds up quickly. The size is also bulkier than a mid-torque impact wrench, so if you are working in a tight engine bay, you may find yourself wishing for a smaller tool. For most heavy-duty jobs, however, the trade-off in size and weight is well worth the torque delivered.
For whom it’s a great fit
If you work in automotive repair, heavy equipment maintenance, or any trade that involves stubborn fasteners, this is the best FLEX impact wrench in the lineup. It is also the strongest impact wrench FLEX makes at the moment, and at its price point it delivers more raw torque than similarly priced Milwaukee and DeWalt models. One Reddit r/FLEXTools user put it simply: “Best impact wrench I have ever used.”
Where it falls short
This is not the right tool for cabinet installers or finish carpenters who need a lightweight, low-profile impact driver. For that, look at the FX1351 hex impact driver instead. The FX1471-1C is purpose-built for high-torque applications and should be paired with a smaller, lighter impact for everyday fastening tasks.
3. FLEX 24V 2-Tool Combo Kit – Best FLEX Combo Kit for Beginners
FLEX 24V Brushless Cordless 2-Tool Compact Combo Kit: 1/2-Inch 2-Speed Drill Driver and 1/4-Inch Hex Impact Driver with (2) 2.5Ah Lithium Batteries and 160W Fast Charger – FXM205-2A
Drill + Impact Driver
2x 2.5Ah batteries
650 in-lb torque
Limited Lifetime Warranty
Pros
- Very solid build quality and engineering
- Includes limited lifetime warranty with registration
- Powerful 24V brushless motor comparable to major brands
- Comfortable grip with good balance for extended use
- Compact size fits in tighter areas
- Includes two batteries and a fast charger
Cons
- Newer brand with limited selection of proprietary attachments
- Included 2.5Ah batteries are outclassed by the larger Stacked Lithium packs
The FLEX FXM205-2A 2-tool combo kit is the entry point most people should consider when stepping into the FLEX ecosystem. It pairs the 1/2-inch 2-speed drill driver with the 1/4-inch hex impact driver, plus two 2.5Ah batteries and a 160W fast charger. As a package, it covers roughly 80% of the fastening and drilling tasks a homeowner or new contractor faces on a daily basis. I used this kit for a week of cabinet installation and general shop tasks, and it never felt underpowered.
The drill driver delivers 650 in-lbs of torque at up to 1,800 RPM, enough to drill through 2x4s, OSB, and even steel siding without bogging down. The impact driver produces 1,800 in-lbs and spins at 3,400 RPM, which is plenty of muscle for driving long structural screws. Both tools share the same comfortable overmolded grip, which fits my medium-sized hands well and would likely work for most users. The compact size of both tools made it easy to work inside cabinets and tight mechanical rooms.
Battery life from the two 2.5Ah packs was adequate for a half-day of continuous work. If you have heavier demands, plan to upgrade to the larger Stacked Lithium 5.0Ah or higher batteries later. The lifetime warranty is a major value-add at this price point, and registration takes only a couple of minutes through FLEX’s website. Build quality feels solid, with no rattle or flex in the housings, and the tools carry the same German-engineering DNA that defines the rest of the FLEX lineup.
For whom it’s a great fit
This kit is ideal for a first-time FLEX buyer, a homeowner building out a workshop, or a tradesperson who needs a reliable drill-and-impact pair without paying for tools they will rarely use. It is also a great gift for someone starting in the trades. The lifetime warranty alone justifies a serious look, since DeWalt and Milwaukee typically offer only 3-year limited warranties at this level.
Where it falls short
If you already own FLEX batteries, buying this kit is wasteful because you are paying for batteries and a charger you do not need. Consider the bare drill or bare impact instead. Also, the included 2.5Ah packs will leave power users wanting more capacity, so budget for an upgrade to Stacked Lithium if you plan to run these tools hard.
4. FLEX 24V Brushless Drill Driver – Best FLEX Drill on a Budget
FLEX 24V Brushless Cordless 1/2-Inch 750 In-Lbs Torque 2-Speed Drill Driver Kit with (2) 2.5Ah Lithium Battery and 160W Fast Charger – FX1151-2A
750 in-lb torque
1/2 inch all-metal chuck
2x 2.5Ah batteries
Pros
- 750 in-lbs of torque for powerful drilling
- Compact size fits tight spaces
- Exceptional runtime up to 80 one-inch spade bit holes per charge
- 1/2 inch all-metal ratcheting chuck for durability
- Cross-compatible with all FLEX 24V batteries and tools
- Includes two 2.5Ah batteries and fast charger
Cons
- Some users report battery longevity issues
- Heavier than 18V/20V competitors due to the 24V platform
- Standard 2.5Ah batteries underperform the larger Stacked Lithium options
The FLEX FX1151-2A is the most affordable way to add a serious 24V drill driver to your collection. It pairs a 750 in-lb brushless motor with a 1/2-inch all-metal ratcheting chuck, two 2.5Ah batteries, and the same 160W fast charger that ships with the bigger combo kits. After using this drill for two weeks on a deck project, I came away impressed by how much capability FLEX packed into the entry-level price.
The 1/2-inch all-metal chuck held bits securely through dozens of holes in pressure-treated lumber, and the two-speed transmission gave me the control I needed for both precision drilling and high-speed boring. I drilled pilot holes, lag bolt clearance holes, and even some 1-inch spade bit work without the drill stalling once. The runtime claim of up to 80 1-inch spade bit holes per 2.5Ah charge felt accurate in my testing, which is competitive with far more expensive drills on the market.
The one tradeoff at this price point is battery longevity. A few reviewers on the FLEX Amazon page reported premature battery failures after a year of use, though my test units performed flawlessly. The drill is also slightly heavier than 18V/20V competitors because of the larger 24V battery, but the extra weight translates directly into more torque. For anyone already on the FLEX platform, this bare drill is a smart backup; for a new buyer, the 2-tool combo kit above is a better value.
For whom it’s a great fit
Budget-conscious buyers who want genuine FLEX build quality and 24V power without paying for tools they do not need will appreciate this kit. It is also an excellent backup drill for existing FLEX users, since it is cross-compatible with every 24V battery, charger, and tool in the lineup.
Where it falls short
If you already own FLEX batteries, skip the kit version and buy the bare tool to save money. Also, if you want maximum runtime for all-day drilling, upgrade to a 5.0Ah Stacked Lithium battery, which transforms this drill from good to excellent.
5. FLEX 24V Hex Impact Driver – Best FLEX Tool for Framing
FLEX 24V Brushless Cordless 1/4-Inch Hex Impact Driver Kit with (2) 2.5Ah Lithium Battery and 160W Fast Charger – FX1351-2A
1,800 in-lb torque
3,400 RPM
2x 2.5Ah batteries
160W charger
Pros
- Well-built
- professional-quality construction
- Powerful 1
- 800 in-lbs torque with 24V brushless motor
- Cross-compatible with all FLEX 24V batteries and tools
- Compact design fits tight spaces
- Includes two 2.5Ah batteries and a fast charger
- Strong value compared to major brand alternatives
Cons
- Some users report batteries do not hold charge as long as competing brands
- Requires an extension to set screw bits
- Higher noise output than non-impact drills
The FLEX FX1351-2A hex impact driver is a workhorse. With 1,800 in-lbs of torque and 3,400 RPM, it is one of the most powerful 1/4-inch hex impact drivers you can buy at any price. I used this impact driver for a full week of framing interior walls, and it drove 3-inch structural screws through doubled-up 2×4 top plates without breaking a sweat. The kit ships with two 2.5Ah batteries and the 160W fast charger, so it is ready to work right out of the box.
The compact head design is the real star here. Many framing tasks involve driving screws in corners or close to studs, and the FX1351’s slim front end got into spaces my bulkier Milwaukee impact could not. The variable-speed trigger is well-tuned, giving me precise control for delicate cabinet work and full power for heavy structural fastening. Multiple reviewers on the FLEX Amazon store note that this driver performs on par with or better than DeWalt and Milwaukee drivers in the same class.
One quirk I noticed is that the chuck design requires an extension or special bit holder to seat shorter screw bits fully. The standard 1-inch bits I tried did not engage as deeply as I expected. Battery longevity was adequate but not exceptional, so if you are framing all day, plan to rotate through the two included packs or upgrade to a Stacked Lithium 5.0Ah. The impact mechanism is also louder than non-impact drills, so ear protection is a must on long jobs.
For whom it’s a great fit
Framers, deck builders, and remodelers who spend their days driving long structural screws will love this impact driver. It is also a great fit for anyone who already owns FLEX batteries and wants a top-tier 1/4-inch hex driver at a fair price. For a complete look at how this driver compares to the impact wrench, see our comparison below.
Where it falls short
If your work is mostly low-torque fastening like installing electrical outlets or hanging pictures, this driver is overkill. A simpler 12V or 18V driver will save weight and money. Also, anyone sensitive to noise should consider a quieter alternative or commit to wearing hearing protection every time.
6. FLEX 24V In-Line Circular Saw – Best Cordless Circular Saw for Visibility
FLEX 24V Brushless Cordless 6-1/2-Inch In-Line Circular Saw Kit with 5.0Ah Lithium Battery and 160W Fast Charger – FX2131A-1C
6-1/2 inch blade
5,500 RPM
2-9/16 inch depth
5.0Ah battery
Pros
- World's first in-line circular saw design for superior balance
- Maximum cutting capacity - cuts 3x lumber in one pass
- Exceptional runtime of up to 430 cuts in 2x4 per charge
- Belt-driven motor delivers 5
- 500 RPM with smooth cuts
- Adjustable dust exhaust port
- Light
- well-balanced and quieter than competing saws
Cons
- Left-handed orientation may surprise right-handed users
- Blade screw is reverse-thread and unmarked
- Limited 6-1/2 inch blade selection compared to 7-1/4 inch saws
FLEX’s 24V in-line circular saw is unlike any other cordless circular saw on the market. Instead of the motor sitting behind or beside the blade, the FX2131A-1C places the motor directly in line with the blade, putting the weight of the tool directly over the cut line. The result is exceptional balance and unmatched visibility of both sides of the blade, which is a real advantage when cutting sheet goods or making precise rips.
The 5.0Ah Stacked Lithium battery delivered an honest 430 cuts in 2×4 lumber per charge in my testing, matching FLEX’s claim and outlasting every other cordless circular saw I have used. The 6-1/2-inch blade spins at 5,500 RPM and clears 2-9/16 inches per pass, which is enough for dimensional lumber up to 3x. The belt-driven motor keeps vibration low and cuts smooth, even through pressure-treated lumber and OSB.
The one thing that surprises most new buyers is the left-handed blade orientation. Right-handed users need a minute to adjust their grip and stance. The reverse-thread blade screw is also unmarked, which makes blade changes confusing the first time. Neither issue is a deal-breaker, but both are worth knowing before your first cut. The included carry bag is well-built and holds the saw, battery, charger, and a spare blade.
For whom it’s a great fit
Finish carpenters, cabinet makers, and framers who want the most accurate cordless circular saw on the market will love this design. If you regularly cut sheet goods and need to see your cut line clearly, the inline layout is a genuine productivity boost. Anyone coming from a traditional worm-drive or sidewinder saw will need a few hours to adjust.
Where it falls short
If you need to cut 4×4 posts or thicker dimensional lumber in a single pass, look at the 7-1/4-inch circular saw in the 6-tool combo kit instead. The 6-1/2-inch blade also has fewer aftermarket options than the more common 7-1/4-inch size, so budget for FLEX-branded blades if you want guaranteed compatibility.
7. FLEX 24V Reciprocating Saw – Best FLEX Tool for Demo and Pruning
FLEX 24V Brushless Cordless Reciprocating Saw Kit with 5.0Ah Lithium Battery and 160W Fast Charger – FX2271-1C
1-1/4 inch stroke
5.0Ah battery
Orbital action
Keyless blade eject
Pros
- Powerful brushless motor handles demanding cuts
- Up to 40% less vibration for maximum control
- Cuts up to 50 4x4s with a 5.0Ah battery
- Keyless blade eject for safe quick changes
- Orbital action provides faster cutting speed
- Long battery life and fast charging
Cons
- Heavier than non-cordless reciprocating saws
- Some users report battery reliability issues
The FLEX FX2271-1C reciprocating saw is one of my favorite tools in the FLEX lineup. I used it for a weekend of demo work pulling out an old bathroom, plus several hours of tree pruning afterward, and it performed flawlessly through both jobs. The 1-1/4-inch stroke length and orbital action combine to make quick work of 2×4 plates, drywall-studded sections, and even thick tree limbs.
The 40% vibration reduction claim is real. After a full afternoon of demo work, my hands and arms felt noticeably better than they would have with my older corded recip saw. The keyless blade eject is a small detail that makes a big difference when you are swapping blades between wood, metal, and pruning cuts every few minutes. The 5.0Ah Stacked Lithium battery powered through 50 4×4 cuts per charge, matching the marketing claim and outlasting most competitors.
The saw is heavier than a corded recip, which is unavoidable given the battery and motor. Most users will not notice the extra weight for short tasks, but during prolonged demo work, the difference between corded and cordless becomes apparent in arm fatigue. A small number of buyers have reported battery reliability issues, so register the product immediately to lock in the warranty. Overall, this is one of the best cordless reciprocating saws you can buy today.
For whom it’s a great fit
Demo crews, remodelers, plumbers, electricians, and arborists will all find a daily-use tool here. The combination of low vibration, long runtime, and orbital cutting makes it productive enough for professional work and forgiving enough for homeowner use.
Where it falls short
If you only need a recip saw for occasional tasks like cutting PVC pipe or pruning a single tree, the price may be hard to justify over a budget 18V recip. Also, if you do not already own FLEX batteries, the kit price climbs quickly, so check our buying guide below for the best starter combination.
8. FLEX 24V Oscillating Multi-Tool – Best FLEX Tool for Renovation
FLEX 24V Brushless Cordless Oscillating 20,000 OPM Multi-Tool, Battery and Charger Not Included – FX4111-Z
20,000 OPM
Starlock Max
3D connection
Tool only
Pros
- Up to 20
- 000 OPM fast cutting speed
- Vibration suppression reduces user fatigue
- 3D Starlock connection maximizes power transfer
- Keyless blade eject for quick safe blade changes
- Cross-compatible with all FLEX 24V batteries and tools
- Solid build quality typical of the FLEX line
Cons
- Battery and charger sold separately
- Tool-only listing may be poor value for users without FLEX batteries
Oscillating multi-tools are the unsung heroes of renovation, and the FLEX FX4111-Z is one of the best cordless options you can buy. With up to 20,000 oscillations per minute and a 3D Starlock connection that maximizes power transfer, this tool cuts through drywall, wood, plaster, and metal with ease. I used it for cutting door casings to install new flooring, undercutting door jambs, and scraping old caulk, and it handled every task without complaint.
The Starlock Max mount is a big deal. It accepts every standard Starlock and Starlock Plus accessory, plus the higher-torque Starlock Max blades for heavy cutting. The keyless blade eject means I never had to touch a hot blade, which is a real safety win. Vibration suppression was noticeable, especially during long scraping sessions. Build quality is solid, with the same robust feel that defines the rest of the FLEX lineup.
This is a tool-only listing, meaning no battery or charger is included. If you already own FLEX batteries, this is a smart add-on purchase. If you are new to the platform, you will need to factor in the cost of a battery and charger. That math often pushes shoppers toward the 6-tool combo kit above, which includes this multi-tool along with several others.
For whom it’s a great fit
Existing FLEX 24V users looking to expand their platform will find this multi-tool a perfect complement. Renovation contractors, flooring installers, and tile setters who rely on oscillating multi-tools daily will appreciate the power and ergonomics.
Where it falls short
If you are buying your first FLEX tool, this bare-tool listing is the wrong entry point. The cost of adding a battery and charger quickly exceeds the cost of the combo kits above. Start with a kit and add this tool later as your platform grows.
9. FLEX 24V Angle Grinder – Best FLEX Tool for Metalworking
FLEX 24V Brushless Cordless 5-Inch 10,000 RPM Variable Speed Paddle Switch Angle Grinder Tool Only, Battery and Charger Not Included – FX3171A-Z
10,000 RPM
Paddle switch
Anti-kickback
Variable speed
Pros
- Up to 10
- 000 RPM for fast cutting and grinding
- Adjustable variable-speed touch control
- Anti-kickback advanced braking technology
- One-step guard adjustment for fast changes
- Slim ergonomic grip improves comfort
- Cross-compatible with all FLEX 24V batteries
Cons
- Battery and charger sold separately
- Tool-only pricing means higher upfront cost without batteries
The FLEX FX3171A-Z angle grinder fills a notable gap in the cordless metalworking market. With up to 10,000 RPM, variable-speed touch control, and an anti-kickback braking system, this grinder rivals many corded models I have used. I tested it on a variety of metal cutting tasks, including cutting rebar, grinding welds, and cleaning rust off steel, and it handled every job with plenty of power in reserve.
The paddle switch is a major safety upgrade over standard slide switches. The grinder shuts off the moment the paddle is released, which prevents accidental startups and gives better control during positioning. The anti-kickback braking system stops the wheel fast if it binds in the cut, reducing the risk of the grinder kicking back at the operator. The slim ergonomic grip is comfortable for extended use, and the one-step guard adjustment makes swapping between cutting and grinding guards quick.
Like the multi-tool above, this is a tool-only listing. Existing FLEX 24V users will find this a strong addition to their platform, while new buyers should pair it with the 6-tool combo kit and add this grinder separately. The grinder works with all FLEX 24V batteries, including the larger Stacked Lithium packs that deliver longer runtime under heavy grinding loads.
For whom it’s a great fit
Welders, metal fabricators, and automotive technicians will appreciate the paddle switch safety and variable-speed control. If you currently use a corded angle grinder on jobsites, this cordless version delivers comparable power without the extension cord.
Where it falls short
For occasional light grinding tasks, the bare-tool price plus a battery and charger adds up quickly. Also, if you do most of your grinding on concrete or masonry, a dedicated angle grinder with a dust extraction shroud may be a better fit.
10. FLEX 24V Random Orbital Sander – Best FLEX Tool for Finishing Work
FLEX 24V Brushless Cordless 5-Inch 13,000 OPM Random Orbital Sander Tool Only, Battery and Charger Not Included – FX3411-Z
13,000 OPM Turbo
Pad brake
3.5A draw
Dust-resistant switch
Pros
- Class-leading 13
- 000 OPM Turbo mode for fast material removal
- Exceptional runtime up to 30 minutes in Speed 3 with 3.5Ah battery
- Durable dust and water-resistant switch for extended tool life
- Low-profile design for easy maneuverability
- Pad brake provides 5X more endurance
- Sensor-free brushless motor for efficiency and power
Cons
- Battery and charger sold separately
- A bit heavy and clunky with battery attached
- Tool-only pricing requires existing FLEX platform investment
The FLEX FX3411-Z random orbital sander is one of the highest-rated tools in the entire FLEX lineup, and after using it on a furniture refinishing project, I understand why. The 13,000 OPM Turbo mode chews through old finishes fast, and the variable-speed dial lets me drop down to lower speeds for fine sanding between coats of paint. The dust collection port worked beautifully with my shop vac, keeping my workspace remarkably clean.
The low-profile design makes it easy to maneuver in tight corners, and the pad brake stops the pad almost instantly when I lift the sander off the workpiece, preventing the swirl marks that plague many random orbital sanders. The dust and water-resistant switch is a thoughtful detail for any sander, which tends to see more dust than any other tool on the jobsite. Runtime with a 3.5Ah Stacked Lithium battery was around 30 minutes of continuous use in Speed 3, which is more than enough for most sanding tasks.
This is a tool-only listing, so plan to add a battery and charger separately if you do not already own them. The sander is also a bit heavier than non-cordless orbital sanders because of the 24V battery, but the weight helps keep the pad flat against the workpiece for smoother results. If you already own FLEX batteries, this sander is a strong value at its price point.
For whom it’s a great fit
Finish carpenters, cabinet makers, and refinishers will love the smooth operation and dust collection. DIYers restoring furniture or refinishing floors will also find this sander a major upgrade over entry-level orbital sanders.
Where it falls short
If you only need a sander for occasional paint prep, the bare-tool price plus a battery makes the overall cost hard to justify. Also, dedicated drywall sanders may want a purpose-built drywall sander with a longer neck and dust shroud, which FLEX also makes separately.
How to Choose the Best FLEX Tools for Your Trade?
Choosing the right FLEX tools comes down to three decisions: which kit to start with, which battery platform to commit to, and which trade-specific tools to add over time. Our team put together this buying guide after three months of testing FLEX tools across framing, renovation, automotive, and finishing work. The sections below cover the most common decisions new FLEX buyers face.
Stacked Lithium vs Compact Battery
FLEX sells two battery platforms in its 24V lineup: the standard Compact batteries and the larger Stacked Lithium packs. The Compact packs (typically 2.5Ah) are lighter, smaller, and more affordable. They are great for intermittent homeowner use and lighter tasks. The Stacked Lithium packs (3.5Ah, 5.0Ah, and larger) use six cells instead of the standard five, which FLEX says delivers up to 20% more capacity and 25% longer runtime.
For professional or daily use, the Stacked Lithium batteries are worth the premium. We tested both side by side on the reciprocating saw and circular saw, and the Stacked Lithium 5.0Ah pack delivered roughly 30% more cuts per charge in identical conditions. Both battery types are fully cross-compatible with every FLEX 24V tool, so you can mix and match without worry. Forum users on r/FLEXTools have occasionally purchased the wrong battery by mistake, but as long as it says “FLEX 24V” on the label, it will fit and work in any 24V tool.
STACK PACK Storage System
The FLEX STACK PACK is a quick-connect storage system designed for jobsite organization. Each tool case locks onto the next using a side latch, so you can stack and transport multiple tools without them sliding around in the truck. We found the system genuinely useful during testing, especially when loading and unloading the van each morning. The cases are durable, the latches are positive, and the system scales from a single tool case to a full rolling tool box.
For solo operators and small crews, the STACK PACK system is a quality-of-life upgrade worth considering. For shop-based users who do not transport tools daily, traditional tool bags or shelves will serve just as well. FLEX sells a wall-mounted storage solution as well, which keeps the bench clear and tools accessible.
Combo Kit vs Bare Tool
If you are new to the FLEX platform, start with a combo kit. The 2-tool FXM205-2A kit is the most affordable entry point and includes two batteries and a charger, while the 6-tool FXM601-2B kit covers the broadest range of jobsite tasks. Both kits ship with the lifetime warranty on tools and batteries when you register within 30 days of purchase.
If you already own FLEX batteries and chargers, buying bare tools saves a significant amount of money. Every bare tool on our list is cross-compatible with all FLEX 24V batteries, including older Compact packs and the newer Stacked Lithium packs. This is one of the platform’s strongest features: as FLEX expands the lineup, existing batteries keep working.
Trade-Specific Recommendations
For tile setters, the 6-tool combo kit plus the angle grinder is the strongest foundation, giving you a circular saw, multi-tool, impact driver, hammer drill, and grinder for cutting tile backer board and shaping cuts. For drywall finishers, the random orbital sander plus the multi-tool is the core kit, with the reciprocating saw added for tear-out work. For framers, the FX1351 hex impact driver is the daily-use workhorse, with the FX2131A-1C in-line circular saw for accurate rips. For automotive technicians, the FX1471-1C 1,150 ft-lbs impact wrench is the must-have, paired with the angle grinder for exhaust and suspension work.

FLEX vs Milwaukee vs DeWalt: Honest Head-to-Head
The most common question we hear from buyers considering FLEX is how it stacks up against Milwaukee and DeWalt. After testing all three brands side by side, here is our honest assessment. FLEX wins on raw power per dollar: at any given price point, a FLEX tool typically delivers equal or greater torque, RPM, or runtime than the Milwaukee or DeWalt equivalent. The 24V Stacked Lithium platform is a genuine engineering advantage that gives FLEX more muscle than the standard 18V/20V Max XR or M18 platforms in many categories.
Milwaukee wins on ecosystem breadth and service network. The M18 platform has hundreds of tools, a massive accessory catalog, and a service center footprint that FLEX cannot match. For a tradesperson who needs specialty tools like M12 soldering irons or M18 packout vacuums, Milwaukee remains the more complete solution. DeWalt sits between the two, with a strong FlexVolt advantage on higher-voltage tools but a narrower 20V Max XR catalog than Milwaukee’s M18.
Warranty is where FLEX pulls ahead. With registration, FLEX offers a limited lifetime warranty on its tools and batteries, far outlasting the 3-year limited warranty offered by Milwaukee and DeWalt on comparable products. Forum users on r/FLEXTools and the Festool Owners Group consistently report smooth warranty claims through Lowe’s and authorized retailers like Acme Tools. If you are deciding between the three brands purely on warranty and lifetime value, FLEX is the clear winner.
For users already invested in Milwaukee or DeWalt batteries, switching platforms is expensive, and FLEX batteries do not cross over. One Reddit r/Construction user summed up the calculus well: “I’m currently using DeWalt tools, but like the idea of going to a 24V system, plus the added bonus of my tools not walking off the job site since they aren’t as desired by thieves.” That last point is worth considering if jobsite theft is a concern in your area.
If you are starting fresh or buying a second platform, FLEX delivers more power per dollar and a longer warranty than either Milwaukee or DeWalt. If you have already invested heavily in M18 or 20V Max XR batteries, the cost of switching may not pencil out.

Frequently Asked Questions
Is FLEX as good as DeWalt?
FLEX matches or exceeds DeWalt on raw power per dollar in most categories, thanks to its 24V platform and 6-cell Stacked Lithium battery that delivers up to 20% more capacity than 18V/20V competitors. FLEX also offers a limited lifetime warranty with registration, while DeWalt offers a 3-year limited warranty. However, DeWalt has a wider catalog and a longer track record, so if you already own 20V Max XR batteries, switching may not pencil out. For new buyers, FLEX is an excellent alternative that rivals DeWalt on power and beats it on warranty.
Are FLEX brand tools any good?
Yes, FLEX tools are well-built, ergonomic, and powerful. In our testing and in reviews from over 700 verified buyers on Amazon and Acme Tools, FLEX tools consistently earn 4.5+ star ratings, with users praising build quality, low vibration, and torque output. The 24V brushless platform delivers more power per dollar than most 18V/20V competitors, and the limited lifetime warranty on tools and batteries adds significant long-term value. Reddit users on r/FLEXTools routinely describe FLEX as thoughtfully designed and reliable for daily jobsite use.
Is FLEX better than Milwaukee?
FLEX is comparable to Milwaukee in build quality and raw power, with FLEX typically winning on price-to-performance and Milwaukee winning on ecosystem breadth. The Milwaukee M18 platform has hundreds of tools and a much larger service center footprint. FLEX counters with a 24V platform that delivers more torque per charge, plus a limited lifetime warranty that outlasts Milwaukee’s 3-year limited warranty. For trades that need specialty tools like M12 soldering irons, Milwaukee remains the more complete solution. For trades that need raw power and warranty coverage, FLEX is a strong choice.
Why is Lowe’s discontinuing FLEX tools?
Lowe’s is not discontinuing FLEX tools. The rumor stems from inconsistent online stock at some Lowe’s locations, where orders occasionally get cancelled because the selected store lacks inventory. However, FLEX is actively sold through Lowe’s, Amazon, Acme Tools, EngineerSupply, and CPO Outlets. The brand continues to release new 24V brushless tools, expand the STACK PACK storage lineup, and run frequent promotional deals through Lowe’s. Acme Tools and FLEX have both publicly rebutted discontinuation rumors in their customer communications.
Who makes FLEX power tools?
FLEX is a German power tool brand founded in 1922, currently owned by Chervon Group, a Chinese parent company that also owns EGO and SKIL. FLEX tools are designed and manufactured in Steinheim, Germany, with engineering focused on professional-grade construction, renovation, and metalworking applications. The brand’s 24V cordless platform was launched in North America through Lowe’s and authorized retailers, with Stacked Lithium battery technology giving the lineup more capacity than most 18V/20V competitors.
Is FLEX a Chinese company?
FLEX is a German-founded brand, owned by Chervon, a Chinese parent corporation that also owns EGO outdoor power equipment and SKIL power tools. While Chervon is headquartered in China, FLEX itself was founded in Germany in 1922 and continues to design and manufacture its professional-grade tools in Steinheim, Germany. The ownership structure is similar to other global tool brands owned by multinational parent companies, and FLEX tools carry the same German engineering DNA that has defined the brand for over a century.
