Which Oscillating Multi-Tool Is Best for DIY Renovation in 2026?#

What is the best oscillating multi-tool for DIY renovation in 2026?

The best oscillating multi-tool for DIY renovation in 2026 is the Milwaukee 2836-20 M18 FUEL Brushless at $187.99, because its 3.5° oscillation angle - the widest in its class - removes material 18–22% faster than budget competitors in timed tests, and its REDLINK PLUS intelligence prevents motor overload during sustained grout removal or subfloor cutting. Tool Guyd's long-term testing found no detectable power degradation after 200+ hours of use. For value buyers, the DEWALT DCS356BR at $119.99 (renewed) delivers brushless motor performance with universal blade compatibility. The Fein Cordless MultiMaster AMM 700 Max ($599.95) is the professional choice for all-day renovation sessions requiring maximum vibration dampening and the StarlockMax accessory ecosystem.

An oscillating multi-tool is arguably the single most versatile power tool a renovator can own. One tool undercuts door casings for laminate flooring, removes tile grout, trims PVC pipe in tight cabinet spaces, cuts drywall access holes, and scrapes adhesive off concrete subfloors - tasks that would otherwise require four or five separate tools ^[4]. After evaluating the full 2026 lineup from Milwaukee, DEWALT, Fein, Makita, Bosch, and Dremel, we identified six models covering every price point from $120 to $599.

Brushless cordless models have largely closed the power gap with corded tools for most DIY renovation tasks ^[2]. The key differentiators in 2026 are oscillation angle (3.5° spans cut 15–20% faster than 3.0°–3.2° competitors), blade attachment systems (Starlock vs. universal clamp), and battery ecosystem compatibility. The Milwaukee M18 FUEL at $187.99 leads on raw performance; the Dremel MM20V-01 at $120.40 leads on total out-of-box value by including a battery in the kit.

We evaluated each tool on cutting speed in 2x4 pine, grout removal from a simulated 50-square-foot tile floor, overhead-use fatigue, blade change time, and accessory ecosystem breadth. Every model was assessed against direct competitors in its price tier. Buying a tool-only model only makes sense if you already own matching batteries - factor in $50–$100 per battery pack for any tool-only purchase.

At 3.1 lbs with battery, heavier than sub-compact alternatives for overhead work

value8.0

design9.0

performance10.0

The Pitch

Milwaukee designed the 2836-20 M18 FUEL around three headline specs: 3.5° oscillation angle (versus 3.0°–3.2° on most competitors), REDLINK PLUS overload protection that monitors motor temperature and load in real time, and an Auto-Load variable speed system that begins each cut slowly for precision and ramps to full speed once the blade is under load. The 180° LED ring is the only light design in the class that eliminates all directional shadows.

The Experience

The 3.5° oscillation angle is the single most impactful functional differentiator in real renovation use. Pro Tool Reviews timed pine 2x4 flush cuts across 12 oscillating models and found the Milwaukee completed cuts 18–22% faster than budget corded competitors ^[2]. The Auto-Load feature is particularly useful for undercutting door casings - start the plunge precisely at low speed, and the tool manages the rest. Tool Guyd's long-term testing found no detectable power degradation after 200+ hours of continuous renovation use ^[1].

The Catch

At $187.99 tool-only, this is an expensive entry point for anyone not already in the M18 platform. Milwaukee's branded blade pricing runs 10–15% higher than generic Starlock-compatible alternatives, though third-party Starlock blades work correctly. The weight - 3.1 lbs with a standard M18 battery - is noticeable during overhead casing cuts that require 20+ minutes of continuous upward reach.

Before you buy

Skip this if you don't own M18 batteries - the total investment climbs to $240–$290 with a starter battery. Budget buyers without an existing platform should also consider the Dremel MM20V-01 kit which includes a battery at $120.40.

performance8.0

The Pitch

DEWALT positioned the DCS356B as their most versatile cordless oscillating tool, featuring three preset speed settings rather than a continuous dial, and a universal blade clamp that accepts both modern Starlock and older hex-shank systems. Popular Mechanics editors named it their top pick for blade compatibility, noting the universal clamp accepts both blade types without any adapter - saving users $10–$15 per blade set versus tools requiring a separate adapter accessory ^[3].

The Experience

The 3-speed preset system (rather than a continuous dial) is a genuine workflow advantage: low (8,000 OPM) for delicate PVC trimming and thin trim work, high (18,000 OPM) for aggressive grout removal, middle for everything between. The Dual-Grip trigger provides control from both the top-grip and barrel-grip positions - a real benefit during a four-hour bathroom tile session where hand position shifts frequently. The brushless motor delivers consistent torque without the heat buildup that shortens brushed motor tool life over a renovation career.

The Catch

The renewed status is the only genuine hesitation. DEWALT's certified renewed program tests returns to original working condition, but a hard-working renovator may reasonably prefer new. At $119.99 versus $129–$159 retail for a new unit, the $10–$40 savings are real - roughly equivalent to a quality blade set. Availability is currently limited to 15 units, so buyers should act quickly if this is their target.

Before you buy

The renewed designation means returned, inspected, and recertified - not used. Buyers without DEWALT batteries still need to budget $50–$80 for a 20V MAX battery pack. The savings versus a new unit ($129–$159 retail) are meaningful: roughly enough for a quality blade kit.

Fein Cordless MultiMaster AMM 700 Max: Is $599.95 Ever Justified for a DIYer?#

Combined tool-and-4Ah-battery weight exceeds 4 lbs - heavier than sub-compact competitors

value5.0

design10.0

performance10.0

The Pitch

Fein invented the oscillating multi-tool in 1967, and the AMM 700 Max is their current cordless flagship. The kit includes a 4Ah battery, a QuickIn rapid-clamping system for sub-3-second tool-free blade changes, and full StarlockMax compatibility - the broadest professional blade selection on the market in 2026. AMPShare/Bosch 18V battery compatibility means existing Bosch cordless tool owners can use cells they already own.

The Experience

The anti-vibration system is not marketing language - it produces a physically distinct difference during extended use. After a four-hour grout removal session covering a 50-square-foot bathroom floor, the fatigue difference between the Fein and a standard cordless tool is significant. This Old House's renovation team found oscillating tools reduced grout removal time by approximately 60% versus manual grout rakes on that same floor area ^[4]. The QuickIn blade change - under 3 seconds without tools - compounds into real time savings across a job requiring 6–8 blade changes.

The Catch

The $599.95 price includes the 4Ah battery, which brings total kit cost closer to the Milwaukee kit price - but Milwaukee's performance in timed cutting tests closely matches the Fein at a significantly lower investment ^[2]. This is the right tool for contractors billing by the hour who need maximum uptime and minimum fatigue over a long career. For a homeowner renovating one bathroom, the Fein is difficult to recommend on economics. Buy it if uptime and professional blade selection matter more than the price delta.

Before you buy

If your renovation sessions run under two hours per sitting, the Fein's anti-vibration premium is less meaningful. The Milwaukee M18 FUEL or Bosch GOP18V-34N serve most weekend DIYers at a fraction of the cost. Fein's AMPShare compatibility with Bosch 18V batteries adds value for Bosch platform owners.

Makita XMT04ZB 18V LXT Sub-Compact: Best Oscillating Tool for Makita Battery Owners?#

Makita XMT04ZB 18V LXT® Lithium-Ion Sub-Compact Brushless Cordless StarlockMax® Multi-Tool

4.5$146.95

The Makita XMT04ZB is the best oscillating multi-tool for existing Makita LXT battery owners - its sub-compact body, up to 85% vibration reduction via AVT, and full StarlockMax compatibility deliver professional results at $146.95.

Check price at Amazon

What we like

Anti-Vibration Technology (AVT) reduces vibration up to 85% - exceptional for a sub-compact tool
Variable speed 10,000–20,000 OPM via control dial
Sub-compact, slim grip design ideal for overhead work and tight cabinet interior cuts
Compatible with StarlockMax, StarlockPlus, and Starlock accessories - maximum blade selection
Makita-built brushless motor delivers consistent torque across the full speed range

What we don’t

Tool-only at $146.95 requires existing Makita LXT 18V batteries ($50–$80 each)
Sub-compact motor less suited for all-day heavy demolition compared to full-size competitors
No Auto-Load feature - operator manages speed manually

value9.0

design9.0

performance8.0

The Pitch

The XMT04ZB is Makita's sub-compact LXT multi-tool - a shorter, slimmer body designed for spaces where full-size tools bind: cabinet interiors, tight corner cuts, and overhead work where a heavier tool induces arm fatigue. The AVT (Anti-Vibration Technology) system uses internal counterweights to absorb vibration at the source rather than passing it through to the operator's hand, with Makita claiming up to 85% vibration reduction versus standard construction.

The Experience

The slim grip is the defining characteristic in renovation use. During overhead door casing undercuts, the Makita's shorter nose reaches under a casing where the Milwaukee or Fein would require a shallower, less controlled entry angle. The 85% AVT vibration reduction is measurable: over a 90-minute baseboard installation session, the hand numbness common with high-OPM tools is significantly reduced. StarlockMax compatibility ensures access to professional-grade blades rather than manufacturer-exclusive accessories.

The Catch

The sub-compact motor sacrifices sustained heavy-load performance. For 30-minute tile grout removal the Makita performs well; for a four-hour subfloor demolition session, the Fein AMM 700 Max or Milwaukee M18 FUEL maintain speed under load more consistently. At $146.95 tool-only, the value depends entirely on existing LXT battery ownership. The Makita LXT ecosystem powers 300+ tools, so the battery investment is defensible for platform owners - less so for buyers starting fresh.

Before you buy

Without existing LXT batteries, the cost advantage of $146.95 tool-only narrows considerably. If starting fresh with no Makita batteries, the Milwaukee M18 FUEL delivers a larger oscillation angle and comparable vibration management at $41 more.

Bosch GOP18V-34N StarlockPlus: Does the Redesigned Handle Change Everything?#

StarlockPlus (not StarlockMax) - excludes the largest Fein-format accessories

value8.0

design9.0

performance8.0

The Pitch

The GOP18V-34N represents a significant handle redesign for Bosch's cordless oscillating line. The headline change is a 90°-rotated battery position - engineers moved the pack from an inline position to a side-mounted orientation, reducing the tool's overall profile during flat flush cuts. The StarlockPlus 3-D blade interface grips accessories in three dimensions rather than two, transferring more torque and enabling blade changes approximately 8x faster than the previous-generation Bosch OIS system.

The Experience

The handle redesign matters most during floor-to-wall flush cuts - undercutting door casings for laminate or hardwood installation, where the battery position on older tools interfered with maintaining a true flat cut angle. The 3-D Starlock blade grip is noticeably more secure than two-dimensional interfaces; blades do not chatter or shift under heavy grout removal loads. Performance in pine 2x4 flush cuts is on par with comparable 18V brushless competitors at similar OPM settings.

The Catch

At $179.00 bare-tool, the Bosch GOP18V-34N sits just $8 below the Milwaukee M18 FUEL - a gap too narrow to be the primary purchase driver. The Milwaukee delivers a wider 3.5° oscillation angle and the broader M18 battery ecosystem for eight dollars more. The Bosch makes sense as a platform addition for existing Bosch 18V or Fein AMPShare battery owners, but as a first cordless multi-tool purchase, the Milwaukee delivers more measurable return per dollar.

Before you buy

At $179.00 bare-tool versus the Milwaukee at $187.99, the decision almost always comes down to battery ecosystem. Bosch's AMPShare system cross-compatible with Fein cordless tools adds value for users of both brands. For those starting a new battery platform, Milwaukee's superior oscillation angle and broader ecosystem make more sense.

Dremel MM20V-01 Cordless Kit: The Best Oscillating Tool That Actually Includes a Battery?#

value9.0

design7.0

performance7.0

The Pitch

The Dremel MM20V-01 is sold as a complete kit with one 20V battery included - a meaningful distinction when all competing brushless models require a separate $50–$80 battery purchase. The angled body design places the motor above and behind the blade, reducing the tool's forward profile for flush-cut access. Dremel targets the casual DIYer who needs to cut PVC under a sink, trim a baseboard, or remove grout from a bathroom floor without investing in a major battery ecosystem.

The Experience

For a first oscillating tool, the MM20V-01 handles core renovation tasks competently. Bob Vila's testing panel found budget oscillating tools capable of completing 95% of common DIY renovation cuts at less than half the cost of premium cordless models ^[5]. The angled body genuinely helps during flush cuts, and the compact front end fits inside cabinet frames where larger tools hit the side walls. Variable speed across 10,000–20,000 OPM means the tool handles both delicate PVC trimming and aggressive grout removal.

The Catch

The brushed motor is the key long-term limitation. Brushless motors in the Milwaukee, DEWALT, Makita, and Bosch models run cooler, last longer, and deliver up to 57% more runtime per charge ^[2]. For a 50-square-foot bathroom floor grout removal session, the Dremel will require more frequent battery recharges than a brushless competitor. It is the right tool for a homeowner who renovates occasionally. It is not the right tool for anyone who expects hard, regular use over multiple years.

Before you buy

The Dremel 20V platform is a closed ecosystem - battery incompatibility with major brands is a real long-term limitation. If you plan to build a full cordless tool lineup, start with Milwaukee M18, DEWALT 20V MAX, or Makita LXT instead, and buy tool-only. The Dremel makes sense only if this is your sole cordless tool.

What is the best budget oscillating multi-tool kit that includes a battery?

The best budget oscillating multi-tool kit that includes a battery is the Dremel MM20V-01 at $120.40, because it ships with a 20V battery - eliminating the $50–$80 additional purchase required by tool-only models - and covers the full 10,000–20,000 OPM variable speed range for wood, PVC, metal cutting, sanding, and grout removal. Bob Vila's testing found budget tools like this capable of completing 95% of common DIY renovation tasks. The main tradeoff is a brushed motor (shorter lifespan than brushless competitors) and a closed Dremel 20V ecosystem with no cross-compatibility with DEWALT, Milwaukee, or Makita batteries.

What Should You Actually Look For in an Oscillating Multi-Tool for Home Renovation?#

The best oscillating multi-tool for your renovation depends on four primary factors: power source, oscillation angle, blade attachment system, and battery ecosystem fit. Understanding each one prevents an expensive mismatch between the tool you buy and the jobs you actually need it for ^[1].

Corded vs. cordless: Cordless models from Milwaukee, DEWALT, Makita, and Bosch have closed the power gap for most DIY renovation tasks in 2026. Corded tools remain better only for all-day sustained work where continuous power matters over mobility.
Oscillation angle: 3.5° (Milwaukee M18 FUEL) cuts 15–20% faster than the 3.0°–3.2° standard on most competing cordless models. For heavy renovation tasks - subfloor demolition, full tile grout removal - that speed advantage compounds across a full job.
OPM range: Variable speed (10,000–20,000 OPM) is essential. Low speed protects delicate materials like thin PVC and finished trim; high speed powers through grout and hardwood efficiently.
Blade attachment system: StarlockMax offers the best blade selection and torque transfer. DEWALT's universal clamp provides the most backward compatibility with existing blade collections. Both are preferable to proprietary single-brand interfaces.
Brushless vs. brushed motor: Brushless motors run cooler, last longer, and deliver up to 57% more runtime per charge. Prioritize brushless for any sustained renovation use - the Milwaukee, DEWALT, Fein, Makita, and Bosch models all use brushless; the Dremel MM20V-01 does not.
Vibration dampening: Critical for sessions over 60 minutes. The Fein AMM 700 Max's anti-vibration system and Makita XMT04ZB's AVT (up to 85% reduction) are the class leaders. Hand fatigue during a four-hour bathroom tile job is a real productivity issue.
Battery ecosystem: Tool-only purchases require existing matching batteries ($50–$100 each). The Dremel MM20V-01 kit ($120.40) is the only model reviewed here that includes a battery. Factor total kit cost, not just tool price.
Weight and balance: Sub-3-lb tools (with battery) reduce fatigue during overhead door casing cuts and ceiling-level baseboard work. The Makita XMT04ZB's sub-compact form factor is specifically designed for this use case.
Accessory ecosystem breadth: More available blade types - plunge cut, flush cut, segmented arc, semicircle sanding, rigid scraper - expand the tool's versatility on a full renovation job site.

What oscillating tool blades do I need for a complete bathroom renovation?

For a complete bathroom renovation, you need four blade types: a carbide-grit grout removal blade for tile joint work, a bi-metal plunge cut blade for PVC pipe and drywall cutouts, a flush cut wood blade for undercutting door casings before new flooring, and a half-round sanding pad for finishing wood trim. All four types are available in Starlock or universal-fit format from Fein, Milwaukee Shockwave, or Bosch Starlock for $35–$60 as a renovation starter kit. Blade quality matters as much as tool quality - cheap blades overheat and lose their edge within a single grout removal session on a standard 50-square-foot bathroom floor.

Frequently Asked Questions About Oscillating Multi-Tools#

Frequently Asked Questions

What is an oscillating multi-tool actually used for in home renovation?

An oscillating multi-tool cuts, sands, scrapes, and grinds in spaces where no other tool fits. Core renovation uses include: undercutting door casings for laminate or hardwood flooring, removing tile grout, trimming PVC and copper pipe in tight cabinet spaces, cutting drywall access holes, scraping adhesive off concrete subfloors, and flush-cutting protruding nails or screws level with framing. This Old House's renovation team found that oscillating tools reduced bathroom tile grout removal time by approximately 60% compared to manual grout rakes on a 50-square-foot floor - making it one of the highest-impact tool investments for bathroom and kitchen remodels.

Corded vs. cordless oscillating tool - which should I buy for a bathroom remodel?

For a bathroom remodel, cordless is the better choice for most DIYers. Brushless cordless models from Milwaukee, DEWALT, Makita, and Bosch have closed the power gap with corded tools for the kinds of sustained work a bathroom remodel involves - grout removal, PVC trimming, baseboard work, and tile cutting. Corded tools remain superior only for all-day continuous use (8+ hours) where battery swapping would be disruptive, such as professional subfloor replacement across a large square footage. For a weekend renovator doing one bathroom, cordless mobility outweighs any power differential.

Are oscillating tool blades universal - will DEWALT blades fit a Milwaukee tool?

Not automatically, but compatibility is improving significantly. The Starlock and StarlockMax interface is adopted by Milwaukee, Fein, Makita, Bosch, and Festool - blades from these brands fit each other's Starlock tools. The DEWALT DCS356BR uses a universal clamp that accepts both modern Starlock and the older universal hex-shank format without any adapter. Older-style blades with a round-hole universal interface may require a $5–$10 adapter on dedicated Starlock tools. Always verify the blade's listed compatibility before purchasing, especially when mixing brands.

What's the best oscillating multi-tool under $150 for occasional DIY use?

The Dremel MM20V-01 at $120.40 is the best oscillating multi-tool under $150 for occasional use because it includes a 20V battery in the kit - eliminating the $50–$80 additional battery cost required by tool-only models. It covers the full 10,000–20,000 OPM range, handles wood, PVC, metal, grout, and sanding, and its compact front end accesses tight corners. For occasional DIY use (a few projects per year), the brushed motor limitation is not a practical issue. The DEWALT DCS356BR (Renewed) at $119.99 is also excellent if you already own DEWALT 20V MAX batteries.

What blades do I need for a complete kitchen or bathroom renovation?

Four blade types cover a complete kitchen or bathroom renovation: (1) a carbide-grit grout blade for tile joint removal, (2) a bi-metal plunge cut blade for drywall, PVC, and wood cuts, (3) a flush cut wood blade for door casing undercuts before new flooring, and (4) a half-round sanding pad with 80-grit and 120-grit sheets for trim finishing. A quality renovation blade kit from Bosch, Milwaukee, or Fein covering all four categories costs $35–$60. Avoid no-name blade sets - cheap bi-metal blades overheat and lose their cutting edge within a single grout removal session.

Can an oscillating tool cut through nails and screws embedded in wood?

Yes, with the correct blade. A bi-metal blade rated for metal cutting handles finish nails, galvanized screws, and thin-gauge metal embedded in framing or trim. Use a slow-to-medium speed setting (12,000–15,000 OPM) to avoid overheating at the metal contact point. Never use wood-only blades for nail cutting - they will chip or fracture on contact with metal. For cutting structural bolts or large-diameter hardware, a reciprocating saw is more efficient. The oscillating tool excels at precision nail cuts in tight spaces where a reciprocating saw cannot safely swing.

What is the Starlock system and do I need it?

Starlock (and StarlockMax) is a blade attachment interface developed by Fein and subsequently adopted by Milwaukee, Bosch, Makita, and Festool. It uses a three-dimensional engagement system that transfers more torque from tool to blade than the older round-hole universal interface and enables tool-free blade changes. You don't need Starlock specifically - the DEWALT DCS356BR universal clamp accepts both Starlock and legacy blades. But Starlock is the closest thing to an industry standard in 2026, and choosing a Starlock-compatible tool gives you access to the widest range of professional accessories across multiple brands.

How long do oscillating tool blades last before needing replacement?

Blade life varies dramatically by material and blade quality. A quality bi-metal blade cuts approximately 10–15 linear feet of 2x4 pine before dulling noticeably. A carbide-grit grout blade handles 20–40 linear feet of standard ceramic tile grout joints before losing efficiency. Cheap blades from no-name sets may dull within a single renovation task. Clear replacement indicators include: slower cutting with the same pressure, a burning smell, visible heat discoloration on the blade body, or chattering under load. Budget for 3–5 blade replacements per major renovation project.

What's the best oscillating tool for removing tile grout without damaging adjacent tiles?

The Milwaukee 2836-20 M18 FUEL ($187.99) is the best oscillating tool for controlled grout removal - its Auto-Load feature starts each cut at low speed for precise blade placement before ramping to removal speed, reducing the risk of blade slip onto tile faces. Use a grout-specific carbide blade (not a wood cutting blade), set initial speed to 10,000–12,000 OPM to establish the cut path, then increase to 15,000–17,000 OPM for material removal. Keep the blade strictly perpendicular to the grout joint. Practice on a low-visibility section - such as inside a vanity cabinet - before working on exposed wall tile.

Can an oscillating multi-tool cut drywall, and what blade should I use?

Yes - an oscillating tool excels at precision drywall cuts. Use a bi-metal plunge cut blade to cut electrical outlet cutouts, plumbing access holes, and repair patches without damaging the paper face on the back side of the drywall sheet. Set speed to medium (14,000–16,000 OPM). The oscillating tool creates cleaner, more accurate cutouts than a jab saw or rotary tool in tight spaces and does not generate the gypsum dust cloud that circular blades produce. It cannot replace a drywall saw for full panel cuts but is the best tool for any precision cutout under 18 inches.

Is the Milwaukee M18 FUEL oscillating tool worth the premium over budget options?

The Milwaukee 2836-20 M18 FUEL at $187.99 is worth the premium if you renovate multiple times per year and already own M18 batteries. The 3.5° oscillation angle cuts 18–22% faster than budget competitors in timed independent tests, and REDLINK PLUS intelligence protects the motor during sustained hard use over a long tool life. For a casual homeowner doing one or two renovation projects per year, the Dremel MM20V-01 at $120.40 (with battery included) or the DEWALT DCS356BR at $119.99 (renewed) deliver sufficient performance at meaningfully lower total cost.

What's the best oscillating tool for undercutting door casings for laminate flooring?

The Milwaukee 2836-20 M18 FUEL ($187.99) is the top choice for undercutting door casings - its 3.5° oscillation angle produces the fastest through-cut in pine casing material, and the Auto-Load feature starts slow for a precise plunge and ramps automatically. The Bosch GOP18V-34N ($179.00) is a strong alternative specifically because its 90°-rotated battery position reduces interference when holding the tool flat against the subfloor at the required low entry angle. Use a flush-cut wood blade for this task - not a plunge cut blade, which has a different tooth geometry.

What oscillating tool blade should I use for scraping adhesive off a concrete subfloor?

Use a rigid floor scraper blade - a wide, flat accessory designed specifically for removing thin-set mortar, vinyl tile adhesive, and mastic from concrete and plywood substrates. Set the tool to high speed (18,000–20,000 OPM) and hold the blade flat against the surface at a 10–15° angle. Carbide-grit scrapers handle hardened thin-set; standard steel scrapers work for softer vinyl adhesive. Replace blades frequently - adhesive scraping is among the most blade-dulling applications in renovation work. Plan for 2–3 blade changes per 50 square feet of adhesive removal.

What's the best cordless oscillating tool if I already own Milwaukee M18 batteries?

If you already own Milwaukee M18 batteries, the Milwaukee 2836-20 M18 FUEL Brushless at $187.99 tool-only is the clear and only answer. Your existing batteries connect immediately - no adapter, no ecosystem compromise. The M18 FUEL delivers the widest oscillation angle (3.5°) in any cordless oscillating tool tested, REDLINK PLUS overload protection, and Auto-Load variable speed. Tool Guyd's long-term testing confirmed no detectable performance degradation after 200+ hours of use. Buying any other brand means your M18 batteries are incompatible, requiring an additional $50–$100 battery purchase.
