Cordless power tools changed the jobsite, and angle grinders were slow to follow. Early battery models lacked the torque for real metalwork, leaving trade pros tied to extension cords. The current generation of brushless motors changed that conversation entirely. You’re cutting rebar on a rooftop, grinding welds in a tight corner, or smoothing a rusty trailer fender in the driveway, the right cordless grinder lets you work like the cord isn’t missed.
Below are ten battery angle grinders worth your attention, ranging from heavy-duty 18V workhorses to a compact 10.8V option for lighter trim work. Each one earns its place through a specific mix of power, ergonomics, or value.
The Choices Worth Comparing
The DGA513Z slides into the Makita 18V LXT lineup as a refined, no-nonsense grinder built around a brushless motor. Brushless motors trade carbon brushes for electronic control, which generally extends runtime and reduces heat buildup under load. The 125mm wheel capacity suits most metal-cutting and grinding discs you’ll find at a hardware supplier, and the soft-start function ramps the motor up gently instead of jerking the tool in your hand.
For welders grinding down beads or tradespeople cutting pipe on a rooftop, this grinder balances power and control in a way few rivals match. Variable speed via a control dial lets you tune the wheel speed to the material, slower for stainless to avoid bluing, faster for aggressive stock removal.
Key Advantages
- Brushless motor design supports longer runtime and motor life compared to brushed equivalents.
- Variable speed dial gives you material-specific control, useful when switching between steel and aluminum.
- Soft-start feature reduces the wrist snap common to high-torque grinder startup.
- 125mm disc compatibility covers the most common cutoff and grinding wheel formats.
Things To Consider
- Battery and charger are sold separately, a real cost consideration if you’re new to the LXT platform.
- Owners commonly report the side handle position can feel cramped for users with larger hands.
- Not ideal for anyone needing 5-inch (125mm+) capacity, this one tops out at the 125mm format.
Best Suited To
Metalworkers, welders, and fabricators already invested in the Makita 18V LXT system who want a controllable, brushless grinder for daily shop and site work.
Consider Something Else When
Shoppers starting from scratch without LXT batteries may prefer the DEWALT DCG412P2 kit, which ships with batteries and a charger included.
Where the DGA513Z leans toward a compact body, the DGA517Z steps up with a paddle switch design that many pros prefer for heavy grinding sessions. A paddle switch requires deliberate pressure across the entire switch to run, which adds a layer of safety if the tool is dropped or shifted suddenly. The body still runs the same 18V brushless platform, and the soft-start behavior carries over.
You’re spending a full day grinding welds on structural steel, the paddle format lets you relax your grip without worrying about a trigger slipping out of position. Variable speed control keeps it adaptable, and the Automatic Torque Drive technology adjusts wheel speed based on load for steadier cuts.
The Value In It
- Paddle switch design is widely favored for production grinding and reduces hand fatigue.
- Automatic Torque Drive adjusts output under load, helping maintain consistent cutting speed.
- Soft-start and variable speed dial carry over from the proven LXT grinder platform.
- Tool-free wheel changes save downtime on the jobsite.
Worth Noting
- Paddle switches are a personal preference; users accustomed to trigger-style grinders face a learning curve.
- Battery and charger sold separately, adding to the overall platform investment.
Made For
Fabricators and full-time tradespeople who spend hours grinding at a time and want a paddle switch for safer, more relaxed handling.
Look Elsewhere When
Users preferring a traditional trigger switch should consider the Makita XAG11Z instead, which offers similar brushless performance in a trigger format.
The XAG09Z is the workhorse of the Makita LXT grinder family. It accepts both 4-1/2″ and 5″ wheels, giving you flexibility for thinner cutoff discs or heavier grinding wheels, and the brushless motor delivers the kind of cutting force users previously only got from corded models. An electric brake stops the wheel quickly when the trigger releases, reducing the risk of accidental contact after power-off.
Compared to the DGA513Z reviewed earlier, this grinder trades some ergonomic refinement for raw versatility. You’re cutting thick rebar or slicing through plate steel, the extra wheel diameter and motor torque make this a natural fit.
The Practical Payoff
- Accepts both 4-1/2″ and 5″ wheels, doubling your disc options for different applications.
- Electric brake stops the wheel within seconds of trigger release, a meaningful safety upgrade.
- Automatic Speed Change technology adjusts RPM under load to maintain cutting performance.
- Brushless motor construction extends service life for daily professional use.
Trade Offs
- Battery and charger are sold separately, a barrier for users outside the LXT ecosystem.
- Slightly heavier than the smaller 125mm Makita models, which can wear you down during overhead grinding.
Who It Suits Best
Professional fabricators and serious DIYers handling heavy material removal, structural cuts, and demanding workshop sessions where wheel versatility matters.
Swap It Out When
Users prioritizing compact handling for tight overhead work should look at the Makita DGA513Z instead, which is built for smaller-scale grinding tasks.
The XAG20Z combines the larger 4-1/2″/5″ wheel capacity of the XAG09Z with the paddle switch design favored on production floors. You get the electric brake, the brushless motor, and the Automatic Speed Change technology all in one package. For anyone who’s watched a grinder kick back across a bench, the paddle switch is genuinely reassuring.
This grinder feels at home in steel fabrication shops, automotive restoration work, or anywhere the operator wants a controlled, deliberate safety switch instead of a trigger. It pairs naturally with the rest of the LXT platform if you’re already running Makita cordless tools.
What Helps Most
- Paddle switch cuts power the moment you let go, a meaningful safety upgrade over trigger styles.
- Accepts 4-1/2″ and 5″ wheels, broadening your disc options for varied work.
- Electric brake brings the wheel to a stop within roughly two seconds of release.
- Brushless motor and Automatic Speed Change combine for efficient, load-aware cutting.
Minor Gripes
- Battery and charger are not included, so the upfront cost climbs quickly for new LXT users.
- Paddle switches take adjustment if you’re used to a trigger-style grinder.
Perfect Match For
Production welders, fabrication shop workers, and safety-minded tradespeople who want paddle switch control with the cutting capacity of larger discs.
A Better Fit Elsewhere
Light-duty DIYers without frequent grinding sessions may prefer the more compact Makita DGA517Z, which costs less and handles common home tasks comfortably.
This DEWALT kit pairs a 4.5-inch paddle switch angle grinder with a 1-1/2-inch die grinder, along with a 5Ah XR battery and a fast charger. Die grinders handle precision work in tight spaces, porting, deburring, and finishing tasks that a full-size grinder can’t reach. Buying them as a kit is where the value shows up: a single battery and charger power both tools.
Workshop owners and pros already leaning toward the 20V MAX platform get an entry point that ships ready to work. The angle grinder includes a kickback brake that stops the wheel in two seconds or less, and a two-stage trigger that requires deliberate action to start.
Notable Upsides
- Two-tool combo covers both heavy grinding and fine detail work in one purchase.
- Includes a 5Ah battery and fast charger, removing the typical “tool only” friction.
- Kickback brake on the angle grinder stops the wheel within roughly two seconds for added safety.
- Two-stage trigger design requires two deliberate actions to start, reducing accidental startups.
Points To Note
- Two tools in one box means you may own a die grinder you rarely reach for.
- Heavier overall kit weight compared to single-tool grinder options.
Who Will Love This
Workshop owners and pros stepping into the 20V MAX platform who want both grinding formats covered without buying separate batteries and chargers.
Reach For A Different Pick When
Anyone needing only a grinder, and nothing more, should consider the standalone DEWALT DCG412P2 kit, which keeps the focus narrow and the price lower.
The DCG412P2 has been around long enough to earn its reputation as a dependable cordless grinder. It runs an 8,000 RPM motor, ships with two batteries, and includes a quick-change wheel release that lets you swap discs without a wrench. The trigger switch includes a lock-off button, so the tool won’t fire if you bump the trigger during transport.
For homeowners and tradespeople already invested in the 20V MAX battery platform, this grinder is a familiar, predictable choice. You can hand it to a less experienced helper and trust that the lock-off and tool-free wheel changes will keep them out of trouble.

Whose Shelf It Belongs On
Pros and serious DIYers running heavy grinding applications who want the strongest braking response and the largest disc capacity DEWALT’s XR line offers.
Not Your Match When
Light-duty users should consider the DEWALT DCG412P2 kit, which ships with batteries and a charger and handles lighter home tasks comfortably.
The Bosch GWS 10.8V EC stands out in a list dominated by 18V and 20V grinders because it runs on a 10.8V platform. The smaller battery and EC (brushless) motor combine to produce a compact, lightweight grinder that fits comfortably in one hand. An innovative spindle lock makes disc changes quick, and the tool-free adjustable guard lets you reposition the safety shield without hunting for an Allen key.
This isn’t the grinder for cutting thick steel plate. It’s the one you grab for trimming tile, cleaning up small weld spots, or detail work where a full-size grinder feels clumsy. The 10.8V system is shared across many Bosch Professional tools, so if you’re already on that platform, the batteries carry over.
Advantages To Know
- Compact 10.8V form factor fits in tight spots where 18V/20V grinders feel oversized.
- Brushless EC motor keeps the tool light while still delivering useful grinding torque.
- Innovative spindle lock design simplifies disc changes.
- Tool-free guard adjustment lets you reposition the safety shield without tools.
Practical Considerations
- Lower voltage means less torque for heavy grinding, not the pick for thick stock removal.
- Battery and charger sold separately, an extra purchase if you’re new to Bosch 10.8V.
- Smaller disc size limits the types of grinding wheels you can mount.
Right Fit For
Detail-oriented users, HVAC technicians, and trim workers handling small-scale metalwork where portability outweighs raw cutting power.
Skip It When
Heavy fabrication work calls for the Makita XAG09Z or DEWALT DCG413FB, both of which deliver far greater torque and larger wheel capacity.
The XAG04Z rounds out the Makita XAG family as a brushless, trigger-switch grinder accepting 4-1/2″ and 5″ wheels. It uses the same Automatic Speed Change technology found across the line, adjusting motor output to suit the load as you cut. For existing LXT users who prefer a traditional trigger over a paddle switch, this grinder hits a familiar ergonomic note.
It predates the XAG09Z and XAG11Z, so it lacks the electric brake those newer models include. For users who don’t grind in tight, fast-paced production environments, that tradeoff is often acceptable in exchange for the lower price point of an established model.
Where It Excels
- Brushless motor and Automatic Speed Change combine for efficient cutting under varying loads.
- 4-1/2″/5″ wheel compatibility gives you flexibility across common disc formats.
- Trigger switch layout appeals to users who prefer traditional grinder controls.
- Established LXT platform compatibility keeps batteries consistent with the rest of the Makita cordless lineup.
Some Limits To Know
- No electric brake, so the wheel coasts longer after trigger release compared to newer Makita grinder models.
- Battery and charger sold separately, adding cost for users new to the LXT platform.
Who Should Grab It
Loyal Makita LXT users who prefer a traditional trigger switch and want a brushless grinder without paying for the latest brake-equipped releases.
Where Another Pick Suits Better
Users wanting the electric brake and newer safety refinements should step up to the Makita XAG11Z, which carries the same brushless motor platform with added stopping power.
