7. Which cordless angle grinder should you choose?

The best cordless angle grinder for most weld cleanup and portable metal cutting is the Makita XAG04Z, with automatic speed adjustment and support for 4-1/2 in and 5 in wheels. Milwaukee adds an electronic clutch, while AOBEN is a battery kit with two batteries and a charger.

A cordless grinder makes sense when the work moves around a vehicle, railing, gate or fabrication bench without a handy outlet. If your work stays near power, compare our best corded angle grinders.

Battery choice matters too: a bare tool is often easiest if you already own its platform, while a kit can reduce the extra parts you need to buy.

For wheel choice, guards and grinder basics, start with our angle grinder guide. The picks below are ranked by how their documented features fit portable metal cutting, grinding and weld cleanup.

How we chose cordless angle grinders

The best cordless angle grinder depends on wheel fit, battery setup, control features and the work you expect to do. For a broader selection checklist, see how to choose an angle grinder.

We compared the stated specs and features, giving preference to models with relevant wheel sizes, useful safety features, and clear kit details.

Our score weighs specs, features and buyer feedback against what you're shopping for. We also considered whether a grinder has speed selection, a brake or clutch, and a handle or guard detail that helps with metal work.

Cordless angle grinder comparison

These cordless angle grinders split into bare tools and kits, so compare the battery setup along with the grinder features. Several support 4-1/2 in wheels, while some also accommodate 5 in wheels.

The best cordless angle grinders for metal cutting and weld cleanup

The right pick depends on your battery platform and whether you need a bare tool or a complete battery kit. These top-rated options cover established tool platforms, built-in protection features and adjustable speeds.

Ryobi 5133001903 R18AG-0 One+ Cordless Angle Grinder: Best for Ryobi ONE+ owners

9.7/10Our score

• 18V battery power
• 9000 rpm maximum speed
• 2.62 kg

A Ryobi ONE+ option for portable grinding and cutting tasks. The angled design and 9000 rpm maximum speed suit buyers already using the platform.

See it on Amazon

Pros

• 18V battery power
• 9000 rpm maximum speed

Cons

• Battery and charger details aren't specified here

Ryobi's R18AG-0 is a straightforward cordless choice for buyers already using the ONE+ platform. Its 18V battery power and 9000 rpm maximum speed make it a candidate for portable grinding and cut-off work where a compatible battery is already on hand.

The angled design is a practical fit for routine weld cleanup around brackets and small assemblies. At 2.62 kg, it is a heavier option than some compact cordless grinders, so consider how long you'll hold it away from your body.

This model is listed as a grinder, and the details here don't specify wheel size or a battery and charger package. Check wheel and guard compatibility for your intended accessories, and confirm whether you need to add a battery and charger.

Choose it if a Ryobi ONE+ battery is already part of your kit and you want a simple cordless grinder. If you need a bundle, compare the best cordless angle grinder with battery options.

Makita XAG04Z 18V LXT® Lithium-Ion Brushless Cordless: Best for changing grinding and cutting loads

9.6/10Our score

• Brushless motor
• Automatic speed and torque adjustment
• Fits 4-1/2 in and 5 in wheels

Automatic Speed Change technology adjusts speed and torque during operation. This tool-only grinder accepts 4-1/2 in and 5 in wheels.

See it on Amazon

Pros

• Automatic speed adjustment
• Brushless motor
• Cut-off and grinding guards included

Cons

• Battery and charger sold separately

The Makita XAG04Z is the strongest all-around fit here for buyers who move between grinding and cutting. Its Automatic Speed Change technology adjusts speed and torque during operation, while its brushless motor is designed to use battery energy efficiently.

The grinder accepts 4-1/2 in and 5 in wheels. For compatible disc picks, see our best cut-off wheels for angle grinders.

Makita includes a 5 in cut-off wheel guard, a 5 in tool-less wheel guard, a thin cut-off wheel, a grinding wheel and a lock nut wrench, which gives you a useful starting set for common work.

Makita's Active Feedback-sensing Technology turns the motor off if rotation is suddenly forced to stop. The tool is sold without a battery and charger, so it makes the most sense for buyers with an 18V LXT battery already available.

Choose this model if your work changes from cutting pipe or conduit to grinding welds and you want automatic adjustment. For more platform-specific choices, see our best Makita cordless angle grinder guide.

Milwaukee 2880-20 M18 Fuel Brushless Lithium-Ion 4-1/2: Best for kickback protection features

9.5/10Our score

• Electronic clutch for kickback protection
• Overload protection
• Anti-vibration side handle

The electronic clutch and overload protection suit metalworkers who want built-in safeguards. Its paddle switch and anti-vibration side handle support two-handed control.

See it on Amazon

Pros

• Electronic clutch
• Compatible with all M18 batteries
• 5/8 in-11 spindle

Cons

• Tool only

Milwaukee's 2880-20 suits users who want a cordless grinder with named protection features. It has an electronic clutch for kickback protection, overload protection and an anti-vibration side handle.

The tool supports 4-1/2 in and 5 in wheels, and its 5/8 in-11 spindle fits common grinding accessories. The no-lock paddle switch gives you a grip-based way to run the tool, while the side handle can help you steady it during a cut or weld cleanup.

This is a tool-only grinder, but it works with all M18 batteries. If you already have Milwaukee batteries, that shared platform can make the bare-tool setup practical.

Choose it when kickback and overload protection are high on your feature list. Compare other Milwaukee cordless angle grinders if you want to see more M18 options.

4

DEWALT 20V MAX* Angle Grinder Tool Cordless: Best for a fast stopping wheel

9.3/10Our score

• Brushless motor
• Brake stops wheel in 2 seconds or less on average
• Kickback Brake

The DCG413B combines a brushless motor with a brake that stops the wheel in 2 seconds or less on average. Its Kickback Brake responds to a pinch, stall or bind-up.

See it on Amazon

Pros

• Wheel brake
• Kickback Brake
• Two-stage trigger

Cons

• Battery and charger sold separately

The DEWALT DCG413B centers on stopping and restart control. Its brake stops the wheel in 2 seconds or less on average, and the Kickback Brake engages when the tool senses a pinch, stall or bind-up.

The brushless motor requires no brush changes. A two-stage trigger takes two actions to activate the grinder, and E-Switch Protection requires the trigger to be cycled after a power outage or unexpected shutdown.

This 20V tool-only model includes one angle grinder, with battery and charger sold separately. Choose it if you have a DEWALT battery platform and want a brake-focused tool for cut-off and grinding work.

5

AOBEN Cordless Angle Grinder 4-1/2 inch: Best for a ready-to-use battery kit

9.2/10Our score

• Two 21V 4.0Ah batteries
• Three speed settings
• Two wheel guards

AOBEN includes two batteries, a charger, guards, and cutting, grinding and sanding wheels. Its three speed settings suit buyers who want a kit rather than a bare tool.

See it on Amazon

Pros

• Two batteries and charger included
• Three speed settings
• Two wheel guards

Cons

• Battery packs from other brands aren't compatible

AOBEN is the most complete kit in this group for buyers starting without batteries. It includes two 21V 4.0Ah batteries, a charger, two wheel guards, and cutting, grinding and sanding wheels.

Its brushless motor has three speed settings, with a maximum stated speed of 9500 rpm. AOBEN also provides regular and half-covered guards, which gives you guard options for different cutting tasks.

The kit uses its own battery packs, which aren't compatible with other brands. AOBEN notes that overload or overheating protection can pause work, so release the switch and let the tool recover if protection activates.

Choose AOBEN when an all-in-one bundle and adjustable speeds matter more than sharing batteries with an established platform. If variable speed control is your main concern, compare the best variable speed cordless angle grinder picks.

6

DEWALT 20V MAX* XR Brushless Cordless 4-1/2-5: Best for higher stated no-load speed

8.8/10Our score

• Brushless motor
• Up to 9000 rpm no-load speed
• Anti-rotation system

This tool-only DEWALT XR grinder is rated for 4-1/2 in and 5 in wheels. Its anti-rotation system senses tool motion and shuts it down if motion is excessive.

See it on Amazon

Pros

• Up to 9000 rpm no-load speed
• Anti-rotation system
• 5 in guard included

Cons

• Battery and charger sold separately

The DEWALT DCG410B is designed for 4-1/2 in and 5 in wheels and has a brushless motor rated up to 9000 rpm with no load. Its anti-rotation system senses the tool's rotational motion and shuts it down if that motion is excessive.

DEWALT states that the motor delivers up to 1,590 MWO. The tool includes a 5 in Type 27 guard, side handle, wrench and inner and outer flange, but the battery and charger are sold separately.

The tool-connect chip-ready feature supports asset tracking when paired with the chip and Site Manager app. Its wireless control system can also work with a compatible DEWALT dust extractor.

Choose this model if you need a 5 in wheel option and want the anti-rotation system. See our best DeWalt XR angle grinder guide for more from the XR line.

7

SEESII Cordless Angle Grinder 4-1/2 Inch: Best for three selectable speeds

8.7/10Our score

• Three speed settings
• Two 4000mAh batteries
• Side handle mounts in two positions

Three speed settings give this kit options for cutting, grinding and polishing. Two batteries and a charger come with the tool.

See it on Amazon

Pros

• Three speed settings
• Two batteries and charger
• Two-position side handle

Cons

• Brand battery compatibility is limited

SEESII gives you three selectable speeds: 5000, 7500 and 10000 rpm. That range makes the grinder a fit for buyers who want to adjust speed across cutting, grinding and polishing tasks.

The kit includes two 4000mAh batteries, a charger, a side handle, cutting wheels, flap wheels and a carrying bag. The auxiliary handle can mount in either of two positions, which helps adapt the grip to the angle of the work.

SEESII lists this as an 18V battery-powered grinder, and the included batteries are part of its own kit. Check wheel compatibility and the included guard arrangement against your planned metal-cutting work before use.

Choose it for adjustable speed and a battery bundle in one purchase. If you want a smaller tool body for detail work, browse our best mini cordless angle grinder picks.

CRAFTSMAN V20* Angle Grinder: Best for a three-position handle

8.6/10Our score

• 8500 rpm
• Three-position handle
• Tool-free guard adjustment

The CMCG400B has a three-position handle and tool-free guard adjustment. It includes a grinding guard, grinding wheel and spanner wrench.

See it on Amazon

Pros

• Three-position handle
• Cast metal gear housing
• Grinding wheel included

Cons

• Battery and charger sold separately

The CRAFTSMAN CMCG400B offers a three-position handle and a tool-free guard position. Its cast metal gear housing dissipates heat during extended use, while the over-molded handle is shaped for grip comfort.

The package includes a grinding guard, grinding wheel and spanner wrench. It is a tool-only model, so you'll need a compatible V20 battery and charger if you don't already own them.

Its stated maximum speed is 9000 rpm. Consider the three handle positions if you regularly change the angle of approach around welds or need to work across different surfaces.

Choose CRAFTSMAN when you want the basic grinder accessories in the box and already own a V20 battery. For another brand comparison, see our best Bosch cordless angle grinder page.

RYOBI PCL445B 18V Cordless 4-1/2 in. Angle: Best for a simple Ryobi bare tool

8.1/10Our score

• 9000 rpm motor
• Three-position side handle
• Spindle lock

This Ryobi bare tool has a 9000 rpm motor, spindle lock and three-position handle. It suits buyers who already have a compatible battery and charger.

See it on Amazon

Pros

• 9000 rpm motor
• Three-position handle
• Die cast metal gear case

Cons

• Battery and charger sold separately

The RYOBI PCL445B is a bare tool for buyers with an 18V Ryobi battery and charger. Its motor reaches 9000 rpm, and a three-position side handle supports grip changes as you move around the work.

A spindle lock helps with accessory changes, and the die cast metal gear case is built into the tool. Ryobi also describes a tool-free adjustable guard and onboard wrench storage for this model.

The package is listed as a bare tool, so plan on using a compatible battery and charger you already have or sourcing them separately. At 5.6 lb, it is the heaviest option in this roundup by the stated weight figures.

Choose it if you want a simple Ryobi 18V grinder with a familiar platform. For battery options, our best angle grinder battery guide explains what to check before buying.

How should you choose a cordless angle grinder?

Choose a cordless angle grinder by matching the battery platform, wheel size and job type before comparing extra features. Metal cutting and weld cleanup put different demands on the same tool, so plan the wheels and guards as carefully as the grinder.

Which battery setup fits your work?

A tool-only grinder costs you less setup time if you already own batteries for that brand. If you're starting fresh, compare a complete cordless angle grinder with battery kit against the cost and convenience of joining a brand's battery platform.

Check voltage and compatibility by model. AOBEN says its batteries are not compatible with other brands, while Milwaukee says the 2880-20 works with all M18 batteries.

What wheel size do you need for cutting and cleanup?

Use the wheel size approved for the grinder, guard and task. Several picks support 4-1/2 in wheels, and the Makita, Milwaukee and DEWALT XR models also list 5 in compatibility.

A 4-1/2 in grinder is a common size for general fabrication tasks. If you want more flexibility, check whether the tool includes the guard for each wheel size you plan to use.

When is variable speed useful?

Variable speed is useful when you want to adjust the wheel speed for different tasks. AOBEN offers three speeds up to 9500 rpm, and SEESII has three set choices from 5000 to 10000 rpm.

Some grinders automatically change speed and torque to match load. The Makita XAG04Z does this with Automatic Speed Change technology, which differs from selecting a speed yourself.

Which safety features should you compare?

Look for features that match the way you work and remember that they do not replace safe setup. The DEWALT DCG413B has a brake and Kickback Brake, while Milwaukee specifies an electronic clutch and overload protection.

Use the correct wheel, guard and side handle for each job. Keep your grip stable, let the tool reach speed before contacting the work, and remove the battery before changing a wheel.

How do cordless grinders compare with corded models?

Cordless grinders are easier to move between work areas and don't need an outlet beside the job. Corded models avoid battery runtime limits, which can matter when you grind for long periods or don't have spare packs.

For mobile repair and cleanup, cordless can save time moving equipment and extension cords. If you need repeated heavy cuts, keep a charged spare battery available or consider whether a corded grinder is a better fit.

Frequently asked questions

What should I look for in a cordless angle grinder?

Match the grinder to your wheel size, battery platform and work. For metal cutting and weld cleanup, check guard compatibility, handle positions, speed, and whether the tool includes a battery and charger.

Safety features such as a brake or electronic clutch can also guide your choice.

Are cordless angle grinders powerful enough for metal cutting?

Yes, cordless grinders can cut metal when paired with a suitable cut-off wheel and guard. The Makita, Milwaukee, and DEWALT options here support 4-1/2 in wheels, and some also fit 5 in wheels.

Use the wheel type and size specified for your tool.

Should I buy a bare tool or a cordless angle grinder kit?

Choose a bare tool if you already own a compatible battery and charger. A kit such as the AOBEN or SEESII includes batteries and a charger, which can be simpler when you are starting a battery platform.

Check battery compatibility before ordering.

Can one cordless grinder handle cutting and weld cleanup?

A grinder can handle both jobs with the right accessory: use a cut-off wheel for cutting and a grinding or flap wheel for cleanup. Change the wheel only with the tool powered off and the battery removed.

Use the correct guard for the wheel and task.
