The best cordless angle grinders

Here is a list of what we believe are the best cordless angle grinders:

Hphtools’ Choice

DEWALT DCG413b angle grinder


our score: 9.8
  • 4-1/2″ inch angle grinder
  • 6500 RPM
  • XR Battery
  • Good safety features

Pros and cons

According to our experts
  • Plus icon indicating a pro

    This is a great angle grinder if you are looking for a good tool on a budget

  • Plus icon indicating a pro

    The DEWALT DCG413b is not the latest angle grinder. However, it offers the beste value for money

  • Minus icon indicating a con

    Flexvolt batteries can not be used with the DCG413b

Our favorite cordless angle grinder is the DEWALT 20V MAX! This grinder has a voltage of 20 volts and a high-efficiency brushless motor. This angle grinder also has a break stop system of 2 seconds making it extra safe to use.


Could this be the safest angle grinder to use? We believe so… One of its great features is a kickback brake that is engaged when a pinch, stall, or bind-up event is sensed. It will break and shut off the angle grinder completely.

Grip and accuracy

Basically, all products of DEWALT are well thought out and optimized for control. The DEWALT 20V MAX is no exception to this. Also, the 2 stage trigger on the drill is easy to control and the grinder feels very natural to use.

Budget grinder

Makita 18V LXT angle grinder (XAG04Z)

our score: 9.2
  • Budget angle grinder
  • Good price/quality
  • Long battery life
  • Decent RPM

Pros and cons

According to our experts
  • Plus icon indicating a pro

    Makita is known for making high quality tools and this angle grinder is no exception.

  • Plus icon indicating a pro

    The Makita XAG04Z is a perfect example of a budget angle grinder that can be used for beginners as well as experts.

  • Minus icon indicating a con

    This Angle grinder has slightly slower RPM. This is not really a problem but can cause some trouble when cutting heavy steel for example.

In second place we have the Makita XAG04Z 18V LXT. Another great cordless grinder for all your grinding jobs. This angle grinder is a bit cheaper than the 1st place on this list, which makes it a great budget choice.

Just like all the other products in this Makita line, this grinder has an 18-volt Lithium-ion battery. This makes it especially interesting if you already have some other products in the Makita X line.

Safety features

This angle grinder also has a great safety feature that we absolutely love. Active feedback makes sure that the angle grinder stops and turns off once the motor is forced to stop.

Grip and accuracy

This angle grinder has a more minimal design which we can really appreciate. The grip is traditional and decent for an angle grinder. However, we found is not the most sturdy grinder on this list to hold.

Frequently asked questions

We recommend the DEWALT 20V Max angle grinder for removing paint and rust. This angle grinder has great precision and a controllable speed.

Polishing granite edges is a very delicate job and therefore we recommend you use the Makita XAG04Z 18V LXT. This is an 18v angle grinder that is perfect for fine jobs like this.

Heavy, dense materials like concrete require a powerful angle grinder. Therefore, the strong Milwaukee cordless angle grinder is a great option for this kind of job.

Milwaukee and DEWALT both manufacture high-quality angle grinders. Milwaukee is the biggest supplier of power tools in North America whereas DEWALT has the better warranty program. There is not really a winner between these two, their angle grinders are equally as good.
