The best cordless angle grinders

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

DEWALT DCG418b angle grinder

DEWALT 60V MAX – Flexvolt angle grinder (DCG418b)

our score: 9.6
  • Latest DEWALT angle grinder
  • Powerful with high RPM
  • Efficient battery usage
  • Maximum safety features

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.

Safety features

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.

Another great safety feature is the E-switch protection. This will prevent the grinder from suddenly starting after a power outage or unexpected shutdown.

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.

DeWALT DCG418B Pricing

The price of this grinder is also something we really like! It’s one of the cheapest, quality grinders on the market today offering the best value for money. You can either buy this grinder as a standalone tool or you can buy it in a kit. You can find the best price for the DEWALT 20v Max XR on Amazon.

Makita XAG04Z 18V LXT

makita angle grinder

Makita 18V LXT angle grinder (XAG04Z)

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

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.

Makita XAG04Z Pricing

The quality you get for the price is outstanding. This product could last you a lifetime if you treat it with care. We found the best place to buy it is on Amazon. They ofter have good deals on the standalone tool. We also love the Makita kit they sell since all these tools work on the same battery system.
