## Customer Reviews

### ⭐⭐⭐⭐⭐ great product
*by R***R on January 2, 2026*

great product, not to heavy and ease of use without a cord. price is good.

### ⭐⭐⭐⭐⭐ Dewalt, what else need to be said
*by D***N on January 4, 2026*

Great unit for a great price

### ⭐⭐⭐⭐⭐ Probably the best cordless grinder out there
*by C***H on January 26, 2025*

The kick back protection works amazing for when it bites and shuts the grinder off. The button lock placement isn’t the best but the lock on is nice. It’s got a lot of torque and is hard to bog down. It’s probably about the same torque as a corded one. I like the brake feature and it works well. But it does chew down the battery’s really quick, even the 5ah power stacks. I would highly recommend it to any mechanics who need a good grinder
