Meanwhile, equipped with a 20V 4.0AH large capacity rechargeable lithium-ion battery and a quick charger, it can keep the cordless angle grinder working stably for a long time

  • Worth every penny
Style: Brush
Cut like a champ. People doubted this thing till I cut solid rail in half. Made them believers.

  • The switch is not fluid but it gets the job done
Style: Brush
It’s not as powerful as a corded grinder and the on off switch is difficult to turn on but I’m pretty happy with it.

  • Pretty dam good for an off brand!
Style: Brush
I was looking for a secondary alternative battery operated tool set that didn’t have the price of Dewalt or Milwaukee. After reading reviews of these tools, I decided to give it a try. I am pretty impressed. The quality and ergonomic feel is very much equal to DeWalt or Milwaukee. This grinder comes with cut off wheels and polishing pads. A nice touch so you can start using your tool right away. It may not have the high speed RPM as Dewalt or Milwaukee but it is very close. It does everything that the light duty homeowner needs to do. You can sharpen mower blades, Cut nuts and bolts off, ect. So far the only negative I have found with this grinder is that it won’t stand up on its own if you stand it up on the battery end. I guess that’s a positive and a negative. Other than that it’s a great tool. ... show more

  • Nice Tools, Nice Price
Style: Brush
I have a complete set of these tools for what I need them for (motorcycle work). I am extremely happy with these Work Pro tools and would definitely purchase again. Though I have not used this grinder as much as the drill or the impact, I expect battery and tool life to be the same as the other tools(aka more than sufficient) for my usage. I highly recommend these tools if you are on a budget. ... show more

  • Check thread size. Too small
Style: Brush
Thread on it is too small no disc will screw in it it will need some adapter for american grinding, wire, or buffing wheels to fit. Batteries dont last long either... its alrite for home use not good for industrial or commercial use.

  • Great cordless grinder for the money
Style: Brush
Used it for the first time today. No problem cutting through 1/4” angle iron. Really like the 3 positions for the handle. I mainly bought it to grind, buff, and use with a wire wheel, but was pleasantly surprised at how well the battery did when it came to actually cutting. Once you find where it binds, it starts right back up. Stay right above where it binds, and it will cut like butter. ... show more
