The Bosch GWS12V-30 12V Max 3 In. Angle Grinder is ideal for the pro who needs a compact powerhouse to get to those quick, difficult cuts in tight spaces other tools can't. With its brushless motor design and optimized gear structure, this efficient grinder produces 19,500 no-load rpm at only 1.5 Lbs. (tool only, not including battery). The grinder was engineered to fit the palm of a user’s hand, for outstanding ergonomics and control. This versatile tool is powerful enough to cut threaded rod, strut, conduit, tile and more. It features an innovative gear-mount design for fast wheel change; just pull the locking clip and unscrew the spindle screw. The grinder has restart protection to help prevent accidental start-up and overload protection to reduce the risk of the motor overloading or overheating. It also features fast braking time, stopping the wheel after the grinder is turned off.

Awesome little tool!

Would Recommend

I use this thing at work all the time to cut bolts and stainless sheeting. I have even cut thicker mild steel with it. It's done things that I thought it would not do time and time again. It's so small and feels so good in the hand it's really a pleasure to use.

Compact go-to tool for me for cutting and grinding

Would Recommend

I've used this for 6 months now. It has become a go-to tool for me for cutting and grinding. It's very compact so I reach places that my corded grinder cannot. I've upgraded to the large battery pack for more power and longer run time. I'd buy again.

Powerful and gets the job done

Would Recommend

[This review was collected as part of a promotion.] This has really come in handy for me and my crew. There's no task that it couldn't handle. Don't let it's simple look fool you, it has the power you'd want in an angle grinder and then some.
