Rated 4 out of 5 by from Fantastic results! Depending upon which battery. I have had this grinder now since September of 2015 and use it to clean up rust on the backs of doctor backs in paper mills where there is anything from rust to grease to scale depending upon if it is either mild steel or stainless. In addition I use it to cut off bolts on the backs as well as clean up of mating surfaces, cut pipe, grind off ends of stainless doctor holders, cut plate occasionally and even granite at home . When I first used it I slapped in a SlimPack 2.0aH battery and it ate through the battery life in about 15 minutes of continuous use of rust clean up and I was sorely disappointed. However, I next used a 5.0aH FatPack and it ran for over one and half hours with minimal stops. I did notice a bit of heat after about 10 minutes of continuous use but nothing too hot to handle. In the end it is a very convenient and comfortable grinder to use.A co-worker purchased a Makita cordless version after I got this one and he is already to trying to find someone to pawn the Makita off on and purchase a Bosch cordless grinder. All in all another great Bosch product to add to my Bosch/L-Boxx family. Thanks Bosch!
