Awesome tool, wish I would of bought it sooner
Customer review from milwaukeetool.com logo
I'm a lube tech and light repair mechanic for a large concrete company in the midwest US, I have to change out cutting edges on loader buckets occasionally, before I bought this grinder I would have to use an air grinder that ran off the service truck to clean the dirt from around the mounting bolts and the air grinder would bog down all the time and it was just a hassle, with the new milwaukee grinder I dont have that problem, I've put my full body weight on it and it just keeps going, awesome tool
