This is the fourth AirCat 1 HP grinder I've bought because it's so much better than other brands I've used over the years, from cheap to expensive. I'm a professional metal sculptor and I buy a grinder for every grinding job so I don't have to constantly swap out wheels, discs and burrs. These 4 grinders have taken over a lot of my other stuff - I like huskies but they have way less power - so when they die I will replace them with AirCats as I prefer them to any Jet, CH, HF, Chicago Pneumatic.
