I bought this at a recent auction. 1hp, has 2 diamond whhels. I pretty much only use hss lathe tools since I'm a beginner. Just getting started with mill as well. Is this only good to grind carbide tooling? Shoild i change the wheels or just hang on to it until I'm more mature as a machinist. I have an 8" baldor grinder which grinds my bits now pretty well
