Well I'm new to this grinder but I've been using the tool long enough to know what works and what doesn't. play, let's see how it works) now I'm making some cabinets. I run a compressor in my garage (it's a big master) and this thing just won't stop. It took me a while to get comfortable, but now I've made it. I like it. I can see where people need extra mills now (the ones with dots) but this is great! Easy to set up, easy to clean, this girl is happy
