This little gem has replaced a Dremel that I've abused for far too long. I use it for cutting, sharpening and deburring all types of materials. I have meaty paws so I can hold it like a giant pencil and do some fairly detailed work with a good carbide drill bit inserted. One speed is fine for my needs, but maybe variable speed would be nice. Actually, who cares. That thing just sucks. I find it much easier to pick up and use than an airbreaker. I have a smaller compressor, and ever since I hooked this thing up my air grinders have picked up some dust. An easy purchase and use decision.
