Re: What is it?
What I see is a clamp (black thumb screw on right side ) with a handle on the left that moves a cranked shaft up and down.. The cranked shaft has what looks like carbide/diamond cutter, possibly adjustable for different diameter holes. My guess is that this is used to cut round holes in tile before setting, or faucet holes in a granite counter top. I'm pretty certain that this is a carbide/diamond cutter for cutting masonry products, but just WHAT its purpose is, I am not sure.
I suffer from CDO ... Its like OCD, but in alphabetical order, LIKE IT SHOULD BE!!!
