So far, I have only used it on marble tile, but it worked really great to contour the holes for a rounded square freestanding tub faucet protrusions right to the lines.
Perfect tool
Once you use a milling bit you realize how did you ever ever work without one! Get your self one of these! It will be a tool I always have in the arsenal!
These are fantastic.... When you need to notch the edge of a tile or simply enlarge a hole they are a must. I’ve been guilty of running a hole saw at an angle to try and enlarge or alter hole, no more...
Is this a dry bit only? Can it be sharpened with a dressing stone?
This bit can be used either wet or dry. This bit can be sharpened with a dressing stone, however, use caution when dressing the milling bit. This is not designed to go straight into material like a hole saw. Be sure only to dress the edge of the bit where diamond is concentrated for enlarging and shaping holes, rather than creating them.
