Review on ILOVETOOL Diamond Profile Bullnose Granite Edge by Jim Reinhardt

I used it to slightly round the edge of porcelain stoneware and it worked well. I actually put it in my adjustable base drill press and adjusted the height and my press is variable speed. I've found it works best around 1100 rpm. I used it dry without water or spray. I've ridden about 28ft and the bit shows no signs of wear other than normal.
