Review on DiamondSure Diamond Granite Ceramic Porcelain Cutting Tools: Premier Industrial Drill Bits by Tony Reid
Works best in twist drills
They work really well, keeping the RPMs low and the drill bit cool. I used a water spray bottle and just kept spraying while I drilled. I would recommend it to a friend.
