Description

Diamond Dust Holesaws are suitable for drilling ceramic, glass, marble, slate and porcelain tiles up to and including grade 5 hardness.
Designed for use with conventional power drills on a slow speed setting with no hammer action and a constant supply of water.
A real low-cost solution for drilling porcelain tiles, these must be provided with a constant supply of water to stop the tip overheating and breaking down the bond holding the diamonds onto the steel shaft.
We find a wet sponge held against the drill bit works really well.
