Spear tip drill bit 6mm for glass and tiles, 183306

Spear-point drill bit 6 mm - for glass and ceramic tile. Special type - you cannot drill glass with a standard bit.

The spear-point shape of the working end is designed for brittle materials. The bit enters the material without impact loading - it cuts rather than shatters. That's the key point: a standard carbide-tip bit under percussion will crack tile or glass.

Drill without impact, at low RPM, with water cooling. On tile - press a wet sponge against the drilling point or add a little water. Tip temperature is the main cause of tile cracking.

6 mm is the standard diameter for plugs in tiled walls. For larger holes - diamond core bits.
