Description
High Quality TCT Drill Bits with precision diamond-ground carbide tip for exact pilot drilling.
For drilling ceramic tiles, some porcelain tiles, mirrors and glass. Not suitable for toughened glass. The drill bit should be used at slow speed and with a coolant.
Tips:
Pour water over area to be drilled. Never allow your drill bit to overheat, take small breaks to allow it to cool by dipping it in cold water. Drilling holes without water will cause excessive heat generated during the drilling process & may cause the bit to become blunt & lead to poor drilling performance.
The operator and the hardness of the material determine overall performance.
Do not apply too much pressure as your tile/glass will break – just let the drill do the work. Use a rotary action only, not hammer action.
Wear safety glasses.
