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 hardness of the material & the operator determine the overall performance.

Do not apply too much pressure as your tile/glass will break –just let the drill do the work.

Use rotary action only but not hammer action, wear safety glasses.
