You Must Apply water to the cutting edge whilst running!! This can be done using several methods, with squirty bottle and dipping bit in water as you drill, make a reservoir of water around the area to be drilled with Plumbers Putty, If the hole is to be drilled vertically i.e on a wall then you can hold a sponge around the bit soaked in water or make a bra shape cup out of plumbers putty on the wall and drill through the water etc. Removing the drill from the hole and allowing water to the bottom of the hole periodically will keep the cutting edge cool.
