Tightly fasten the diamond core bit in the drill's chuck. Keep the bit steady at a 45 ° angle with the starting point on the edge of the assigned area to be drilled whilst the bit is rotating. A notch will be made (this is normal). Gradually move the drill from 45° to 90° and continue drilling until finished. Allow the diamond core bit to cool down completely before proceeding to drill another hole. Water can be applied by: spraying water on the surface, using a wet sponge, attaching a water feed device.
