Tips:

Always use water for lubrication, otherwise the diamond core bit will burn out.

Can be used with a standard electric drill.

Start your hole diagonally. Make a circular track, then keep the drill straight. Reduced drilling speeds, reduced drilling pressure, and increased utilization. Water lubrication significantly extends drill bit life.
