d. Use caution when drilling on a Porcelain sink, as it could be easily chipped. Set drill speed
to slow. Press the bit downward firmly until breaking through the slippery surface. Some
users find it easier to secure the bit by drilling through a piece of wood firmly pressed on
the surface.
e. Use coolant to disperse heat. Choose water for granite and oil for steel. Use the Water
Suction Cup to hold the coolant inside and prevent the drill bit from slipping.
f. Starting at the slowest speed, hold the drill firmly and vertically and prevent the drill bit
from slipping on the counter.
g. Once breaking through the smooth surface, swirl the drill slightly to evenly apply pressure
in a circle.
Be patient and deliberate. It can take 20 – 40 minutes to drill through 1".
