"Micro" Core Drills These core
drills are particularly suited for drilling glass, silicon
and ceramic materials. It is strongly recommended that
coolant be used through the center of the drill. It is
sometimes possible to flood cool, but this does not
effectively remove swarf and does not cool as well so
it hastens tool wear.
Water swivels are available that will mount on your
collet (See below)
