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 swifels are available that will mount on your collet. Download the sizes
