BS5 HSS Centre Drill

Product Description

BS5 3/16" HSS CENTRE DRILL

Center drill bits are used to provide a starting hole for a larger-sized drill bit.
They are also used to make a conical indentation in the end of a work piece in which to mount a lathe. The centre drills are all double ended and are made up by a body and pilot at either end.

When used as a lathe centre, they provide a location for a center to locate the part about an axis.
When used as a drill centre, they ensure the drill enter's the work piece and does not wander, therefore creating an inaccurate hole.
