Center drill bits are used to provide a starting hole for a larger-sized drill bit or to make a conical indentation in the end of a work piece in which to mount a lathe centre. They are available in metric sizes or BS (British Standard) sizes. 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 (live, dead, or driven) center to locate the part about an axis. When used as a drill centre, they ensure the drill enters the work piece and does not wander, therefor creating an inaccurate hole.
