Centre drills are double ended drills with a 60 deg stepped point, held in a drill chuck or collet chuck in a lathe or drill press they create a accurate pilot for a drill bit. Also an accurate centre hole in the face of a job for a live centre to be inserted to support the end of the job, whilst turning it.
Longer jobs generally require a live centre from the tailstock of the lathe to support the job, which prevents chatter and run out.
