Centre drills are usually double sided drills with a 60' stepped point, held in a drill chuck or collet chuck in a lathe.  

The purpose of the centre drill is to create an accurate centre hole in the face of a job so as a live centre can be inserted to support the weight and load of the job, whilst turning it.
