Centre Drills (3 Products)
Centre drills are short, rigid cutting tools originally designed to create countersunk locator holes for tailstock centres when turning stock between centres on a lathe. Machinists and toolmakers rely on these specialized bits to establish an accurate starting point on rotating workpieces without wandering off-centre. Their specific point geometry matches standard lathe centre angles for secure mounting.

Selecting the Right Centre Drill
Choosing the correct centre drill requires matching the pilot diameter and body size to the scale of your lathe work and stock dimensions. You must also select between Type A standard profiles and Type R radius forms depending on the stress distribution and relief requirements of your turned components. High-speed steel construction ensures adequate rigidity and wear resistance under rotation.
