🔧 What is a Centre Drill?

A centre drill is a short, rigid tool used to create a conical hole at the end of a workpiece. This hole serves as a guide for tailstock centers or larger drill bits in turning and milling operations. The Totem BS4 centre drill is known for its precision tip, robust construction, and excellent chip control, making it a staple in any metalworking setup.
