Description
- Manufactured from high speed steel for increased tool durability.
- Manufactured as per BS328 Standards. 60° inclusive angle
- Center drills have a conical shape with a pilot tip that creates a small, precise indentation in the workpiece.
- The primary purpose of center drills is to create a starting point for the subsequent drilling operation. They help prevent the twist drill from wandering and ensure that the hole is accurately centered.
- Many center drills are double-ended, providing two cutting tips. This feature extends the tool’s life and provides flexibility in case one end becomes dull.
