33UM78 Center Drills

Bulk orders will be discounted, please contact us.

Bell-tip center drills create a hole at the center of a piece of stock so it can be turned between centers on a lathe. They have an additional 120° chamfer on their tip that bevels the outer edge of the center hole to strengthen it and help protect the hole from damage in applications where the piece of stock will go through multiple machining passes and there is risk of marring the edges of the center hole.
