KEO High Speed Steel Bell Center Drill 60° (Pack of 12) - Precision Hole Starter for Metal, Wood & Plastic - Perfect for Lathe, Milling & Drilling Machines

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.Center drills consist of a pilot drill and a countersink. They are used to create holes at the center of a piece of stock so it can be turned between centers on a lathe in metalworking applications. The pilot drill creates a small hole in the stock and the countersink expands the hole, leaving a small gap at the bottom of the hole that helps protect the lathe's centers from damage when the stock is turned on it.
