3 products
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.

Center Drills with Radius Tip
Radius-tip center drills have a tapered flute that allows them to create more accurate holes than other styles of center drills. They are commonly used in high-precision applications to create holes at the center of a piece of stock so it can be turned between centers on a lathe.
