Center Drills
Available801 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.
High-Speed Steel Center Drills with Plain Tip
High-speed steel center drills provide good wear resistance in a wide range of machining applications. Center drills with a plain tip are the standard choice for creating center holes in a piece of stock to prepare it for turning between centers on a lathe.

Cobalt Steel Center Drills with Plain Tip
Cobalt steel center drills are harder than high-speed steel center drills and provide good wear resistance when machining hard materials at high speeds. Center drills with a plain tip are the standard choice for creating center holes in a piece of stock to prepare it for turning between centers.
Cobalt + 60 ° Included Angle + Right Hand Cut + Double End

Center Drills with Bell Tip
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.

Hey-Type Center Drills with Bell Tip
Hey-type center drills with a bell tip have flats on their end that accept carbide inserts. They can be used on Hey machines for facing a workpiece and creating center holes on it so it can be turned between centers on a lathe. The drills have a bell tip with an additional 120° chamfer that bevels the outer edge of the hole to help protect the hole from damage during machining applications. Bell-tip center drills are commonly used in applications where parts will go through multiple machining passes and there is risk of marring the edges of the center hole. These center drills have set screw flats for locking the center drills into the tool holder.
