Piloted Core Drills

Piloted valve guide core drills are manufactured from High Speed Steel and intended to be used in a Valve Guide and Seat Machine, Bridgeport style machine, or bed mill.

Valve guide core drills are designed to be used with valve guide core reamers to achieve a final finished size for press fit guide installation.

Our piloted core drills are available in several different shank sizes and styles to fit most common Valve Guide & Seat machines or vertical mills.
