Center Drills

 

Center Drills (General Purpose):

Center drills are primarily used to create a tapered feature in the end of a part or stock to provide a secure contact point for a live or dead center. The straight pilot drill section starts the hole, and provides clearance for the point of the center, so it does not contact the bottom of the hole. The larger countersink section creates a taper in the stock that matches the angle of the center. These center drills feature a 60° countersink angle that matches the taper of our high-precision live centers.

 

Center Drill Sizes:

Center drills come in a range of sizes. The size of the center drill needed is determined by the size of the part being supported, along with the size of center needed.

CAUTION: Center drills are not recommended for use as spotting tools for carbide twist drills. Using a spotting tool with a point angle sharper than the point angle of the drill can damage the carbide drill.
