0.609" (39/64") Core Drill - HSS

Piloted Core Drills are perfect for drilling a barrel in preparation for installing a barrel liner. The removable pilot keeps the drill concentric with the original bore. This ensures a correct cut and excellent results in the finished product.

Supplied with a nominal pilot bushing. See our bushing selection HERE for additional bushing size options 

NOTE: All PTG Reamers and Cutting Tools are designed to work with petroleum-based lubricant. Water-based lubricant can give acceptable results, however the life of the tool will be reduced. For best results use petroleum-based lubricant.
