More info

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.

Disclaimer: All Chamber Reamers / Cutting tools are designed to work with petroleum based lubricant; our cutting tools are capable of being used with water based lubricant. However the life of the tool will be reduced. For best results please use petroleum based lubricant.
