The Brownells Aircraft Counterbore is a precision gunsmithing tool designed to cut clean, flat-bottomed counterbores in metal. The 1/4" piloted design ensures accurate alignment by using a pilot to guide the cutter, resulting in consistent, concentric cuts. Ideal for gunsmithing applications where precision counterboring is required, such as preparing screw seats or recessing fastener heads in firearm components.
