Counterbore And Countersink Pilot

Counterbore and countersink pilots are machine tool accessories used in metalworking machinery.

A counterbore pilot is a cylindrical tool that is used to guide a counterbore drill bit. A counterbore is a type of hole that is wider at the top and narrower at the bottom. It is used to create a recessed area for a fastener, such as a screw or bolt, to sit flush with the surface of the material. The counterbore pilot ensures that the counterbore hole is drilled accurately and to the correct depth.

A countersink pilot, on the other hand, is used to guide a countersink drill bit. A countersink is a conical hole that is drilled into a material to allow the head of a screw or bolt to sit flush with the surface. The countersink pilot ensures that the countersink hole is drilled accurately and at the correct angle.

Both counterbore and countersink pilots are essential accessories in metalworking machinery as they help to create precise and professional-looking recessed areas for fasteners.
