Counterbores with Interchangeable Pilots

0 products

Counterbores with interchangeable pilots feature a removable pilot, allowing for the use of various diameter pilots to accommodate different hole sizes. Commonly referred to as spotfacers, these tools create a flat-bottomed recess at the top of an existing hole, enabling bolts, nuts, or other components to sit flush or be concealed beneath the surface. The integrated pilot ensures precise centering of the counterbore within the hole for a perfectly level finish.
