Sets of Counterbores with Built-In Pilots

Integrated pilot counterbores, also known as solid pilot counterbores, are crafted from a single piece of metal, ensuring the pilot remains fixed. Ideal for creating precise flat-bottomed cavities atop holes, they allow bolts, nuts, or similar components to sit flush or be concealed. The integral pilot guarantees perfect centering for a level finish. Each set includes a variety of sizes to accommodate different hole dimensions.
