Counterbores & Pilots

Select from single-point tools, such as turning and boring tools, or multi-point tools, like end mills and drill bits.
Counterbores are used to enlarge an existing hole or to create a seat for a fastener so that it lies flush with the workpiece. Pilots guide the counterbore as it cuts to ensure the recessed hole is level. Pilots can be permanently attached or they can be removed, allowing for varying pilot diameters to be used.
