Countersinks & Counterbores

Select from single-point tools, such as turning and boring tools, or multi-point tools, like end mills and drill bits.

Why Motion for Countersinks & Counterbores?

Countersink and counterbore tools create holes for fasteners to sit flush with or below the surface of a workpiece. Countersinks make cone-shaped holes that accommodate the head of a screw or rivet. They’re also used for chamfering and deburring. Counterbores increase the diameter at the mouth of a pre-drilled hole, creating a seat for a fastener.
