Woodworking Glossary

Countersink

A countersink is a cone-shaped recess cut at the top of a screw hole, matching the angle of a flat-head screw so the head seats flush with the surface instead of sitting proud. A dedicated countersink bit cuts the recess in one step, often combined with the pilot hole and clearance hole into a single combination bit. Counterbored holes go a step further, recessing the head below the surface entirely so it can be hidden under a wood plug.
