Clean, precise tenon joints start with the right tool. This four-piece square tenon drill set is designed for woodworking where sharp, clean results matter – from furniture joints to cabinet making – all without rough edges that delay finishing.

Each drill is made of carbon steel with CNC-milled cutting edges and produces smooth, precise square tenon holes in the four most common tenon hole sizes. The chip removal design keeps cutting resistance low, so each pass through the wood is faster and more controllable. A drill adapter holder is required for use and is sold separately.
