From Wikipedia, the free encyclopedia
Watts Brothers Tool Works
Headquarters,

Watts Brothers Tool Works is a tool manufacturer located in Wilmerding, Pennsylvania. They are known for manufacturing drill bits that can drill square holes,[1][2] including blind holes, which cannot be made with other methods such as broaching. The Harry Watts square drill bit is based on a Reuleaux triangle shape. It is used together with a guide and a particular chuck to make a square hole.[3][4] Similarly, the company also manufactures drill bits for other angular holes such as pentagons and hexagons.
