Home --> Index of metal cutting tools > HSS counterbores

A counterbore is a necessary tool to make a a cylindrical flat-bottomed hole, which enlarges another hole, or is used to create that feature. Counterbores are  made with standard dimensions for a certain size of screw and the tip of the tool is called the pilot. Smaller-diameter hole has been drilled to the standard diameter for the particular screw size, the pilot will fit the hole which  help to provide rigidity and hole center location.
