This type of tool is often used to repair parts with holes that are slightly oversize. Sometimes knurling new parts before press fitting makes assembly easier, and allows more machining tolerance. In addition, the finished assembly should be capable of transmitting more torque. A straight knurl with bevels is normally used. A carbide pin and hex wrench are included. Knurl is not included.

Setup Procedure: Mount the holder parallel to the machine spindle. Carefully guide the knurl inside the hole and just contact the work. Adjust a small amount off center, toward the work and make a test roll. If the knurl pattern is too shallow, adjust again.
