Bump type knurl holders are best suited to shorter work or longer work if knurling can be done close to the chuck or tail stock. If a long, raised diamond pattern is required, a two die holder, using one right hand and one left hand knurl is recommended (pages 4-6). Carbide pin and hex wrench are included. Knurl is not included. Setup Procedure: Mount the holder perpendicular to the spindle, in the turret or cross-slide. Move the holder toward the spindle until the knurl just contacts the work. Adjust a small amount deeper and make a test roll. If the knurl pattern is too shallow adjust it again.
