Abstract
Mass produced tools particularly useful for forming parts on screw machines and turret lathes. A plurality of identical tool blanks are stacked one upon another in a holder and are located and clamped in positions corresponding to the distance generated by their height and front relief angle thus permitting surfaces of a form to be mass produced upon the blanks while keeping the blanks interchangeable. The blanks are individually finished with required angles, radii, and side relief. These mass produced tools increase the availability and decrease the cost of form tools produced one at a time by previous methods. In addition, since they are identical, these tools are quickly changed in service without resetting or regrinding thus reducing production machine down time.
