These aluminum lathe faceplates are CNC machined for minimal runout and feature large screw holes for more workholding power. They are available in 2'' diameter (48582) and 3'' diameter (44919) sizes. The 3'' diameter faceplate includes a set screw for use on reversible lathes, but the 2'' does not have a set screw. The hubs on both are as short as possible to minimize vibration, and the thread sizes are clearly laser cut into the hubs for easy identification. 1''-8 TPI thread.
