Thread Adaptor 1" x 8tpi Male to 1 1/4" x 8tpi Female

These thread adaptors are precision CNC machined from tool steel to an accuracy of +/-0.01mm to ensure concentricity. They allow for the interchange of threaded woodturning accessories such as chucks, faceplates, woodscrew chucks to suit varying lathe spindle threads. The face of the boss is precision machined to ensure that the face of the mating accessories sits true, resulting in perfectly balanced turning and super-fine finishing. This adaptor has a 1" x 8tpi male thread with a 1 1/4" x 8tpi female thread. ©
