Standard Taper Male Extensions.
3.000" TPF WITH 1.00" DIAMETER AT LARGE END OF TAPER.
SHORT MALE EXTENSIONS provide increased utility because grinding wheels already mounted do not need to be dismounted. This feature is especially useful when grinding with diamond wheels. Units come complete with floating nut spacer 00662 (FN-1) and 1/2-13 wheel end-nut. A 1-1/8” wrench flat on the body makes installation and removal easy. The hex spindle nut must be selected separately to suit your machine.*
