CARLAN SF-20-12-.2180 +.0001/.0004, 3/4 in, 5/16 in, 0.218 in, Slip/Fixed Renewable Bushing
SF drill bushings are replaceable bushings generally used with a liner bushing and lockscrew. Use SF bushings when you expect to replace bushings during the tooling's lifetime, or to switch bushings to perform multi-step operations with the same tooling. SF bushings combine the benefits of older S-type slip-renewable and F-type fixed renewable bushings: one side of SF drill bushings feature a lockscrew recess for fixed mounting; the other has a locking recess that allows the bushing to slip down, then rotate to lock in place. S and F types are now obsolete, and combination SF drill bushings will be supplied at no extra charge.
