Details: 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.
