Similar to an SF renewable bushing, but with passages to direct *2-1/2 DC-48-40 RK-11
coolant to the cutting area. This design is particularly good for
washing away chips, especially when ordered as the combination 1 DC-64-16 LS-2
Directed Coolant Chip Breaker (DCCH). DC bushings require special .4688-.7812 1-3/8 DC-64-22 RC-02
liners, DCL or DCHL, to direct coolant from a drilled manifold 15/32-25/32 1 1-3/4 DC-64-28 RK-02
