APPLICATIONS: 1 CH-88-16
Similar to an SF renewable bushing, but with specially designed .7188-1.0625 1-3/8 CH-88-22 LS-2
chip-breaking notches on the drill-exit end. Use to break up chips 23/32–1-1/16 1-3/8 1-3/4 CH-88-28 RC-02
from tough stringy materials, to reduce friction and heat buildup. 18.50-27.00mm 1.3750-1.374 2-1/8 CH-88-34 RK-02
Reduces bushing wear at the drill-exit end and reduces the chance 2-1/2 CH-88-40 RK-12
of tool or workpiece damage. A chip-breaker bushing should 3 CH-88-48
extend beyond its liner to allow chips to escape. Chip breakers 1-3/8 CH-112-22
are also available on other bushing types such as P, H, and DC 1-3/4 CH-112-28 LS-3
(directed coolant). .9688-1.4062 1-3/4 RC-03
