Carr Lane Manufacturing · Drill Bushings
Renewable drill bushings with chip-breaking notches on the drill-exit end. They break up chips from tough, stringy materials, reduce friction and heat buildup, and reduce damage to the workpiece.
Genuine Carr Lane parts. Equivalent ADB, Boneham and ACTEK bushings quoted on request.

Chip-breaker bushings are the choice for tough, stringy materials where long chips wrap the drill and build heat. For coolant flushing too, choose directed-coolant chip-breaker (DCCH) bushings.
The lockscrew column lists the LS size Carr Lane specifies for each OD.
On the drill-exit end of the bushing, next to the workpiece, so chips break as they leave the hole.
They are renewable bushings, so they run in a liner bushing and are held with the lockscrew or clamp listed for their OD.
