Carr Lane Manufacturing · Drill Bushings
Gun-drill bushings guide long, thin gun drills on Eldorado, Drillmation, DeHoff and Lahr machines. Like SF renewable bushings but reversed, with the drill bearing at the head end that contacts the workpiece.
Genuine Carr Lane parts. Equivalent ADB, Boneham and ACTEK bushings quoted on request.
Two-piece system: a GDL liner holds replaceable GDI inserts. A 1-3/4" OD liner fits all 5/16" OD inserts.

The two-piece liner and insert system gives maximum economy and flexibility: replace only the worn insert. One-piece bushings are available for Eldorado and DeHoff machines.
GDL part numbers follow GDL-[OD in 64ths]-[length in 16ths]-[ID in 64ths], e.g. GDL-88-22-16 = 1-3/8" OD, 1-3/8" long, 1/4" ID.
Two-piece (liner + insert) is more economical when inserts wear often, because only the insert is replaced. One-piece bushings suit Eldorado and DeHoff machines when you want a single part.
