FEATURES: Gun-Drill Bushings are used on gun-drilling machines, such as Eldorado, Drillmation, DeHoff, and Lahr. These bushings are similar to SF renewable bushings, except reversed, with the drill bearing at the bushing's head end, which contacts the workpiece. Gun-Drill Bushings are available in a choice of one-piece construction or two-piece construction (a liner and an insert).
TWO-PIECE CONSTRUCTION: The Gun-Drill Liner Bushings shown here are used together with Gun-Drill Inserts. This two-piece system offers maximum economy and flexibility. Only a few liner sizes are required to hold a wide range of replaceable inserts to fit specific gun-drill sizes.
STANDARD SIZES: Available in 1", 1-3/8", and 1-3/4" OD sizes. See Dimensions page for part nummbers. The prices shown apply to standard bushings only, as listed in the table.| | GDL-112-28-20 | | 1-3/4" OD liner bushing to
