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).
ONE-PIECE CONSTRUCTION: One-piece Gun-Drill Bushings offer maximum accuracy and faster installation. One Gun-Drill Bushing is required for each gun-drill size. The Eldorado deep type shown here has an extra-long extension beyond the head (choice of 1/2", 1", 1-1/2", or 2" extension).
