FEATURES: These bushing assemblies are designed for use with air-feed drills, tappers, and back-spotfacers. They fit all standard drill motors, including Gardner-Denver, Keller, Aro, Buckeye, Quackenbush, Desoutter, and Ingersoll-Rand. Adaptor-tip assemblies consist of two pieces: a locking collar and a pressed-in shank. The collar screws into the air-feed drill's nosepiece, precisely aligns the shank, and locks the drill in place when rotated 30° counterclockwise after insertion in the liner. Shanks and collars can be ordered separately. STANDARD SIZES: 21000-series bushings have 3/4-16 mounting threads. This series is available in three OD sizes to fit drill diameters from .0938" to .3750":
3/8" OD (Preferred size)
7/16" OD
1/2" OD (Preferred size)
Preferred sizes can be mounted by any method, including Lock Liners, while other sizes have limited mounting options. See Dimensions page for part numbers and standard ID drill sizes. The prices shown apply to standard bushings only, with any standard USA or metric ID size within the stated range.
