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: 22000-series bushings have 1"-14 mounting threads. This series is available in four OD sizes to fit drill diameters from .1875" to .4688":| | 7/16" OD | | | 1/2" OD | | | 9/16" OD | | | 5/8" OD (Preferred size) |
Preferred sizes can be mounted by any method, including Lock Liners, while other sizes have limited mounting options.
