B200 Round Hole Snap Ring 8mm Whip Guide Bushing by FJ Feddersen

F.J. Feddersen’s 15 mm (B200 Series) Round Hole Snap Ring Whip Guide Bushings are essential accessories for drilling straight and accurate gun barrels during manufacturing. The higher the RPM, the more the tube will whip because the tube has been crimped 110-120 degrees off-center. The result is a tube that is out of balance. FJ Feddersen’s Whip Guide Bushings help to tame the whipping by centering the drill. There is no way to stop single flute gun drills from whipping without using guide bushings such as these. FJF Feddersen makes Whip Guide Bushings in the most popular sizes for practically every application up to 65mm.
