Bison 01328 Hard Top Jaws 3-Jaw Set Lathe Chuck Hard Top Jaws

This is a new set of three (3) Bison hard top jaws, part numbers 01328-1, 01328-2, and 01328-3, designed as replacement or spare hard jaw sets for compatible Bison 3-jaw scroll lathe chucks. The jaws are manufactured from hardened steel and feature a distinctive two-piece design with a hard serrated top jaw mated to a master jaw base body, with the characteristic stepped staircase profile visible in the photos and a threaded hex-socket bolt hole for secure jaw attachment. The serrated gripping face on each top jaw uses a standard 60° tooth pitch serration pattern common to Bison interchangeable top jaw systems, allowing secure workpiece clamping on a lathe chuck. The three jaws are individually numbered (1, 2, 3) for proper indexing and balanced assembly in the chuck body. These are sold as a complete matched set of 3 jaws and are intended for external (OD) gripping applications; buyers should verify chuck size compatibility with their specific Bison chuck model before ordering.
