Hyjoy 5/8-Inch Keyless Drill Chuck with JT33-MT2 & JT33-MT1 Taper Arbors (inner thread 3/8"X16TPI and 1/4"x20TPI) for Drill Press

This Hyjoy keyless drill chuck accepts drill bits, pen mandrel shafts and workpieces up to 5/8 inch in diameter. It includes one JT33-MT2 taper arbor with inner thread 3/8"X16TPI and one JT33-MT1 taper arbor with 1/4"x20TPI, allowing secure attachment when fitted into a lathe headstock and used together with a draw kit to prevent loosening. The keyless design makes bit changes quick and tool-free, ideal for drills, drill presses, lathes and other machines. Three hardened jaws provide reliable clamping force, and the chuck has undergone quenching hardening for improved wear resistance.
