Hyjoy Keyless Self-Tightening Chuck 0-13mm (1/2") B16 — 45# Steel for Drill Press & Electric Drills

Made from 45# steel with a refined metal texture and smooth surface, this Hyjoy keyless chuck accepts 0-13mm (1/2") drill bits and mounts to B16 spindles. Its self-tightening mechanism uses operator thrust through the handle to boost clamping force, so the jaws grip as needed during use. The keyless design allows easy hand tightening and loosening for faster, simpler chucking and unchucking. Suitable for a variety of equipment including drill presses, electric drills, lathes, boring lathes and other machines.
