Chuck keyless type 13mm X1/2-20UNF

Professional-grade 13mm keyless metal chuck engineered for high-performance drilling on construction sites and in intensive workshop environments. Built with an all-metal body for superior heat and wear resistance, eliminating the limitations of plastic-sleeved alternatives. The keyless mechanism enables rapid bit changes without a chuck key, boosting productivity on the job. Many models feature self-tightening design—clamping force increases naturally as torque is applied, securing bits firmly and minimizing slippage even through tough materials. Standard 1/2" x 20UNF threaded mount fits a vast range of corded and cordless drills from leading manufacturers. This industry-standard fitment reduces run-out and vibration, delivering improved accuracy and cleaner holes. Accepts bit shanks from 1.5mm to 13mm, handling everything from precision bits to heavy-duty masonry and metal-drilling tools. Textured metal sleeve provides ergonomic grip for maximum hand-tightening torque and consistent clamping performance. Ideal for drilling wood, steel, plastics, masonry, and bricks across construction, industrial, and DIY applications.
