Keyless Design No keys or tools required to tighten or loosen the chuck. Apply hand pressure to tighten or loosen for a quicker, easier chucking and unchucking experience. SelfTightening Features a thrust bearing that increases clamping force as needed, securing the drill bit more effectively. The selftightening mechanism supports higher output torque and provides enhanced stability during drilling operations. Wide Compatibility Suitable for use with drill machines, milling machines, lathes, boring lathes, and electric hand tools. Its versatility makes it a practical addition for both professionals and DIY enthusiasts. Construction Constructed from durable materials and built to last. Designed to withstand frequent use and deliver reliable performance across various applications. Use scenarios Metal fabrication: pair with a drill press or milling setup to quickly change bits and maintain a strong grip during torque drilling. DIY projects: easily switch between bits for wood, plastic, or light metal tasks, reducing downtime and improving workflow. Workshop setup: use in a mixedtool environment (drill, lathe, boring lathe) to enhance efficiency when changing between operations and maintaining stable bit engagement.
