Vevor 8-Inch 3-Jaw Lathe Chuck

The VEVOR 8-inch three-jaw chuck is a precise self-centering clamping device designed for metalworking applications. With a clamping range of 4-200 mm internally and 70-200 mm externally, this chuck accommodates various workpiece sizes across multiple machining platforms, including lathes, milling machines, and machining centers. Made from high-quality materials such as an HT300 cast iron body and hardened 20Cr steel jaws with a hardness of 53 HRC, the chuck offers exceptional durability and long-term reliability in demanding workshop environments. The precision-ground worm gear mechanism made of 40Cr steel with a hardness of 45 HRC ensures consistent centering precision and smooth operation throughout the chuck's lifespan. With an outer diameter of 200 mm and a through hole of 65 mm, this USA-made chuck features a surface quality better than Ra0.8 to achieve minimal runout deviation and superior workpiece concentricity. The included T-key fastening screws and hex key facilitate straightforward installation and secure mounting on machine spindles. The oil-coated surface provides corrosion resistance and maintains dimensional accuracy under varying workshop conditions. Weighing 12.3 kg, this high-performance chuck ensures stability during high-speed operations, while the three-jaw self-centering design allows for quick workpiece setup and even clamping force distribution. Suitable for professional machining applications requiring precise clamping solutions, this lathe chuck combines robust construction with operational efficiency for enhanced machining accuracy and productivity.
