Product Details
The Jacobs Ball Bearing Super Chuck is specifically engineered for heavy-duty, close-tolerance production drilling and is adaptable to a wide range of production drilling equipment, including jig borers, milling machines, lathes, and radials. It features a ball bearing construction that maximizes gripping force and drilling accuracy, while the jaws are center-ground for absolute straightness and alignment. Additionally, the jaws are specially treated to ensure extended thread life and high gripping surface hardness. The one-piece sleeve eliminates cracks between driving teeth often found in other designs, and the through-hardened sleeve teeth, along with hardened nose and keyholes, provide outstanding wear resistance. A fluted sleeve is standard, and each chuck is 100% inspected for performance and precision. The kit includes comprehensive specifications and dimensions tailored for optimum functionality and compliance with industry standards, ensuring reliability in demanding machining conditions.
