Product Details
The Jacobs Ball Bearing Super Chuck is specifically engineered for heavy-duty, close-tolerance production drilling, making it adaptable to a wide range of production drilling equipment including jig borers, milling machines, lathes, and radials. It features ball bearing construction that maximizes gripping force and drilling accuracy, while the jaws are center-ground for absolute straightness and alignment. Specially treated jaws ensure extended thread life and high gripping surface hardness. The design includes a one-piece sleeve that eliminates cracks between driving teeth, which are often found in other designs. Through-hardened sleeve teeth, along with hardened nose and keyholes, provide outstanding wear resistance. The chuck includes a fluted sleeve as standard and is 100% inspected for performance and precision.
