Product Details
The Jacobs plain bearing chuck is the world's most widely used chuck for medium or heavy-duty portable, bench, or floor mounted power tools. This industrial quality chuck features fully hardened and ground working components, providing exceptionally high accuracy, gripping power, and durability. It is available in heavy and medium duty models compatible with threaded or taper mounting, with jaws that are center-ground for absolute straightness and alignment, and specially treated to 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, and through-hardened sleeve teeth, along with hardened nose and keyholes, ensuring outstanding wear resistance. Each chuck is 100% inspected for performance and precision.
