Gibraltar K12-250 10 in 4-Jaw Self-Centering Lathe Chuck

The Gibraltar K12-250 is a new 10-inch (250 mm) 4-jaw self-centering scroll chuck manufactured to the K12 DIN 6350 standard, featuring a forged steel body with a through-bore center hole and a single-piece scroll plate that moves all four jaws simultaneously for rapid, repeatable centering of round and square stock. The chuck ships complete with two sets of reversible jaws (stamped 1L–4L, part series 2795 as visible on the jaw faces), a T-handle chuck key, and mounting hardware, giving the user both inside and outside gripping capability without jaw swaps. The K12 designation corresponds to a short-taper (camlock or threaded-backplate) mounting system with 250 mm body diameter, making this chuck compatible with most manual engine lathes and rotary tables that accept a D1-6 or threaded L0/L1 spindle nose adapter; a backplate adapter (sold separately) is required to match the specific lathe spindle. Typical applications include manual engine lathes in toolrooms and job shops where fast, self-centering workholding is needed for cylindrical parts up to the chuck's capacity.
