The Accupro CY00412000 is a new keyed drill chuck with a 1/64 to 5/32 in (0.4–4.0 mm) clamping capacity and a Jacobs Taper No. 0 (JT0) tapered mount, designed for use on drill presses, milling machines, and other machine tool spindles accepting a JT0 arbor. The chuck uses a standard keyed tightening mechanism with an included chuck key (KO-style key as specified), providing positive, repeatable clamping force for small-diameter twist drills, reamers, and similar round-shank tooling. The body is constructed of hardened steel with a black oxide finish visible in the photos, and the chuck sleeve features knurled grip rings for manual positioning before final key tightening. Marked with part number 65867772 on the body as visible in the photos, this chuck is suited for precision drilling operations in instrument making, PCB drilling, watchmaking, and other fine-tolerance applications requiring a small-capacity chuck.
