It features a 5\/16 inch pilot diameter with a 3\/4 inch pilot length that accepts standard cartridge rolls, and a 1\/4 inch shank diameter with a 1 inch shank length for secure chuck mounting. The overall assembly measures 2-3\/4 inches in length. The quick-change design reduces roll swap time on the shop floor, making it a practical choice for machinists, tool and die workers, and fabricators who cycle through rolls frequently during finishing work.\u003c\/p\u003e\n\u003cp\u003eThis mandrel is suited for use with rotary tools, die grinders, and drill presses in metalworking, fabrication, and maintenance environments. It is commonly used in applications requiring inside diameter blending, port finishing, weld cleanup, and edge deburring.
