Alfa Tools ¼-Inch x 1½-Inch Cartridge Roll Mandrel

The Alfa Tools AM75167 is a precision mandrel designed to hold cartridge rolls for deburring, polishing, finishing, and light abrasive work. It features a ¼-inch pilot diameter and 1½-inch pilot length, paired with a ¼-inch shank diameter and 1¼-inch shank length, yielding an overall length of 3½ inches. This configuration gives excellent reach into deeper internal geometries while maintaining concentric stability and rigidity. The mandrel is ideal for use in tool rooms, machine shops, and fabrication environments where consistent, controlled finishing inside holes, bores, and slots is required.
