Value Collection CR-17 Cartridge Roll Mandrel Quick Change

Product Description

The VALUE COLLECTION CR-17 is a cartridge roll mandrel designed to hold and drive abrasive cartridge rolls in rotary tool applications. With a 3/16 inch pilot diameter and 1-1/2 inch pilot length, it accepts standard cartridge roll abrasives and delivers them to the workpiece at the correct geometry. The 1/4 inch shank diameter and 1 inch shank length fit standard die grinder chucks and compatible rotary tools. Overall length is 3-1/2 inches. The quick-change design speeds up abrasive swaps during production finishing, deburring, or surface prep work. Machinists, fabricators, and tool-and-die technicians are the primary users.

This mandrel is suited for metal finishing, deburring, and interior surface blending in manufacturing and fabrication environments. It is used wherever a die grinder or rotary tool is employed for bore work, slot finishing, or contour blending. The quick-change feature makes it practical for production settings where abrasive rolls are changed frequently. It is sold as a single unit and is compatible with 3/16 inch bore cartridge rolls of the appropriate pilot length.

Installation Notes

Installation is performed by machinists or fabricators using a standard die grinder with a 1/4 inch collet. Ensure the tool is disconnected from its power source before inserting or removing the mandrel from the chuck. Thread or seat the cartridge roll fully onto the pilot before use to prevent the abrasive from spinning free during operation. Inspect the mandrel and roll for wear or damage before each use.
