Value Collection CR-7 Cartridge Roll Mandrel Quick Change

Product Description

The VALUE COLLECTION CR-7 is a cartridge roll mandrel designed to hold abrasive cartridge rolls for use in die grinders and other rotary tools. The mandrel features a 0.125-inch pilot diameter and 0.5-inch pilot length, paired with a 0.25-inch shank diameter and 1-inch shank length, for a 2.25-inch overall length. The quick-change design allows for fast cartridge roll swaps without additional tooling. It is used by machinists, fabricators, and maintenance technicians for deburring, blending, and finishing in tight or contoured areas.

This mandrel is suited for light metalworking, automotive, and general fabrication applications where abrasive cartridge rolls are required. The quick-change feature makes it practical in production environments where multiple grit sizes are cycled through during a single job. It is commonly used in hand-held die grinder setups for interior bore work, slot finishing, and weld blending.

Installation Notes

Installation is performed by machinists or fabricators using a standard die grinder collet wrench. Ensure the die grinder is fully powered off and disconnected from the air supply or power source before changing mandrels or cartridge rolls. Do not exceed the RPM rating of the abrasive cartridge roll being used. Inspect the mandrel pilot for wear before each use and replace if deformation is visible.
