Value Collection CR-2E Cartridge Roll Mandrel Quick Change

Product Description

The VALUE COLLECTION CR-2E is a quick-change cartridge roll mandrel designed to hold abrasive cartridge rolls for use in die grinders and rotary tools. It features a 3/32-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 that fits directly into collet-style tool chucks. Overall length is 2-3/4 inches. The quick-change design allows roll swaps without removing the shank from the tool, reducing downtime during grinding, deburring, and finishing operations on metal or composite surfaces.

This mandrel is suited for metalworking, fabrication, and maintenance applications where cartridge rolls are used for internal diameter finishing, port grinding, weld blending, and surface preparation. It is a standard toolroom and job-shop consumable used by machinists, tool-and-die technicians, pipefitters, and maintenance mechanics who run die grinders at benchtop or in-field. Compatible with abrasive cartridge rolls sized to the 3/32-inch pilot specification.

Installation Notes

Installation is performed by machinists or general maintenance technicians using standard collet wrenches. Power down and disconnect the die grinder from its air supply or electrical source before installing or changing the mandrel or cartridge roll. Ensure the shank is fully seated and the collet nut is snug before operating the tool. Inspect the mandrel for wear or runout before each use and replace if deformation is visible.
