Value Collection CR-9-6 Cartridge Roll Mandrel

Product Description

The VALUE COLLECTION CR-9-6 is a cartridge roll mandrel designed to hold and drive cartridge rolls during grinding, deburring, and surface finishing operations. The mandrel features a 0.125-inch pilot diameter and a 1-inch pilot length for secure cartridge roll retention. The 0.25-inch shank diameter and 4.5-inch shank length allow it to be chucked into standard die grinders and rotary tools. Overall length is 6 inches. The quick-change design speeds up cartridge roll swaps during continuous finishing work, reducing downtime between abrasive changes.

This mandrel is used in metal fabrication, maintenance, and repair applications where cartridge rolls are the preferred abrasive format. Typical scenarios include deburring drilled or machined holes, blending welds, and finishing internal or contoured surfaces. It is suited for use in handheld die grinders in both shop and field environments. Machinists, fabricators, and maintenance technicians are the primary users.
