Value Collection CR-13 Cartridge Roll Mandrel

Product Description

The VALUE COLLECTION CR-13 is a quick-change cartridge roll mandrel designed to hold abrasive cartridge rolls during grinding, deburring, and surface blending operations. The mandrel features a 3/16-inch pilot diameter and 3/4-inch pilot length that accept standard cartridge rolls, while the 1/8-inch shank diameter seats securely in a die grinder, drill, or rotary tool. Overall length is 2.5 inches. The quick-change design allows fast roll swaps without removing the shank from the tool, reducing downtime on production or maintenance work.

This mandrel is suited for metalworking and fabrication tasks where cartridge rolls are used to blend welds, remove burrs, refine inside diameters, or prep surfaces before coating. It is commonly used by machinists, metal fabricators, maintenance technicians, and tool-and-die workers in both shop and field settings. The 1/8-inch shank fits standard collets and chucks found on most die grinders and high-speed rotary tools.
