Value Collection CR-28 Cartridge Roll Mandrel Quick Change

Product Description

The VALUE COLLECTION CR-28 is a quick-change cartridge roll mandrel designed to hold and drive cartridge rolls in rotary finishing, deburring, and surface conditioning applications. The pilot diameter measures 5/16 inches with a pilot length of 2 inches, providing secure cartridge roll retention during operation. The shank measures 1/4 inches in diameter and 1 inch in length, compatible with standard die grinders, drill presses, and rotary tools. Overall assembly length is 4 inches. Machinists, tool and die workers, and metalworking professionals use this mandrel for interior bore finishing, weld cleanup, and contour blending tasks where consistent abrasive contact is required.

This mandrel is suited for use in metalworking, fabrication, and maintenance environments where cartridge rolls are the preferred abrasive form. It is commonly used in both shop and field settings for deburring tube bores, finishing weld joints, and smoothing contoured surfaces in steel, aluminum, and similar materials. The quick-change design reduces changeover time when swapping between cartridge roll grits during multi-step finishing operations.
