Value Collection CR-1 Cartridge Roll Mandrel Quick Change

Product Description

The VALUE COLLECTION CR-1 is a cartridge roll mandrel designed to hold and drive cartridge rolls in rotary grinding and finishing operations. The mandrel features a 5/64-inch pilot diameter with a 1-inch pilot length, a 1/8-inch shank diameter with a 1-inch shank length, and a 3-inch overall length. The quick-change design allows for fast cartridge roll swaps without removing the mandrel from the tool, reducing downtime during deburring, blending, or surface prep work. This type of mandrel is a staple in metalworking shops and field maintenance settings where die grinders are used for finishing tasks.

The CR-1 mandrel is suited for use in portable die grinders and similar rotary tools in light industrial, maintenance, and fabrication environments. It is used when cleaning up welds, deburring drilled holes, or finishing tight contours and inside radii where larger abrasive tools cannot reach. The quick-change feature is particularly useful in production or repetitive finishing operations where multiple grit sizes are needed in sequence.
