Value Collection CR-2 Cartridge Roll Mandrel Quick Change

Product Description

The VALUE COLLECTION CR-2 is a cartridge roll mandrel designed to hold and drive cartridge rolls during deburring, blending, and finishing operations on metal and other hard surfaces. The mandrel features a 3/32-inch pilot diameter with a 1-inch pilot length, accepting standard cartridge rolls for secure mounting. The shank measures 1/8 inch in diameter and 1 inch in length, with an overall length of 3 inches. A quick-change design allows for efficient roll swaps without removing the mandrel from the rotary tool or die grinder, reducing downtime during grinding and finishing work.

This mandrel is suited for use in metal fabrication shops, maintenance operations, and surface prep applications where cartridge rolls are the abrasive of choice. It mounts into die grinders, straight grinders, or flexible shaft tools that accept a 1/8-inch shank. Typical applications include weld blending, edge deburring, port matching, and contour finishing in both production and repair environments. The quick-change feature is particularly useful in high-volume finishing work where roll changes are frequent.
