Value Collection CR-16-4 Cartridge Roll Mandrel

Product Description

The VALUE COLLECTION CR-16-4 is a cartridge roll mandrel designed to hold and drive abrasive cartridge rolls in rotary power tools such as die grinders and drill presses. The mandrel features a 3/16 inch pilot diameter with a 1 inch pilot length, paired with a 1/4 inch shank diameter and a 2-1/4 inch shank length, giving it a 4 inch overall length. The quick-change design allows for fast cartridge roll swaps without additional tooling. It is a standard accessory used by machinists, metalworkers, and maintenance technicians for deburring, blending, and surface finishing work.

This mandrel is suited for bench or portable rotary tool applications where cartridge rolls are used on metal, composite, or similar workpiece materials. Typical use cases include weld blending, port work, and contour finishing in fabrication shops, maintenance facilities, and production environments. The 1/4 inch shank fits the collets and chucks found on most standard die grinders and rotary tools.
