Value Collection CR-16 Cartridge Roll Mandrel Quick Change

Product Description

The VALUE COLLECTION CR-16 is a cartridge roll mandrel designed to mount and drive abrasive cartridge rolls in rotary tool applications. 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 1-1/4-inch shank length for a total overall length of 3 inches. The quick-change design allows for fast cartridge roll swaps without removing the mandrel from the tool spindle, reducing downtime during grinding, blending, and deburring operations. It is installed by machinists, tool and die workers, and metalworking fabricators.

This mandrel is suited for use in straight die grinders, drill presses, and similar rotary tools where abrasive cartridge rolls are required for internal diameter finishing, port blending, weld cleanup, and surface preparation on metal workpieces. The quick-change interface makes it practical in production environments where multiple grit sizes are cycled through a single operation.

Key Features

• 3/16-inch pilot diameter accommodates standard cartridge rolls of matching bore size
• 1-inch pilot length provides sufficient roll engagement for controlled material removal
• 1/4-inch shank diameter fits standard die grinder and rotary tool collets
• Quick-change design enables rapid cartridge roll replacement during operation
• 3-inch overall length suits typical straight die grinder reach requirements

Compatibility

Designed as an OEM-style replacement mandrel for use with standard abrasive cartridge rolls featuring a 3/16-inch bore, in straight die grinders and rotary tools accepting a 1/4-inch shank.

Installation Notes

Installation is performed by machinists or metalworking fabricators using a standard collet wrench to secure the 1/4-inch shank in the tool spindle. Always power down and disconnect the tool from its power source before mounting or changing cartridge rolls on the mandrel. Ensure the cartridge roll is fully seated on the pilot before operation and that shank runout is within acceptable limits for the application.
