Value Collection CR-17-6 Cartridge Roll Mandrel

Product Description

The VALUE COLLECTION CR-17-6 is a quick-change cartridge roll mandrel designed to hold abrasive cartridge rolls for deburring, blending, and surface finishing operations. The mandrel features a 0.1875-inch pilot diameter and a 1.5-inch pilot length, accepting standard cartridge rolls for use in die grinders, drill presses, and similar rotary tools. The 0.25-inch shank diameter and 3.75-inch shank length provide solid tool holder engagement, while the 6-inch overall length (OAL) gives the reach needed for most internal or contoured surface work. Machinists, fabricators, and metalworkers use this mandrel for finishing bores, ports, and hard-to-reach areas where flat abrasive media cannot conform to the workpiece geometry.

This cartridge roll mandrel is suited for general metalworking and fabrication environments, including maintenance shops, job shops, and manufacturing facilities. It is compatible with cartridge rolls having a matching 0.1875-inch pilot bore and is used in applications such as weld blending, port matching, casting cleanup, and precision deburring. The quick-change design speeds up roll replacement during extended finishing runs, reducing downtime between abrasive changes.

Key Features

Compatibility

Designed for use with abrasive cartridge rolls having a 0.1875-inch pilot bore. Fits tool holders and collets accepting a 0.25-inch shank diameter, typical of standard die grinders and rotary tools used in metalworking applications.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the rotary tool or grinder is powered down and unplugged before mounting or removing the mandrel. Secure the shank firmly in the collet to the tool manufacturer's specified engagement depth before operating. Always confirm the abrasive cartridge roll is fully seated on the pilot before starting the spindle, and operate within the maximum RPM rating of both the mandrel and the abrasive roll.
