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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/64-inch pilot diameter sized for standard small-bore cartridge rolls\u003c\/li\u003e\n  \u003cli\u003e1-inch pilot length provides adequate abrasive contact and support\u003c\/li\u003e\n  \u003cli\u003e1\/8-inch shank diameter fits common die grinder collets\u003c\/li\u003e\n  \u003cli\u003eQuick-change design speeds up cartridge roll replacement\u003c\/li\u003e\n  \u003cli\u003e3-inch overall length for reach into confined work areas\u003c\/li\u003e\n  \u003cli\u003eSold as a single-piece unit, compatible with standard cartridge roll abrasives\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard mandrel for use with cartridge roll abrasives in rotary die grinders accepting a 1\/8-inch shank.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists, tool and die technicians, or maintenance professionals using a standard die grinder.
