The mandrel measures 3\/16 inch pilot diameter by 1 inch pilot length by 1\/4 inch shaft diameter, giving it a compact, precise fit for compatible abrasive cartridge rolls. It is used with rotary tools, die grinders, and similar power tools found in metal fabrication, maintenance, and finishing applications. Installation and use are straightforward for machinists, fabricators, and finishing technicians working with standard cartridge roll abrasives.\u003c\/p\u003e\n\u003cp\u003eThis mandrel is suited for use in metal fabrication shops, maintenance facilities, and production finishing environments where cartridge rolls are used to work inside diameters, contoured surfaces, or tight access areas. The screw-type drive mechanism holds the cartridge roll firmly under load, reducing slippage during aggressive material removal or blending passes. It is sold individually and is appropriate for both production and maintenance settings requiring consistent abrasive performance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eScrew-type design securely locks cartridge rolls in place during operation\u003c\/li\u003e\n  \u003cli\u003ePilot diameter: 3\/16 inch; pilot length: 1 inch; shaft diameter: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch shaft fits standard die grinder and rotary tool collets\u003c\/li\u003e\n  \u003cli\u003eCompact dimensions allow access to tight areas and contoured surfaces\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.06 pounds for reduced operator fatigue during extended use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with cartridge rolls having a 3\/16 inch bore, compatible with standard 1\/4 inch collet die grinders and rotary power tools used in grinding and finishing applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by fabricators or finishing technicians using a standard 1\/4 inch collet die grinder or rotary tool. Power down and disconnect the tool from its air or electrical supply before threading the cartridge roll onto the mandrel or inserting the mandrel into the collet. Ensure the cartridge roll is fully seated and the screw mechanism is tightened securely before resuming operation.
