The pilot diameter measures 5\/16 inches with a pilot length of 2 inches, providing secure cartridge roll retention during operation. The shank measures 1\/4 inches in diameter and 1 inch in length, compatible with standard die grinders, drill presses, and rotary tools. Overall assembly length is 4 inches. Machinists, tool and die workers, and metalworking professionals use this mandrel for interior bore finishing, weld cleanup, and contour blending tasks where consistent abrasive contact is required.\u003c\/p\u003e\n\u003cp\u003eThis mandrel is suited for use in metalworking, fabrication, and maintenance environments where cartridge rolls are the preferred abrasive form. It is commonly used in both shop and field settings for deburring tube bores, finishing weld joints, and smoothing contoured surfaces in steel, aluminum, and similar materials. The quick-change design reduces changeover time when swapping between cartridge roll grits during multi-step finishing operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16 inch pilot diameter accepts standard cartridge rolls of matching bore size\u003c\/li\u003e\n  \u003cli\u003e2 inch pilot length provides extended reach into bores and contoured workpieces\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch shank diameter fits most die grinders and rotary tool chucks\u003c\/li\u003e\n  \u003cli\u003e4 inch overall length suits a range of access configurations\u003c\/li\u003e\n  \u003cli\u003eQuick-change design speeds cartridge roll swaps during multi-grit finishing sequences\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement mandrel for use with standard 5\/16 inch bore cartridge rolls in die grinders and rotary tools equipped with a 1\/4 inch chuck or collet.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by metalworking and machining professionals using standard die grinders or rotary tools.
