Built on a cloth backing with aluminum oxide grain at 120 grit, this roll delivers consistent fine-grade cutting action throughout its working life. At 0.5 inches in diameter, it mounts on a mandrel and runs at up to 24,000 RPM on die grinders and rotary tools. Metalworkers, fabricators, and maintenance technicians use it for edge work, weld blending, and surface prep on steel and other hard metals.\u003c\/p\u003e\n\u003cp\u003eThis cartridge roll is suited for precision finishing applications in metal fabrication shops, aerospace maintenance, tool-and-die work, and general industrial grinding. The fine 120 grit is appropriate for final deburring passes, light stock removal, and surface conditioning where a smoother finish is required after coarser grinding steps. The cloth backing provides flexibility to conform to curved or irregular surfaces without tearing under rotary load.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e120 grit aluminum oxide abrasive for fine-grade material removal and finishing\u003c\/li\u003e\n  \u003cli\u003eCloth backing offers flexibility for contoured and internal surface work\u003c\/li\u003e\n  \u003cli\u003e0.5 inch diameter fits standard small-bore mandrels for die grinders\u003c\/li\u003e\n  \u003cli\u003eRated to 24,000 RPM for use with high-speed rotary tools\u003c\/li\u003e\n  \u003cli\u003eStraight cartridge profile for consistent contact in slots, holes, and channels\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on standard cartridge roll mandrels accepting a 0.5 inch diameter straight cartridge roll.
