Built on a cloth backing with a ceramic abrasive grain at 120 grit, this roll delivers fine-grade cutting action suited for deburring, blending, and surface finishing on metal components. It runs at a maximum of 18,000 RPM, making it compatible with high-speed rotary tools and die grinders. At 3\/8 inch in diameter, the roll fits into restricted access points where flat abrasives cannot reach. Metalworkers, fabricators, and tool-and-die technicians are the primary installers and users of this consumable.\u003c\/p\u003e\u003cp\u003eThis cartridge roll is used in metalworking and fabrication shops for finishing bores, slots, weld seams, and internal contours on steel, stainless, and other hard metals. The ceramic grain self-sharpens during use, maintaining cut rate longer than aluminum oxide alternatives. Typical applications include die finishing, mold polishing prep, and deburring of machined parts where a fine surface finish is required before final inspection or coating.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic abrasive grain self-sharpens for extended service life on hard metals\u003c\/li\u003e\n\u003cli\u003e120 grit fine grade for blending and pre-finishing operations\u003c\/li\u003e\n\u003cli\u003eCloth backing provides flexibility and durability in contoured work\u003c\/li\u003e\n\u003cli\u003e3\/8 inch diameter fits die grinders and rotary tools accessing tight bores and slots\u003c\/li\u003e\n\u003cli\u003e18,000 RPM maximum rated speed compatible with standard pneumatic die grinders\u003c\/li\u003e\n\u003cli\u003eStraight roll geometry for consistent, uniform contact in cylindrical or slotted surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use consumable for standard mandrel-mounted rotary tool setups accepting 3\/8 inch diameter straight cartridge rolls.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCartridge rolls are installed by qualified metalworkers or machinists using a compatible mandrel mounted in a die grinder or rotary tool. Verify the tool spindle speed does not exceed the 18,000 RPM maximum rating before operation. Inspect the roll for damage before mounting and ensure the mandrel nut is secured before powering the tool. Always wear appropriate eye protection and follow shop safety protocols when operating abrasive tools.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 120\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Cloth\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 18,000 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MERIT ABRASIVES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66261194398\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT","offers":[{"title":"Default Title","offer_id":51562419454258,"sku":"66261194398","price":138.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7b4a9a6b10ec090670083afeedeeed55.jpg?v=1786476745","url":"https:\/\/voomisupply.com\/products\/merit-abrasives-66261194398-straight-cartridge-roll-120-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
