It uses 3M Precision-Shaped Grain, a ceramic abrasive technology that fractures along consistent planes to maintain sharp cutting edges throughout the disc life. The poly-cotton X-weight backing resists fraying and tearing, making this disc a reliable choice for edge work where standard discs tend to break down quickly. At 40 grit, it is suited for rapid stock removal and surface preparation. The Roloc threaded attachment system allows for fast disc changes without tools. Licensed tradespeople and fabricators working on metal surfaces are the primary installers.\u003c\/p\u003e\u003cp\u003eThis disc is designed for use with Roloc-compatible angle grinders and disc pads rated for 4-inch accessories. At a maximum speed of 12000 RPM, it is appropriate for high-speed grinder applications in fabrication shops, field metalwork, and maintenance operations. Typical applications include weld blending, edge chamfering, deburring, and surface conditioning on ferrous and non-ferrous metals. The evenly spaced grain pattern helps prevent loading when working on softer metals or coated surfaces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3M Precision-Shaped Grain maintains consistent cut rate and reduces heat buildup at the workpiece\u003c\/li\u003e\n\u003cli\u003eEvenly spaced grain layout allows debris to escape, resisting loading during use\u003c\/li\u003e\n\u003cli\u003eHeavy X-weight poly-cotton backing withstands edge contact without fraying or tattering\u003c\/li\u003e\n\u003cli\u003eRoloc threaded hub attachment enables fast, tool-free disc changes\u003c\/li\u003e\n\u003cli\u003e40 grit rating delivers aggressive stock removal for weld blending and surface prep\u003c\/li\u003e\n\u003cli\u003eRated to 12000 RPM for compatibility with standard high-speed angle grinders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Roloc-compatible 4-inch disc pads and angle grinders rated at or above 12000 RPM.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by tradespeople operating angle grinders in fabrication or field metalwork environments. Ensure the grinder is powered off and unplugged before attaching or removing the disc. Thread the Roloc hub onto a compatible backing pad until fully seated before operating. Do not exceed the rated speed of 12000 RPM, and always wear appropriate eye and face protection during operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Speed\u003c\/strong\u003e: 12000 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Roloc Threaded Hub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Poly-Cotton X-Weight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Precision-Shaped Ceramic Grain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 4.85 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 13.59 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 11.88 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 6.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7100077045\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344906715442,"sku":"7100077045","price":375.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310533439.jpg?v=1782045109","url":"https:\/\/voomisupply.com\/products\/3m-7100077045-cubitron-ii-roloc-disc-4-inch-40-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
