Part of the Cool Cut XX series, this disc uses a ceramic abrasive grain bonded with a resinoid bond to a fiber backing, delivering fast stock removal with a coarse 50-grit cut. It is rated to a maximum of 13,300 RPM and is designed for use with standard angle grinders equipped with an arbor hole attachment. Metalworking professionals, fabricators, and pipefitters rely on this type of disc for weld grinding, surface preparation, and edge work where consistent cut rate and disc longevity matter.\u003c\/p\u003e\u003cp\u003eThis disc is suited for heavy-duty grinding applications in fabrication shops, structural steel work, and maintenance environments. The ceramic grain construction supports use on carbon steel, stainless steel, and other hard metals where high material removal rates are required. The fiber backing provides rigidity and durability under sustained pressure. At 50 grit, it is positioned for coarse stock removal rather than finishing work. The orange disc color is specific to the Cool Cut XX series for quick visual identification on the job.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic abrasive grain for high cut rate and extended disc life on metal\u003c\/li\u003e\n\u003cli\u003eCoarse 50-grit provides aggressive stock removal for weld grinding and surface prep\u003c\/li\u003e\n\u003cli\u003eResinoid bond with fiber backing delivers rigidity and durability under load\u003c\/li\u003e\n\u003cli\u003eArbor hole attachment fits standard angle grinders\u003c\/li\u003e\n\u003cli\u003eMaximum operating speed of 13,300 RPM\u003c\/li\u003e\n\u003cli\u003eCool Cut XX series construction designed to reduce heat buildup during grinding\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with angle grinders accepting a 4-1\/2-inch fiber disc with a 7\/8-inch arbor hole attachment.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis disc should be mounted and used by trained personnel following ANSI B7.1 and applicable shop safety standards. Always inspect the disc for damage before mounting and confirm the grinder RPM rating meets or exceeds the disc maximum before operation. Wear appropriate PPE including eye protection, gloves, and a face shield. Never exceed the 13,300 RPM maximum operating speed marked for this disc.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 4-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Fiber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resinoid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Arbor Hole\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 13,300\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Orange\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Cool Cut XX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.6 inches x 4.6 inches x 2.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.52 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WALTER SURFACE TECHNOLOGIES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 15X455\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":67907405971762,"sku":"15X455","price":102.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e57c024ff0a1646e911af72407241729.jpg?v=1791179044","url":"https:\/\/voomisupply.com\/products\/walter-surface-technologies-15x455-fiber-disc-50-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
