Measuring 4.5 inches in diameter with a 7\/8-inch arbor hole, it runs at a maximum of 13,300 RPM on a standard angle grinder. The 40-grit coarse abrasive and plastic backing make it well suited for heavy stock removal, weld blending, and surface conditioning on steel and stainless steel. The trimmable design allows the operator to expose fresh abrasive as the disc wears, extending usable life. Fabricators, pipefitters, and metal finishing technicians are the primary users of this product.\u003c\/p\u003e\u003cp\u003eThis flap disc is intended for use on angle grinders in both shop and field environments. Its Type 27 flat profile provides maximum surface contact during flat grinding and blending passes. The zirconia alumina abrasive grain self-sharpens under pressure, making it effective for sustained grinding on steel and stainless steel fabrication work, structural steel prep, and weld seam removal. The coarse 40-grit rating is appropriate for initial material removal rather than finish work. It is sold individually per package.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 27 flat-profile disc for flat grinding and blending on angle grinders\u003c\/li\u003e\n\u003cli\u003e40-grit coarse zirconia alumina abrasive for aggressive stock removal\u003c\/li\u003e\n\u003cli\u003eMaximum operating speed of 13,300 RPM\u003c\/li\u003e\n\u003cli\u003ePlastic backing provides durability and consistent flex during use\u003c\/li\u003e\n\u003cli\u003eTrimmable design exposes fresh abrasive as the disc wears\u003c\/li\u003e\n\u003cli\u003eRated for use on steel and stainless steel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with angle grinders accepting a 7\/8-inch arbor attachment.

Before mounting, confirm the tool's rated no-load RPM does not exceed the disc's 13,300 RPM maximum. Inspect the disc for damage before each use and never exceed the marked maximum speed. Follow ANSI B7.1 and applicable workplace safety standards when operating abrasive grinding wheels.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Hole Size\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlap Disc Type\u003c\/strong\u003e: Type 27\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 40\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: Zirconia Alumina\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: Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Arbor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 13,300\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Stainless Steel, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMachine Compatibility\u003c\/strong\u003e: Angle Grinder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrimmable\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 15-R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.032 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: 15R454\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":67907677520178,"sku":"15R454","price":197.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1cf501653845440a60113f619630c0d2.jpg?v=1791181003","url":"https:\/\/voomisupply.com\/products\/walter-surface-technologies-15r454-flap-disc-40-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
