Built around 3M Precision-Shaped Grain, the disc cuts faster and outlasts conventional aluminum oxide and alumina zirconia flap discs. The 4.5-inch diameter disc runs at a maximum of 13300 RPM and carries a 40-grit rating, making it well-suited for heavy stock removal, weld grinding, and beveling. Individual flaps wear away progressively, continuously exposing fresh abrasive mineral so cut rate stays consistent from the first pass to the last.\u003c\/p\u003e\u003cp\u003eThis disc is used across fabrication shops, maintenance facilities, and job sites where versatile surface work is required. Common applications include weld grinding, weld beveling, and surface preparation on carbon steel and stainless steel workpieces. The Type 27 depressed-center profile keeps the grinding angle low and controlled, which is particularly useful when working in tight areas or on flat stock. The 40-grit cut level handles initial passes on rough welds and heavy scale before transitioning to finish work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3M Precision-Shaped Grain cuts faster and lasts longer than conventional aluminum oxide and alumina zirconia abrasive grain\u003c\/li\u003e\n\u003cli\u003eProgressive flap breakdown exposes fresh mineral continuously, maintaining consistent cut rate throughout disc life\u003c\/li\u003e\n\u003cli\u003e40 grit rating suited for weld grinding, beveling, and aggressive surface preparation\u003c\/li\u003e\n\u003cli\u003eType 27 depressed-center profile for low-angle grinding on flat and contoured surfaces\u003c\/li\u003e\n\u003cli\u003eRated to 13300 RPM for use with standard 4.5-inch angle grinders\u003c\/li\u003e\n\u003cli\u003eCompatible with carbon steel, stainless steel, and other heat-sensitive alloys\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 4.5-inch angle grinders rated at or above 13300 RPM.

Always power down and unplug or lock out the grinder before mounting or removing the disc. Verify that the grinder's rated RPM meets or exceeds the disc's maximum RPM rating before use. Inspect the disc for damage before each use and never operate a cracked or delaminated flap disc.\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\u003eGrit\u003c\/strong\u003e: 40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Type\u003c\/strong\u003e: Type 27 (T27)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Speed\u003c\/strong\u003e: 13300 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Coated Flap Disc with Precision-Shaped Grain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 8.4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 5.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 5.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.603 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 638060298836\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: 7100180139\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344513532210,"sku":"7100180139","price":107.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310519470.jpg?v=1782036723","url":"https:\/\/voomisupply.com\/products\/3m-7100180139-flap-disc-40-grit-4-5-inch-type-27-13300-rpm","provider":"Voomi Supply","version":"1.0","type":"link"}
