Built around 3M Precision-Shaped Grain abrasive technology, the disc delivers a fast cut rate and extended service life compared to conventional abrasive grain. At 4.5 inches in diameter and 40 grit, it removes material aggressively while leaving a surface ready for coating or further finishing. Fabricators, welders, and metalworking professionals use this disc on right-angle grinders for weld leveling, light deburring, and pre-paint surface prep on mild steel and stainless steel.\u003c\/p\u003e\u003cp\u003eThis flap disc is suited for medium-duty metalworking applications in fabrication shops, manufacturing environments, and field welding operations. It performs well on flat surfaces and contoured profiles alike, making it a practical choice for weld seam leveling and blending. The 40-grit designation targets aggressive stock removal while still allowing reasonable control over the finished surface. It is particularly effective on stainless steel where gouge resistance and surface finish quality are critical requirements before inspection or coating.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3M Precision-Shaped Grain abrasive delivers fast cutting and extended disc life\u003c\/li\u003e\n\u003cli\u003eType 29 conical flap design suits both flat and contoured surface grinding\u003c\/li\u003e\n\u003cli\u003ePoly-cotton backing provides controlled, even wear under medium unit pressure\u003c\/li\u003e\n\u003cli\u003eIndividual flaps break down progressively, exposing fresh mineral for consistent cut rate throughout disc life\u003c\/li\u003e\n\u003cli\u003eProduces less gouging than fiber discs and bonded abrasive wheels\u003c\/li\u003e\n\u003cli\u003eEffective on mild steel and stainless steel for weld leveling and pre-paint surface preparation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on right-angle grinders accepting 4.5-inch diameter Type 29 flap discs.

Verify the grinder's maximum RPM rating meets or exceeds the disc's rated speed before mounting. Always inspect the disc for damage before use and confirm the backing plate and hardware are properly secured. Wear appropriate PPE including eye protection and gloves when operating angle grinders with abrasive discs.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\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 29 (Right Angle)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Grain\u003c\/strong\u003e: 3M Precision-Shaped Grain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Poly-cotton\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 5.366 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 8.88 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 5.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 6.13 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 051141556449\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: 7010363306\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344671179058,"sku":"7010363306","price":154.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310533756.jpg?v=1782039856","url":"https:\/\/voomisupply.com\/products\/3m-7010363306-flap-disc-40-grit-4-5-inch-type-29","provider":"Voomi Supply","version":"1.0","type":"link"}
