Built on a Type 27 (T27) flat-profile hub, it carries alumina zirconia mineral flaps bonded to heavyweight polyester backing. The alumina zirconia grain cuts faster than standard aluminum oxide across carbon steel, stainless, and other metal types, and it is paired with a grinding aid that extends cool cutting under sustained load. At 4.5 inches in diameter with an 80-grit cut and a 13,300 RPM max speed rating, this disc handles aggressive stock removal while leaving a blended finish in the same pass. Metal fabricators, welders, and pipefitters use it where a two-step grind-then-blend workflow would otherwise be required.\u003c\/p\u003e\u003cp\u003eThis flap disc is suited to heavy-duty metalworking tasks including weld removal, sharp-edge deburring, and beveling on structural steel, pipe, and plate. The T27 flat-face geometry keeps the disc low-profile against workpiece surfaces, making it effective on flat stock and inside tight weld seams. It is intended for use on angle grinders rated for 4.5-inch accessories at or above 13,300 RPM. Each disc is sold individually.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlumina zirconia mineral with grinding aid delivers faster cut rates than aluminum oxide on all common metal types\u003c\/li\u003e\n\u003cli\u003eCombined grinding and blending action completes surface prep in a single disc pass\u003c\/li\u003e\n\u003cli\u003eHeavyweight polyester-backed flaps resist breakdown under high clamping pressure during sharp-edge work and beveling\u003c\/li\u003e\n\u003cli\u003eType 27 flat-profile hub suits flat stock, plate, and flush weld applications\u003c\/li\u003e\n\u003cli\u003e13,300 RPM max speed rating compatible with standard 4.5-inch angle grinders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement flap disc for 4.5-inch angle grinders accepting Type 27 discs at a maximum of 13,300 RPM.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eDisc mounting and removal must be performed with the grinder unplugged or the power source locked out per OSHA and tool manufacturer requirements. Verify the grinder guard is properly installed and that the arbor nut is seated and torqued before operation. Inspect the disc for visible damage before each use and do not exceed the rated RPM printed on the disc hub. Metal grinding generates sparks and debris — ensure the work area is clear of flammable materials before use.\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: 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Type\u003c\/strong\u003e: Type 27 (T27)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Speed\u003c\/strong\u003e: 13,300 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Mineral\u003c\/strong\u003e: Alumina Zirconia\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Heavyweight Polyester\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.32 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\u003eSold As\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: 7010308898\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51345443127602,"sku":"7010308898","price":132.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310533326.jpg?v=1782058331","url":"https:\/\/voomisupply.com\/products\/3m-7010308898-flap-disc-4-5-in-80-grit-type-27-13300-rpm","provider":"Voomi Supply","version":"1.0","type":"link"}
