Built around aluminum oxide abrasive in a coarse grade, the disc delivers consistent material removal and surface preparation performance. At 4.5 inches in diameter, it mounts via a hook and loop backing system for fast pad changes without tools. Rated to 13,000 RPM, this disc is suited for use with right-angle grinders and random orbital sanders. It belongs to the 3M SE-DH series and carries ACRS certification.\u003c\/p\u003e\n\u003cp\u003eThis disc is commonly used by fabricators, welders, and maintenance technicians for weld blending, rust removal, and coarse surface preparation on ferrous and non-ferrous substrates. The non-woven construction provides a conformable, flexible cutting action that follows contours and irregular surfaces without loading as quickly as coated abrasive alternatives. Coarse grade stock removal makes it a first-pass tool in multi-step finishing sequences. Suitable for both bench and field service work in industrial, commercial, and light manufacturing environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive in coarse grade for aggressive stock removal\u003c\/li\u003e\n  \u003cli\u003eNon-woven construction conforms to curved and irregular surfaces\u003c\/li\u003e\n  \u003cli\u003eHook and loop backing enables tool-free disc changes on compatible pads\u003c\/li\u003e\n  \u003cli\u003eRated to 13,000 RPM for use with standard right-angle grinders\u003c\/li\u003e\n  \u003cli\u003eFlexible disc body reduces gouging and chatter on contoured workpieces\u003c\/li\u003e\n  \u003cli\u003eBrown disc color; no vacuum holes, keeping the face fully active\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with hook and loop backup pads sized for 4.5-inch discs on right-angle grinders and random orbital sanders.

Press the disc firmly onto the hook and loop backup pad to ensure full engagement before powering the tool. Always confirm the tool and pad assembly RPM rating equals or exceeds the disc maximum of 13,000 RPM. Inspect the disc for tears or damage before each use and discard any disc that shows signs of delamination or core separation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Non-Woven\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Type\u003c\/strong\u003e: Hook and Loop\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 13,000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Brown\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVacuum Holes\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlexible\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SE-DH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertification\u003c\/strong\u003e: ACRS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.15 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 7100136779\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51718781042994,"sku":"7100136779","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/987a7f49733c08e0f678ea2b05f66b1c_c720c8d8-339b-4c8b-ad97-5442278771fa.jpg?v=1788555535","url":"https:\/\/voomisupply.com\/products\/3m-7100136779-hook-loop-abrasive-disc-4-5-in-aluminum-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
