It uses aluminum oxide grain bonded into a high-loft nylon and polyester non-woven web, delivering consistent cut with a smear-free finish. The Type R Power-Lock attaching system mounts the disc directly to compatible quick-change mandrels without tools. Rated to 20,000 RPM, the disc is graded Very Fine and suited to finish passes, light deburring, and surface prep where scratch pattern control matters. Clean Bond resin technology resists loading on soft and hard metals alike.\u003c\/p\u003e\u003cp\u003eThis disc is built for die grinders, inline grinders, straight grinders, and handheld disc sanders used in metal fabrication, aerospace prep, and maintenance grinding. Approved material applications include 300 and 400 series stainless steel, hard and soft carbon steels, tool steels, super alloys, titanium, and fiberglass or composite panels. The flexible non-woven construction conforms to contoured surfaces, making it useful for weld blending, pre-weld prep, and interpass cleaning where a rigid bonded disc would leave deep scratches.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide grain provides a higher cut rate than synthetic non-woven alternatives at Very Fine grade\u003c\/li\u003e\n\u003cli\u003eHigh-loft nylon fiber construction extends disc life compared to standard non-woven pads\u003c\/li\u003e\n\u003cli\u003eClean Bond resin technology delivers smear-free finishes on stainless and exotic alloys\u003c\/li\u003e\n\u003cli\u003eType R Power-Lock quick-change system for tool-free disc swaps on compatible mandrels\u003c\/li\u003e\n\u003cli\u003eFlexible polyester and nylon web backing conforms to curved and irregular surfaces\u003c\/li\u003e\n\u003cli\u003eRated to 20,000 RPM for use on high-speed die grinders and inline grinders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with die grinders, handheld disc sanders, inline grinders, and straight grinders equipped with a Type R quick-change mandrel.

Verify the mandrel and grinder are rated to at least 20,000 RPM before mounting the disc. Disconnect the tool from its power source or air supply before changing discs. Inspect the disc for tears or unraveling before each use and do not use a damaged disc.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Non-Woven\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Very Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 20,000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttaching System\u003c\/strong\u003e: Type R Power-Lock\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Polyester and Nylon Web\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Weight\u003c\/strong\u003e: Y\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexibility\u003c\/strong\u003e: Flexible\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eButton Color\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrimmable\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.028 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 25\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MERIT ABRASIVES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66254441300\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT","offers":[{"title":"Default Title","offer_id":51558590251314,"sku":"66254441300","price":91.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7994634389f4d5f1f9496dba2a6b92c0.jpg?v=1786415116","url":"https:\/\/voomisupply.com\/products\/merit-abrasives-66254441300-quick-change-disc-3-in-aluminum-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
