It features a 40-grit aluminum oxide abrasive bonded to a rigid Y-weight 2-ply polyester backing, delivering a faster cut rate and extended disc life compared to lighter-backed alternatives. The disc attaches via a Power-Lock Type P quick-change system and is rated to 20,000 RPM. At 3 inches in diameter, it mounts to handheld disc sanders used by metal fabricators, pipefitters, welders, and maintenance technicians working on demanding material removal tasks.\u003c\/p\u003e\n\u003cp\u003eThis disc is suited for coarse-grit applications in fabrication shops, field repair work, and maintenance environments where fast stock removal is required. The aluminum oxide grain and special surface coating are optimized for use on 300 series stainless steel, 400 series stainless steel, aluminum, brass, bronze, hard carbon steels, soft carbon steels, and titanium. The rigid polyester backing maintains consistent contact on flat and moderately contoured surfaces during weld blending and surface prep operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e40-grit coarse aluminum oxide abrasive for rapid stock removal and weld blending\u003c\/li\u003e\n  \u003cli\u003eY-weight 2-ply polyester backing provides rigidity and durability under load\u003c\/li\u003e\n  \u003cli\u003eSpecial grain coating extends disc life and maintains cut rate in moderately demanding applications\u003c\/li\u003e\n  \u003cli\u003ePower-Lock Type P quick-change attachment system for fast disc swaps without tools\u003c\/li\u003e\n  \u003cli\u003eRated to 20,000 RPM for use with standard handheld disc sanders\u003c\/li\u003e\n  \u003cli\u003eCompatible with a broad range of ferrous and non-ferrous metals including stainless, titanium, and aluminum\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with handheld disc sanders equipped with a Power-Lock Type P quick-change arbor.

Verify the spindle speed of the tool does not exceed the 20,000 RPM disc rating before operation. Inspect the disc for damage or delamination before each use and replace immediately if defects are found. Follow applicable ANSI and OSHA abrasive wheel safety standards when mounting and operating grinding and sanding discs.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\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: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Polyester\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Weight\u003c\/strong\u003e: Y-weight 2-ply\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlexibility\u003c\/strong\u003e: Rigid\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttaching System\u003c\/strong\u003e: Power-Lock Type P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 20,000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Brown\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R766\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMachine Compatibility\u003c\/strong\u003e: Handheld Disc Sander\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.021 pounds\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: MERIT ABRASIVES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 69957399787\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT","offers":[{"title":"Default Title","offer_id":51558127960370,"sku":"69957399787","price":6766.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6432a3dadbf782619c226973f02e8a03.jpg?v=1786404203","url":"https:\/\/voomisupply.com\/products\/merit-abrasives-69957399787-quick-change-disc-40-grit-3-in","provider":"Voomi Supply","version":"1.0","type":"link"}
