Built on a Y-weight 2-ply polyester backing, this disc is rated rigid and handles up to 30,000 RPM, making it suitable for fast, high-contact grinding passes. The 40-grit aluminum oxide abrasive grain features a special coating that reduces loading and extends disc life on moderately demanding applications. It attaches via a Power-Lock Type P (Type I) system and is sized for handheld disc sanders used in fabrication and maintenance work.\u003c\/p\u003e\n\u003cp\u003eThis disc is intended for trade and industrial use in metal fabrication, welding, and surface preparation. It performs on a broad range of materials including 300 and 400 Series Stainless Steel, aluminum, brass, bronze, hard and soft carbon steels, and titanium. The coarse 40-grit cut rate makes it well suited for weld seam blending, scale removal, and initial surface conditioning where speed of cut matters more than finish quality. It is compatible with handheld disc sanders equipped with a TP or Type I quick-change interface.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e40-grit aluminum oxide abrasive for fast stock removal on metal\u003c\/li\u003e\n  \u003cli\u003eY-weight 2-ply polyester backing provides rigid support and durability\u003c\/li\u003e\n  \u003cli\u003eSpecial grain coating reduces loading and extends disc life\u003c\/li\u003e\n  \u003cli\u003eRated to 30,000 RPM for use with handheld disc sanders\u003c\/li\u003e\n  \u003cli\u003ePower-Lock Type P (Type I) attachment system for tool-free disc changes\u003c\/li\u003e\n  \u003cli\u003eCompatible with 300 and 400 Series Stainless Steel, aluminum, brass, bronze, carbon steels, and titanium\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with handheld disc sanders equipped with a TP or Type I quick-change attachment system.

Ensure the tool is powered off and disconnected from its power source before mounting or removing the disc. Verify the tool spindle speed does not exceed the 30,000 RPM maximum rating of the disc before operation. Inspect the disc for damage before each use and discard any disc that shows cracking, fraying, or delamination.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 1.5 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlexibility\u003c\/strong\u003e: Rigid\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuick-Change Compatibility\u003c\/strong\u003e: TP (Type I)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttaching System\u003c\/strong\u003e: Type P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 30,000\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\u003eWeight\u003c\/strong\u003e: 0.001 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31191506\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: 69957399763\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT","offers":[{"title":"Default Title","offer_id":51557858672946,"sku":"69957399763","price":5614.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6ede3f96f6e79cc06db4dcac6b84a387.jpg?v=1786396668","url":"https:\/\/voomisupply.com\/products\/merit-abrasives-69957399763-quick-change-disc-40-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
