It uses aluminum oxide abrasive grain bonded to a rigid, X-weight, 2-ply cloth and polyester backing for consistent cut rate and durability under load. The 40-grit coarse grade removes stock quickly, making it well suited for deburring, surface conditioning, and weld cleanup. The Power-Lock Type 3 (TR\/Type III) attachment system snaps directly onto compatible quick-change mandrels, allowing fast disc swaps without tools. Rated to 20,000 RPM, this disc handles high-speed handheld disc sanders without delamination or disc failure under normal operating conditions.\u003c\/p\u003e\n\u003cp\u003eThis disc is rated for use on a broad range of metals including 300 series stainless, 400 series stainless, aluminum, brass, bronze, hard carbon steels, soft carbon steels, and titanium. It is intended for handheld disc sander applications in fabrication shops, maintenance facilities, and field metalwork environments. Typical tasks include deburring cut edges, cleaning weld zones, and detailing stainless steel and non-ferrous metal surfaces. The coarse 40-grit grade removes material efficiently before stepping to finer finishing grits.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e40-grit coarse aluminum oxide abrasive for fast stock removal\u003c\/li\u003e\n  \u003cli\u003eX-weight, 2-ply cloth and polyester backing rated for rigid, high-torque applications\u003c\/li\u003e\n  \u003cli\u003ePower-Lock Type 3 (TR\/Type III) quick-change attachment for tool-free disc changes\u003c\/li\u003e\n  \u003cli\u003e20,000 RPM maximum speed rating for compatibility with standard handheld disc sanders\u003c\/li\u003e\n  \u003cli\u003eRated for use on stainless steel, aluminum, brass, bronze, carbon steels, and titanium\u003c\/li\u003e\n  \u003cli\u003eSeries R766 construction with brown disc color and black button\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with handheld disc sanders equipped with a TR (Type III) or Type R quick-change mandrel.

Confirm the mandrel and tool are rated for at least 20,000 RPM before mounting the disc. Inspect the disc for damage before each use and do not use a disc that shows cracking, delamination, or backing separation. Always wear appropriate eye and face protection and follow ANSI B7.1 safety standards for abrasive disc operation.\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\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\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 Type\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Cloth and Polyester\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Weight\u003c\/strong\u003e: Y (X-weight, 2-ply)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlexibility\u003c\/strong\u003e: Rigid\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 20,000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachment System\u003c\/strong\u003e: Power-Lock Type 3 \/ TR (Type III) \/ Type R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Brown\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eButton Color\u003c\/strong\u003e: Black\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\u003eMinimum Order Quantity\u003c\/strong\u003e: 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.021 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: 69957399719\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT","offers":[{"title":"Default Title","offer_id":51557262065970,"sku":"69957399719","price":6766.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/194091c2a9e91f93dafb798bb64f5a2a.jpg?v=1786384844","url":"https:\/\/voomisupply.com\/products\/merit-abrasives-69957399719-quick-change-disc-40-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
