It uses aluminum oxide grain on a rigid, X-weight 2-ply polyester backing that resists tearing and maintains cut rate through extended use. The Type S Power-Lock attachment system seats and releases quickly without tools, keeping downtime low during disc changes. Rated to 20,000 RPM, it handles high-speed grinders safely. At 180 grit, it falls in the very fine range, making it well suited for deburring edges, cleaning weld seams, and finish detailing on metal surfaces. Licensed HVAC, fabrication, and metal finishing technicians working on precision components will find this disc size and grit combination practical for tight-clearance work.\u003c\/p\u003e\n\u003cp\u003eThis disc is designed for use on 300 series stainless steel, brass, bronze, hard carbon steels, soft carbon steels, and titanium. The aluminum oxide abrasive performs consistently across this range of materials, making it a shop staple where multiple alloys are worked in a single session. The 3-inch diameter fits compact handheld disc sanders commonly used in HVAC fabrication, plumbing rough-in, and general metal prep. The brown coated cloth face and rigid backing resist loading on softer metals and maintain a consistent scratch pattern on harder alloys.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e180 grit aluminum oxide abrasive for very fine deburring, cleaning, and detailing\u003c\/li\u003e\n  \u003cli\u003eRigid X-weight 2-ply polyester backing resists tearing under load\u003c\/li\u003e\n  \u003cli\u003eType S Power-Lock quick-change attachment for tool-free disc swaps\u003c\/li\u003e\n  \u003cli\u003e20,000 RPM maximum speed rating for high-speed handheld disc sanders\u003c\/li\u003e\n  \u003cli\u003eCompatible with 300 series stainless, brass, bronze, hard and soft carbon steels, and titanium\u003c\/li\u003e\n  \u003cli\u003eBrown coated face resists loading on soft and hard metals alike\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 Type S Power-Lock quick-change spindle.

Before mounting, inspect the backing pad for damage and confirm the spindle speed rating meets or exceeds 20,000 RPM. Always power down and disconnect the sander from its power source before changing discs. Wear appropriate eye protection and follow ANSI B7.1 guidelines for abrasive disc use.\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: 180\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Very Fine\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: X-weight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlexibility\u003c\/strong\u003e: Rigid\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Brown\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttaching System\u003c\/strong\u003e: Type S Power-Lock\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 20,000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMachine Compatibility\u003c\/strong\u003e: Handheld Disc Sander\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: 300 Series Stainless, Brass, Bronze, Hard Carbon Steels, Soft Carbon Steels, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R766\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 disc\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\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: 69957399658\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT","offers":[{"title":"Default Title","offer_id":51560485257522,"sku":"69957399658","price":6271.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cdd5058703278286dc6bb86afaaae680.jpg?v=1786452929","url":"https:\/\/voomisupply.com\/products\/merit-abrasives-69957399658-quick-change-disc-180-grit-3in","provider":"Voomi Supply","version":"1.0","type":"link"}
