At 1.5 inches in diameter and rated to 30,000 RPM, this disc carries an 80-grit medium-grade zirconia alumina abrasive bonded to a heavy Y-weight polyester backing. The flexible polyester cloth construction handles aggressive stock removal without loading or glazing. A self-lubricating treatment reduces heat buildup during extended grinding runs, extending disc life and improving cut consistency on hard and abrasive workpiece materials.\u003c\/p\u003e\u003cp\u003eThis disc is suited for metal fabrication, weld blending, deburring, and surface prep work across a wide range of materials. Rated applications include 300 and 400 series stainless steel, aluminum, brass, bronze, hard and soft carbon steels, fiberglass and composite materials, and hard and soft woods. The quick-change Type R mounting system allows fast disc swaps without tools, making it practical for production environments and fieldwork. It is used by metal fabricators, pipefitters, welders, and general maintenance trades operating handheld disc sanders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e80-grit zirconia alumina abrasive for aggressive stock removal and weld blending\u003c\/li\u003e\n\u003cli\u003eHeavy Y-weight polyester backing provides durability under high-pressure grinding\u003c\/li\u003e\n\u003cli\u003eSelf-lubricating treatment reduces heat and extends disc life\u003c\/li\u003e\n\u003cli\u003ePower-Lock Type R quick-change attachment for tool-free disc changes\u003c\/li\u003e\n\u003cli\u003eRated to 30,000 RPM for use with high-speed handheld disc sanders\u003c\/li\u003e\n\u003cli\u003eFlexible construction conforms to contoured and irregular surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with handheld disc sanders equipped with a Power-Lock Type R quick-change attaching system.

Verify the spindle speed of the tool does not exceed the 30,000 RPM maximum rating marked on the disc before use. Inspect the disc for damage before mounting and discard any disc that shows cracks, tears, or delamination. Eye protection and appropriate PPE should be worn during all grinding operations per ANSI and applicable shop safety standards.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Zirconia Alumina\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: Flexible\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 30,000\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\u003eDisc Color\u003c\/strong\u003e: Blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: R801\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: 0.008 pounds\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: OLD08834167104\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT","offers":[{"title":"Default Title","offer_id":51560206860594,"sku":"OLD08834167104","price":17709.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/521c472e16ed7e57fe6787541719d8ce.jpg?v=1786449287","url":"https:\/\/voomisupply.com\/products\/merit-abrasives-old08834167104-quick-change-disc-80-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
