It accepts a standard 1\/4-20 male thread shank with a 1\/4-inch shank diameter and is rated to a maximum of 20,000 RPM, making it suitable for high-speed die grinders and right-angle tools. The 3-inch pad diameter provides a compact contact surface appropriate for detail work, weld cleanup, and confined-area grinding. Compatible with Quick-Lok quick-change disc systems, this backing pad is a standard consumable tool component used by metal fabricators, pipefitters, and maintenance trades.\u003c\/p\u003e\u003cp\u003eThis backing pad is used in metal fabrication shops, maintenance and repair operations, and field service environments where quick disc changes are needed without dedicated tooling. The 3-inch diameter is well suited for work in tight spaces, around welds, and on irregular surfaces. Its hard-density construction supports aggressive material removal when paired with coarse-grit quick-change discs. The 1\/4-20 male thread interface allows direct mounting to compatible die grinder spindles and right-angle grinder accessories commonly found in industrial and mechanical trade settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-inch pad diameter for compact surface contact and detail work\u003c\/li\u003e\n\u003cli\u003eRated to 20,000 RPM for use with high-speed die grinders\u003c\/li\u003e\n\u003cli\u003e1\/4-20 male thread for direct spindle mounting\u003c\/li\u003e\n\u003cli\u003e1\/4-inch shank diameter fits standard die grinder collets\u003c\/li\u003e\n\u003cli\u003eHard-density construction supports aggressive material removal\u003c\/li\u003e\n\u003cli\u003eQuick-Lok compatibility enables fast disc swaps without tools\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with Quick-Lok quick-change Type S abrasive discs.

Always disconnect the grinder from power or compressed air before mounting or removing the backing pad.

Inspect the pad for wear, cracking, or delamination before each use and replace if damage is found.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePad Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Pad Type\u003c\/strong\u003e: Quick-Change Type S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Male\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 20,000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDensity\u003c\/strong\u003e: Hard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuick-Change Compatibility\u003c\/strong\u003e: Quick-Lok\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.38 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31191506\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: TRU-MAXX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TRU-RS303H\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TRU-MAXX","offers":[{"title":"Default Title","offer_id":51746346533170,"sku":"TRU-RS303H","price":16.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a08167d62c7e09d4cf1ab505bbfda1b.jpg?v=1788868711","url":"https:\/\/voomisupply.com\/products\/tru-maxx-tru-rs303h-disc-backing-pad-quick-change-type-s-3-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
