It accepts a standard 1\/4-inch shank, making it compatible with common die grinders and rotary tools used in metal fabrication, weld blending, and surface prep work. Rated to a maximum of 25,000 RPM, this backing pad handles high-speed operation without compromising disc retention. The medium density construction provides a balance of conformability and support across flat and moderately contoured surfaces. It is the type of component installed and replaced by metalworking tradespeople, fabricators, and maintenance technicians who rely on consistent disc backing for controlled material removal.\u003c\/p\u003e\n\u003cp\u003eThis backing pad is suited for use in industrial, manufacturing, and maintenance environments where quick-change abrasive disc systems are standard. The Type R quick-change interface allows for fast disc swaps without additional hardware, reducing downtime during surface preparation, deburring, blending, and finishing operations. It is commonly used with angle grinders and die grinders in both shop and field settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eQuick-Change Type R interface for tool-free disc changes\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch shank diameter fits standard die grinders and rotary tools\u003c\/li\u003e\n  \u003cli\u003e25,000 RPM maximum speed rating for high-speed applications\u003c\/li\u003e\n  \u003cli\u003eMedium density construction balances surface conformability and disc support\u003c\/li\u003e\n  \u003cli\u003eCompact and lightweight at 0.07 pounds for reduced operator fatigue\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement backing pad for use with Quick-Change Type R abrasive disc systems on standard 1\/4-inch shank die grinders and rotary tools.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by metalworking technicians or maintenance trades using standard die grinders. Before mounting or removing the backing pad, ensure the tool is fully powered down and disconnected from the air supply or power source. Thread the 1\/4-inch shank securely into the tool collet according to the tool manufacturer torque guidance. Always confirm the assembled disc and pad combination does not exceed the 25,000 RPM maximum speed rating before operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Pad Type\u003c\/strong\u003e: Quick-Change Type R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Speed\u003c\/strong\u003e: 25,000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDensity\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: STANDARD ABRASIVES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7100049328\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51542432383282,"sku":"7100049328","price":112.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a8145c3a0de87e33cfae669168733712.jpg?v=1785900291","url":"https:\/\/voomisupply.com\/products\/standard-abrasives-7100049328-disc-backing-pad-type-r","provider":"Voomi Supply","version":"1.0","type":"link"}
