The holder face diameter is intentionally smaller than the disc it supports, making it easier to center the disc on the holder and remove it after use. It accepts a 1\/4-inch shank, making it compatible with standard die grinders and rotary tools commonly used in metalworking, fabrication, and maintenance trades. The 4-inch disc holder is well suited for accessing tight spaces and contoured surfaces where larger backing plates cannot reach.\u003c\/p\u003e\u003cp\u003eThis disc holder is used in grinding, blending, and surface preparation tasks across metal fabrication, automotive bodywork, and general maintenance applications. It is particularly useful in hard-to-reach areas where standard orbital or angle grinder setups are impractical. Tradespeople and fabricators mount PSA abrasive discs directly to the face of the holder for controlled material removal on confined or irregular workpieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFace diameter smaller than disc size for easier disc centering and removal\u003c\/li\u003e\n\u003cli\u003e1\/4-inch shank fits standard die grinders and rotary tools\u003c\/li\u003e\n\u003cli\u003e4-inch holder face supports PSA abrasive discs up to corresponding disc size\u003c\/li\u003e\n\u003cli\u003eProvides firm backing support during grinding in confined or hard-to-reach areas\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.08 pounds for reduced operator fatigue during extended use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with PSA abrasive discs featuring a 1\/4-inch center hole, for mounting on die grinders and rotary tools with a 1\/4-inch collet or chuck.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by trade professionals or experienced operators working with die grinders and rotary tools. Ensure the tool is powered off and disconnected from the air supply or power source before attaching or removing the disc holder. Thread the 1\/4-inch shank securely into the tool collet using appropriate wrenches, and verify the shank is fully seated before operating. Always confirm the abrasive disc is firmly adhered to the holder face before beginning grinding operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Holder Face Size\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051144450695\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7010309161\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344147251506,"sku":"7010309161","price":68.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310534472.jpg?v=1782030281","url":"https:\/\/voomisupply.com\/products\/3m-7010309161-psa-disc-holder-4-in-1-4-in-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
