The slotted rubber drum expands outward with centrifugal force as rotational speed increases, keeping the abrasive band tight and seated against the workpiece during operation. The wheel accepts a 1 inch diameter by 1 inch wide abrasive band and is fitted with a 1\/4 inch diameter shank, making it compatible with standard 1\/4 inch collet chucks and drill chucks. It is suited for deburring, blending, and surface conditioning work performed by machinists, fabricators, and maintenance technicians.\u003c\/p\u003e\n\u003cp\u003eThis expander wheel is used in rotary tool setups where consistent band tension is required throughout the grinding pass. Typical applications include metal deburring, weld blending, internal bore finishing, and contour grinding on ferrous and non-ferrous materials. The self-tightening drum design reduces band slippage without manual adjustment, making it practical for production or field maintenance environments where setup time matters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSlotted rubber drum expands with centrifugal force to maintain consistent band tension during use\u003c\/li\u003e\n  \u003cli\u003eAccepts 1 inch diameter by 1 inch wide abrasive bands or belts\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch diameter shank fits standard 1\/4 inch collet chucks and drill chucks\u003c\/li\u003e\n  \u003cli\u003eEliminates need for manual band tensioning adjustments mid-operation\u003c\/li\u003e\n  \u003cli\u003eSuited for deburring, weld blending, and surface finishing on metal workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1 inch diameter by 1 inch wide abrasive bands or belts.

Ensure the tool is powered off and unplugged before mounting or removing the expander wheel from the chuck. Seat the shank fully into the collet or drill chuck and tighten securely before applying the abrasive band. Always confirm the abrasive band rating is appropriate for the operating RPM of the tool being used.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Width\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Band Size\u003c\/strong\u003e: 1 inch diameter x 1 inch wide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChuck Compatibility\u003c\/strong\u003e: 1\/4 inch collet chuck or drill chuck\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: 50051144777179\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: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7000120410\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346811846962,"sku":"7000120410","price":98.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310534597.jpg?v=1782091203","url":"https:\/\/voomisupply.com\/products\/3m-7000120410-rubber-slotted-expander-wheel-1x1-in-1-4-in-shank","provider":"Voomi Supply","version":"1.0","type":"link"}
