The mandrel features a 0.125-inch pilot diameter and 0.5-inch pilot length, paired with a 0.25-inch shank diameter and 1-inch shank length, for a 2.25-inch overall length. The quick-change design allows for fast cartridge roll swaps without additional tooling. It is used by machinists, fabricators, and maintenance technicians for deburring, blending, and finishing in tight or contoured areas.\u003c\/p\u003e\u003cp\u003eThis mandrel is suited for light metalworking, automotive, and general fabrication applications where abrasive cartridge rolls are required. The quick-change feature makes it practical in production environments where multiple grit sizes are cycled through during a single job. It is commonly used in hand-held die grinder setups for interior bore work, slot finishing, and weld blending.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.125-inch pilot diameter accepts standard cartridge rolls\u003c\/li\u003e\n\u003cli\u003e0.5-inch pilot length provides secure roll retention\u003c\/li\u003e\n\u003cli\u003e0.25-inch shank diameter fits common die grinder collets\u003c\/li\u003e\n\u003cli\u003e2.25-inch overall length for reach in confined areas\u003c\/li\u003e\n\u003cli\u003eQuick-change design speeds up cartridge roll replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement mandrel compatible with standard abrasive cartridge rolls sized to fit a 0.125-inch pilot diameter, for use in die grinders with a 0.25-inch collet.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists or fabricators using a standard die grinder collet wrench. Ensure the die grinder is fully powered off and disconnected from the air supply or power source before changing mandrels or cartridge rolls. Do not exceed the RPM rating of the abrasive cartridge roll being used. Inspect the mandrel pilot for wear before each use and replace if deformation is visible.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePilot Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePilot Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChange Type\u003c\/strong\u003e: Quick Change\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.33 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: CR-7\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51689144910130,"sku":"CR-7","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0a3cc093b7b0b7a065e37938f1224c1c.jpg?v=1788255218","url":"https:\/\/voomisupply.com\/products\/value-collection-cr-7-cartridge-roll-mandrel-quick-change","provider":"Voomi Supply","version":"1.0","type":"link"}
