Each mandrel expands radially to grip the interior bore of a part, providing concentric, secure clamping without marring the outside surface. The set covers a grip range of 0.5 inches to 2 inches face diameter, making it suitable for a broad range of workpiece sizes in one kit. Machinists and toolroom technicians reach for expanding mandrels when a standard arbor cannot hold the part or when outside surfaces must remain undamaged. The set ships as a complete unit weighing 16 pounds.\u003c\/p\u003e\n\u003cp\u003eThis mandrel set is used in metal-turning applications across job shops, production machining facilities, and maintenance repair operations. The 0.5 to 2 inch grip range covers a wide variety of cylindrical and ring-type workpieces typical in general machining, gear finishing, and bushing work. It is appropriate for both manual engine lathes and CNC turning applications where workholding flexibility is required across multiple bore sizes without changing fixtures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e8-piece set covers grip range from 0.5 inches to 2 inches face diameter\u003c\/li\u003e\n  \u003cli\u003eExpanding design grips interior bores for concentric, damage-free workholding\u003c\/li\u003e\n  \u003cli\u003eSingle kit replaces multiple fixed-size mandrels for versatile shop use\u003c\/li\u003e\n  \u003cli\u003eMaximum face diameter of 2 inches suits common ring, gear, and bushing workpieces\u003c\/li\u003e\n  \u003cli\u003eSold as a complete set — no additional mandrels required across the covered range\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a general-purpose expanding mandrel set suitable for use on standard engine lathes and CNC turning centers that accept center-mount workholding with bore diameters from 0.5 inches to 2 inches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eExpanding mandrels are typically installed and removed by a qualified machinist or toolroom technician. Always ensure the lathe spindle is fully stopped and the machine is powered down before mounting or removing any mandrel. Verify that the selected mandrel size matches the workpiece bore within the specified grip range before applying clamping force. Overtightening the expansion mechanism beyond rated grip capacity can damage both the mandrel and the workpiece — follow the manufacturer's torque and expansion guidance included with the set.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Face Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Face Diameter\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Grip\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Mandrels\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 16 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23153000\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: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 262-3030\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51691858362674,"sku":"262-3030","price":426.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/80f660798acc9dd9a7266db728e6558e.jpg?v=1788290532","url":"https:\/\/voomisupply.com\/products\/value-collection-262-3030-expanding-lathe-mandrel-set","provider":"Voomi Supply","version":"1.0","type":"link"}
