The mandrel expands to grip bores ranging from 1-1\/2 inches to 2 inches, providing a secure, centered hold without requiring external clamping. The 1-1\/2-inch shank diameter fits standard lathe spindle bores and tool holders, while the 5-inch sleeve length and 11-1\/2-inch arbor length accommodate a range of workpiece depths. Machinists and toolroom technicians use this type of mandrel when concentricity between the bore and the outer diameter is critical.\u003c\/p\u003e\n\u003cp\u003eThis expanding lathe mandrel is suited for production and toolroom environments where inside-diameter workholding is required. Typical applications include turning the OD of bushings, sleeves, rings, and other cylindrical parts that must run true to a bored center. The 1-1\/2- to 2-inch grip range covers a common bore size class found in medium-scale machined components. It is intended for use on manual engine lathes and compatible CNC turning centers that accept the corresponding shank diameter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eExpanding grip range of 1-1\/2 inches to 2 inches suits a wide variety of bored workpieces\u003c\/li\u003e\n  \u003cli\u003e1-1\/2-inch shank diameter for secure mounting in standard lathe spindle or tool holder\u003c\/li\u003e\n  \u003cli\u003e5-inch sleeve length provides stable workpiece support along the bore\u003c\/li\u003e\n  \u003cli\u003e11-1\/2-inch overall arbor length accommodates deeper or longer workpieces\u003c\/li\u003e\n  \u003cli\u003eInside-diameter workholding maintains concentricity between bore and OD during turning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style expanding mandrel for use on manual engine lathes and turning centers that accept a 1-1\/2-inch shank, with a bore grip range of 1-1\/2 inches to 2 inches.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and use of lathe mandrels should be performed by qualified machinists familiar with lathe workholding practices. Power down and lock out the lathe spindle before mounting or removing the mandrel. Ensure the shank is clean and fully seated in the spindle or holder before engaging the workpiece. Do not exceed the mandrel grip range, as over-expansion can damage the sleeve or the workpiece bore.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Grip Diameter\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Grip Diameter\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.406 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSleeve Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Length\u003c\/strong\u003e: 11-1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6.66 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112800\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: 262-3064\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714927001906,"sku":"262-3064","price":97.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/91ab70fff1cd6a2649f1afe50b3f69f6.jpg?v=1788507977","url":"https:\/\/voomisupply.com\/products\/value-collection-262-3064-expanding-lathe-mandrel","provider":"Voomi Supply","version":"1.0","type":"link"}
