This liner has a 7\/16 inch inside diameter and a 5\/8 inch body outside diameter, with a 1\/2 inch liner length. Constructed from alloy steel and hardened to 60-65 HRC, it delivers the wear resistance required in high-cycle drilling operations. Installation is accomplished via press fit into the jig plate, securing the liner without the need for external fasteners or retaining hardware. Tool and die makers, machinists, and fixture builders install this type of component in production drilling setups.\u003c\/p\u003e\u003cp\u003eThe LT408XKQ is suited for use in drill jigs and machining fixtures in industrial, job shop, and manufacturing environments. It serves as the stationary liner that receives a renewable slip or fixed drill bushing, allowing worn bushings to be replaced without disturbing the jig plate itself. This liner type is commonly used where tool replacement frequency is high and maintaining positional accuracy is critical across production runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/16 inch inside diameter for precise bushing location\u003c\/li\u003e\n\u003cli\u003e5\/8 inch body outside diameter for secure press fit seating in jig plate\u003c\/li\u003e\n\u003cli\u003e1\/2 inch liner length provides stable engagement depth\u003c\/li\u003e\n\u003cli\u003eAlloy steel construction hardened to 60-65 HRC for long service life\u003c\/li\u003e\n\u003cli\u003eHeadless L-type design allows flush or below-surface installation\u003c\/li\u003e\n\u003cli\u003ePress fit installation method eliminates need for additional fasteners\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation liner for standard L-type drill jig and fixture assemblies requiring a 7\/16 inch inside diameter headless liner with press fit installation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePress fit installation requires a hydraulic or arbor press; do not drive with a hammer, as impact can crack hardened steel components or distort the jig plate bore. Ensure the receiving bore in the jig plate is clean, within tolerance, and free of burrs before pressing. Machinist or tool and die trade personnel typically perform this installation. Verify liner seating is flush or to the specified depth before use in production.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLiner Length\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLiner Industry Code\u003c\/strong\u003e: L\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Press Fit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Alloy Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 60-65 HRC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31171603\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BONEHAM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: LT408XKQ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51733929460018,"sku":"LT408XKQ","price":15.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772b15bcdae08b51210f0eebedf78b00_e3df54c0-f285-4a6e-8aa0-c97fc20beabf.jpg?v=1788759990","url":"https:\/\/voomisupply.com\/products\/boneham-lt408xkq-drill-bushing-liner-7-16-inch-id","provider":"Voomi Supply","version":"1.0","type":"link"}
