This liner features a 3\/8 inch inside diameter and a 5\/8 inch body outside diameter, with a 5\/8 inch liner length. Constructed from alloy steel and heat treated to a hardness of 60-65 HRC, it delivers consistent hole location accuracy and resists wear under repeated drilling cycles. Installation is accomplished via press fit, seating the liner permanently into a jig plate or master bushing without the need for a locking mechanism.\u003c\/p\u003e\n\u003cp\u003eThe LT4010JQ is used in production and toolroom environments where drill jigs require a fixed, headless liner that sits flush with or below the jig plate surface. The headless design is preferred when tool clearance above the plate is limited or when a clean, unobstructed work surface is required. Machinists, tool and die makers, and precision metalworking shops routinely use this style of liner in multi-station drill fixtures and transfer jigs where repeatable hole location is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8 inch inside diameter provides a close-tolerance guide bore for compatible drill sizes\u003c\/li\u003e\n  \u003cli\u003e5\/8 inch body outside diameter for press fit installation into the jig plate or master bushing\u003c\/li\u003e\n  \u003cli\u003e5\/8 inch liner length suited for standard jig plate thicknesses\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction heat treated to 60-65 HRC for extended wear life\u003c\/li\u003e\n  \u003cli\u003eHeadless design sits flush with the plate surface, maximizing tool clearance\u003c\/li\u003e\n  \u003cli\u003ePress fit installation eliminates the need for additional locking hardware\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation liner for standard L-series headless drill bushing applications in drill jig fixtures and tooling plates.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePress fit installation should be performed using an arbor press or hydraulic press to avoid damaging the bore or outer diameter of the liner. Ensure the receiving hole in the jig plate or master bushing is machined to the correct interference fit tolerance before pressing. Do not use a hammer to drive the liner directly, as this can distort the inside diameter and compromise hole location accuracy. Follow applicable shop safety procedures and de-burr the installation bore prior to assembly.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 3\/8 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: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLiner Industry Code\u003c\/strong\u003e: L\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\u003eInstallation Method\u003c\/strong\u003e: Press Fit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31171603\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: BONEHAM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: LT4010JQ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51730982469938,"sku":"LT4010JQ","price":19.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772b15bcdae08b51210f0eebedf78b00_8c86addf-c9d6-4c03-91ea-eb1e5764c3a3.jpg?v=1788725535","url":"https:\/\/voomisupply.com\/products\/boneham-lt4010jq-headless-l-drill-bushing-liner-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
