It features a 3\/8 inch inside diameter, a 5\/8 inch body outside diameter, and a 1\/2 inch liner length. Constructed from alloy steel hardened to 60-65 HRC, this liner provides the wear resistance needed for repeated drilling operations. Installation is accomplished via press fit, seating the liner securely into a mating jig plate or tooling fixture without the need for a retaining screw. Machinists, tool and die makers, and production maintenance personnel use these liners in drill jigs to maintain hole location accuracy across high-volume part runs.\u003c\/p\u003e\n\u003cp\u003eThis liner is suited for use in drill jigs, fixture plates, and production tooling where a renewable, hardened guide is required. The headless L-type profile is a widely used industry-standard configuration, making it appropriate for setups where the bushing must sit flush or below the surface of the jig plate. Typical applications include metalworking, fabrication, and precision machining environments. The press fit installation method keeps the liner stationary during the drilling cycle without additional hardware.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3\/8 inch inside diameter for direct drill guidance\u003c\/li\u003e\n  \u003cli\u003e5\/8 inch body outside diameter for press fit into standard jig plate bores\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch liner length provides adequate guide depth for most jig applications\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction hardened to 60-65 HRC for extended wear life\u003c\/li\u003e\n  \u003cli\u003eHeadless L-type profile conforms to industry-standard liner geometry\u003c\/li\u003e\n  \u003cli\u003ePress fit installation requires no retaining screws or clips\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard component for use in drill jig plates and fixtures requiring a headless L-type liner with a 3\/8 inch inside diameter and press fit installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolmakers using a press or arbor press to seat the liner flush into the mating bore of the jig plate. The receiving bore must be machined to the appropriate interference fit tolerance before installation. Do not hammer the liner in place without proper press tooling, as this can damage the liner or distort the bore. Verify bore cleanliness and roundness before pressing the liner into position.\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: 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\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31171603\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: LT408JQ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51746651832626,"sku":"LT408JQ","price":16.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772b15bcdae08b51210f0eebedf78b00_a609d473-a317-49ae-ac0f-d70a3e1a8705.jpg?v=1788872199","url":"https:\/\/voomisupply.com\/products\/boneham-lt408jq-drill-bushing-liner-3-8-in-id-headless-l","provider":"Voomi Supply","version":"1.0","type":"link"}
