With a 5\/16-inch inside diameter and a 1\/2-inch body outside diameter, this liner installs via press fit into a prepared jig plate or fixture body. The overall liner length is 1 inch. Manufactured from alloy steel and hardened to 60-65 HRC, it provides the wear resistance needed for repetitive drilling cycles in production environments. This component is installed by tool and die makers, machinists, and fixture builders working in machine shops and manufacturing facilities.\u003c\/p\u003e\n\u003cp\u003eThe L3216IM liner is used in drill jigs where a renewable slip or fixed bushing must be located with precision. The headless L-style liner sits flush with the jig plate surface, making it appropriate for applications where a protruding flange would interfere with workpiece clearance or chip flow. It is a standard industry-coded L liner, suited for use in both light-production and high-volume drilling setups where consistent hole placement is required across identical workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5\/16-inch inside diameter sized to accept standard drill bushing ODs\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch body outside diameter for press fit into standard jig plate bores\u003c\/li\u003e\n  \u003cli\u003e1-inch overall liner length provides stable support for inserted bushings\u003c\/li\u003e\n  \u003cli\u003eAlloy steel construction hardened to 60-65 HRC for extended service life\u003c\/li\u003e\n  \u003cli\u003eHeadless L-style design sits flush with jig plate surface — no protruding flange\u003c\/li\u003e\n  \u003cli\u003ePress fit installation method for secure, permanent seating in fixture bodies\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 drill jig fixtures requiring a 5\/16-inch ID headless liner with a 1\/2-inch body outside diameter and 1-inch liner length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or tool and die maker using a hydraulic or arbor press to seat the liner into a correctly dimensioned and toleranced bore in the jig plate. The receiving bore must be machined to the appropriate press fit tolerance for the 1\/2-inch body outside diameter before installation. Do not drive the liner with a hammer directly on the bore face, as this can distort the ID or crack the hardened liner. Follow applicable shop standards and fixture design specifications for liner retention and replacement intervals.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Liner Length\u003c\/strong\u003e: 1 inch\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\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: L3216IM\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51730764759346,"sku":"L3216IM","price":19.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772b15bcdae08b51210f0eebedf78b00_e51ecc86-ee46-4fc2-acbd-7abc2391b9be.jpg?v=1788722482","url":"https:\/\/voomisupply.com\/products\/boneham-l3216im-headless-l-drill-bushing-liner-5-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
