It features a 7\/16 inch inside diameter and a 5\/8 inch body outside diameter, with a 3\/8 inch liner length. Constructed from alloy steel hardened to 60-65 HRC, this liner delivers the wear resistance required for repetitive drilling operations. Installation is accomplished via press fit, seating the liner firmly into a master bushing or directly into a jig plate without a head flange to interfere with workpiece clearance. It is intended for use by machinists, toolmakers, and maintenance professionals working with drill jigs.\u003c\/p\u003e\n\u003cp\u003eThe LT406XKQ liner is suited for production drilling setups where consistent hole location is critical. The headless profile allows the bushing to sit flush within the jig plate, making it appropriate for applications where a protruding flange would obstruct the workpiece or fixtures. This part is typically installed into a liner or master bushing assembly and is replaced as a wear component during routine jig maintenance to maintain hole-location accuracy across production runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7\/16 inch inside diameter for precise drill guidance\u003c\/li\u003e\n  \u003cli\u003e5\/8 inch body outside diameter for press fit into standard liner bushings\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch liner length for compact jig plate installations\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 design eliminates flange obstruction at the workpiece surface\u003c\/li\u003e\n  \u003cli\u003ePress fit installation for secure, non-rotating seating in the receiving bore\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 L-type liner bushing assemblies used in drill jig fixtures requiring a 7\/16 inch bore and 5\/8 inch outside diameter press fit seating.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePress fit installation requires an arbor press or hydraulic press to seat the liner without damage to the bore or bushing. Ensure the receiving bore is clean, within tolerance, and free of burrs before pressing the liner into place. Do not use a hammer directly on the bushing face. Follow applicable shop safety procedures and verify jig alignment after installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 3\/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\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: LT406XKQ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51755120525618,"sku":"LT406XKQ","price":15.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772b15bcdae08b51210f0eebedf78b00_6df38a07-e1ba-4abd-b254-de0cdcd5e187.jpg?v=1788951347","url":"https:\/\/voomisupply.com\/products\/boneham-lt406xkq-headless-l-drill-bushing-liner-7-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
