Constructed from steel, this bushing features an inside diameter of 0.086 inches (wire gauge #44) and a body outside diameter of 13\/64 inches. The headed design provides a positive stop against the jig plate surface, keeping the bushing seated and preventing it from being pulled through during tool withdrawal. Machinists and toolmakers install this bushing permanently into a jig body where the hole location does not change between operations.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for use in production drilling jigs and fixtures where a fixed, non-renewable bushing is required. The press fit installation method means the bushing is driven or pressed directly into the jig liner hole and is not intended for routine replacement. Typical applications include small-diameter precision drilling, reaming guide, and similar close-tolerance tooling setups in both job shop and production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType H headed design provides a positive axial stop against the jig plate face\u003c\/li\u003e\n  \u003cli\u003ePress fit installation method — no set screw or lock required\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of +0.0001 to +0.0004 inches for precise tool guidance\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in repetitive drilling applications\u003c\/li\u003e\n  \u003cli\u003eNon-renewable (permanent) bushing — suited for fixed hole-location jigs\u003c\/li\u003e\n  \u003cli\u003eWire gauge equivalent #44 inside diameter for compatibility with standard drill sizing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or original-fit press fit headed drill bushing for use in standard drill jig fixtures requiring a Type H bushing with a 0.086 inch inside diameter and 13\/64 inch body outside diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by toolmakers or machinists using an arbor press or similar pressing equipment — never drive the bushing with a hammer directly on the head or bore face. Ensure the receiving hole in the jig plate is clean, deburred, and held to the proper interference fit tolerance before pressing. Once installed, this bushing is not designed for removal or field replacement without potential damage to the jig body. Always verify tool clearance and bushing seating depth before beginning production runs.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Type\u003c\/strong\u003e: Type H (Headed, Press Fit)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.086 inches (Wire Gauge #44)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: +0.0001 to +0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 13\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 19\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 3\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Press Fit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRenewable\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCounterbored\u003c\/strong\u003e: No\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: H135CN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51738111803698,"sku":"H135CN","price":24.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b617461c6c05368cdcf2b33f32fca5ff_daadb17a-feae-491b-a8a5-d5cfc8a84ac0.jpg?v=1788796268","url":"https:\/\/voomisupply.com\/products\/boneham-h135cn-press-fit-headed-drill-bushing-type-h","provider":"Voomi Supply","version":"1.0","type":"link"}
