It is designed to guide drill bits with precision during machining and drilling operations, providing a hardened, accurate bore for repeatable hole placement. The bushing features an inside diameter of 0.228 inches, a body outside diameter of 0.5 inches, and a length under head of 0.75 inches. The head outside diameter measures 0.609 inches (39\/64 inches) with a head height of 0.219 inches (7\/32 inches). This is a permanent, non-renewable bushing installed by press fit into a jig plate or fixture body and is typically handled by machinists, tool and die makers, or precision fabricators.\u003c\/p\u003e\n\u003cp\u003eThe H3212GT is suited for use in drill jigs and fixture plates in manufacturing, maintenance, and production environments. Its headed design seats flush against the jig plate surface, preventing the bushing from being pushed through under drilling load. The steel construction provides durability for repeated drilling cycles. The inside diameter corresponds to wire gauge size Number 1, making it appropriate for guiding drill bits at that nominal diameter in both prototype and production drilling setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation method for permanent, secure seating in jig plate bores\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 0.228 inches with a tight tolerance of plus 0.0001 to plus 0.0004 inches for precise drill guidance\u003c\/li\u003e\n  \u003cli\u003eBody outside diameter of 0.5 inches and length under head of 0.75 inches\u003c\/li\u003e\n  \u003cli\u003eHead outside diameter of 0.609 inches and head height of 0.219 inches to resist axial push-through\u003c\/li\u003e\n  \u003cli\u003eSteel construction for wear resistance and durability in repetitive drilling applications\u003c\/li\u003e\n  \u003cli\u003eNon-renewable (fixed) design; intended for permanent installation in the fixture\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation drill bushing for standard Type H headed press fit applications in drill jigs and machining fixtures requiring a 0.228-inch bore and 0.5-inch body outside diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePress fit bushings are installed by machinists or toolmakers using an arbor press or hydraulic press; hand force alone is not sufficient for proper seating. The receiving bore in the jig plate must be machined to the appropriate interference fit tolerance for the bushing outside diameter before installation. Ensure the jig plate and bushing bore are free of chips and debris prior to pressing. Once installed, this non-renewable bushing is not designed for field removal and replacement without reworking the fixture bore.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.228 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: plus 0.0001 to plus 0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 0.609 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.219 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Type\u003c\/strong\u003e: Type H (Headed)\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: Steel\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  \u003cli\u003e\n\u003cstrong\u003eWire Gauge Size\u003c\/strong\u003e: Number 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: H3212GT\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51748401807666,"sku":"H3212GT","price":20.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b617461c6c05368cdcf2b33f32fca5ff_40f125f3-16b6-4c19-bd5e-5958303f3926.jpg?v=1788893326","url":"https:\/\/voomisupply.com\/products\/boneham-h3212gt-press-fit-headed-drill-bushing-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
