Constructed from steel, it features an inside diameter of 0.221 inches with a tight tolerance of +0.0001 to +0.0004 inches, making it suitable for close-tolerance drilling operations. The head design keeps the bushing positively located against the jig plate face. This bushing is a permanent, non-renewable installation intended for high-volume production fixtures where consistent hole placement is critical. Machinists and toolmakers are the primary installers.\u003c\/p\u003e\u003cp\u003eThis drill bushing is used in drill jig plates for production machining environments, both in job shops and manufacturing facilities. It is pressed directly into a prepared hole in the jig body and is not intended for removal or replacement after installation. The headed configuration prevents the bushing from being driven through the jig plate during drilling operations, making it well suited for applications where thrust loads are a concern.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePress fit installation for permanent, fixed positioning in jig plates\u003c\/li\u003e\n\u003cli\u003eInside diameter of 0.221 inches with tolerance of +0.0001 to +0.0004 inches for precise tool guidance\u003c\/li\u003e\n\u003cli\u003eHead outside diameter of 1\/2 inch seats flush against jig plate surface to resist axial thrust\u003c\/li\u003e\n\u003cli\u003eSteel construction provides hardness and wear resistance for repeated drill passes\u003c\/li\u003e\n\u003cli\u003eNon-renewable design suited for permanent fixture builds\u003c\/li\u003e\n\u003cli\u003eLength under head of 3\/8 inches accommodates standard jig plate thicknesses\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit component for Type H press fit headed drill bushing applications in standard drill jig and fixture assemblies.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation requires pressing the bushing into a precisely reamed hole in the jig plate using an arbor press or hydraulic press — never hammer directly on the head flange. The receiving hole in the jig must be sized to the correct press fit tolerance for steel-to-steel interference to ensure the bushing does not rotate or pull out during use. Once pressed in, this bushing is not designed for removal. Always verify inside diameter clearance matches the drill or tool shank before committing to production runs.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Type\u003c\/strong\u003e: Type H Press Fit Headed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.221 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter Wire Size\u003c\/strong\u003e: Number 2\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\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 5\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3\/8 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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: H266GQ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51734675620146,"sku":"H266GQ","price":19.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b617461c6c05368cdcf2b33f32fca5ff_76b5ab39-8ade-498a-838f-332ab124f2ea.jpg?v=1788764748","url":"https:\/\/voomisupply.com\/products\/boneham-h266gq-press-fit-headed-drill-bushing-type-h","provider":"Voomi Supply","version":"1.0","type":"link"}
