It features a 9\/64 inch inside diameter and a 1\/4 inch body outside diameter, with a length under head of 1-3\/8 inches. The bushing is pressed directly into a drill jig plate without the need for locking mechanisms, making it a permanent guide solution. Hardness runs 60 to 65 HRC, providing long service life under repeated drill, reamer, or punch passes. Inside diameter tolerance is held to +0.0001 to +0.0004 inches for consistent hole location accuracy. Machinists and toolmakers install this bushing in production and prototype jig plates.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for metalworking, machining, and fabrication environments where repeatable hole positioning is critical. The headed design seats flush against the jig plate surface and the counterbored head recess accepts the flange, keeping the bushing secure during high-cycle drilling operations. It is a fixed, non-renewable bushing intended for permanent installation in jig tooling used across light to medium production runs in machine shops and manufacturing facilities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType H press fit installation — no locking collar or liner required\u003c\/li\u003e\n  \u003cli\u003eHardness of 60 to 65 HRC for extended wear resistance under repeated tooling passes\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of +0.0001 to +0.0004 inches for precise hole guidance\u003c\/li\u003e\n  \u003cli\u003eCounterbored head design for flush, stable seating in jig plates\u003c\/li\u003e\n  \u003cli\u003eNon-renewable fixed bushing — designed for permanent jig installation\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards for drill bushing dimensions and tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style fixed drill bushing for use in standard drill jig plates requiring a Type H press fit headed bushing with a 9\/64 inch bore.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by toolmakers or machinists using an arbor press or hydraulic press to drive the bushing into the prepared jig plate bore. The jig plate bore must be machined to the correct interference fit tolerance before pressing to avoid cracking or misalignment. Do not hammer the bushing directly without a driver tool, as this can damage the head or distort the bore. Once pressed in, this bushing is not designed for removal and replacement.\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 Press Fit Headed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 9\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 23\/64 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\u003eInside Diameter Tolerance\u003c\/strong\u003e: +0.0001 to +0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 60 to 65 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCounterbored\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRenewable\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Press Fit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\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: H1622EG\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51734259106098,"sku":"H1622EG","price":65.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a3df753bfacdecf7a1650e3bb823de6_9aac3a8d-f478-44e3-a809-7e0565b11084.jpg?v=1788761599","url":"https:\/\/voomisupply.com\/products\/boneham-h1622eg-press-fit-headed-drill-bushing-type-h","provider":"Voomi Supply","version":"1.0","type":"link"}
