It features an inside diameter of 5\/64 inches, a body outside diameter of 13\/64 inches, and a length under head of 5\/16 inches. Constructed from steel hardened to 60 to 65 HRC, the bushing resists wear through repeated tool passes. The headed design seats against the jig plate surface, providing positive axial location without additional fasteners. It is a non-renewable, permanently installed component pressed directly into the jig body. Machinists, tool and die makers, and manufacturing engineers specify this bushing where a fixed, tight-tolerance guide is required.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for production and prototype jig plates in light to medium machining applications. The press fit installation method makes it appropriate for applications where the bushing will not be swapped between operations. It is commonly used in drill jig assemblies across general manufacturing, metalworking, and precision fabrication environments. The inside diameter tolerance of plus 0.0001 to plus 0.0004 inches supports accurate hole location and consistent tool guidance across production runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType H headed design provides positive axial seating against the jig plate face\u003c\/li\u003e\n\u003cli\u003ePress fit installation secures the bushing permanently without fasteners\u003c\/li\u003e\n\u003cli\u003eSteel construction hardened to 60 to 65 HRC for extended wear life\u003c\/li\u003e\n\u003cli\u003eInside diameter tolerance of plus 0.0001 to plus 0.0004 inches for precise tool guidance\u003c\/li\u003e\n\u003cli\u003eNon-renewable configuration suited for fixed, single-operation jig setups\u003c\/li\u003e\n\u003cli\u003eMeets ANSI standards for drill bushing dimensions and tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style press fit headed drill bushing for use in standard drill jig plates and fixtures requiring a Type H, permanently installed bushing per ANSI specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by pressing the bushing into a properly sized and finished jig plate bore using an arbor press or hydraulic press. The bore in the jig plate must be machined to the correct interference fit tolerance before pressing to avoid cracking the bushing or distorting the ID. No heat, adhesive, or fasteners are required for a standard press fit installation. Because this is a non-renewable bushing, replacement requires machining out the existing bushing and refurbishing the bore.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Type\u003c\/strong\u003e: Type H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Press Fit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 5\/64 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: 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\u003eHead or Headless\u003c\/strong\u003e: Head\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 60 to 65 HRC\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\u003eStandards\u003c\/strong\u003e: ANSI\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: H135CF\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51753042379058,"sku":"H135CF","price":24.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a3df753bfacdecf7a1650e3bb823de6_b25e7d27-065a-4190-a69e-cb9344f1d578.jpg?v=1788932363","url":"https:\/\/voomisupply.com\/products\/boneham-h135cf-press-fit-headed-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
