Machined from steel and hardened to 60 to 65 HRC, this bushing resists wear through repeated drilling cycles. It installs without a lock ring or retainer — the press fit holds the bushing permanently in the jig plate. The headed design provides a positive shoulder stop against the plate surface, ensuring consistent seating depth. Inside diameter is 0.0625 inches with a tolerance of +0.0001 to +0.0004 inches, maintaining tight guidance for small-diameter drill bits used in precision metalworking and machining operations.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for use in drill jigs, fixtures, and tooling plates where a permanent, non-renewable bushing is required. The 5\/32 inch body outside diameter and 1\/4 inch head outside diameter make it appropriate for close-tolerance jig plate bores in light to medium production environments. Machinists, tool-and-die makers, and fixture builders typically specify this part when a fixed guide bushing is needed for small-diameter hole drilling. It is supplied as an individual unit and is not intended for applications requiring bushing renewal or liner-style installation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePress fit installation — no retaining ring or lock required\u003c\/li\u003e\n\u003cli\u003eHeaded (Type H) design provides positive shoulder stop against jig plate surface\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 +0.0001 to +0.0004 inches for precise drill guidance\u003c\/li\u003e\n\u003cli\u003eNon-renewable fixed bushing per ANSI standards\u003c\/li\u003e\n\u003cli\u003eHead outside diameter of 1\/4 inch, head height of 3\/32 inch\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a permanent press fit replacement or new-installation headed drill bushing for drill jigs and fixtures requiring a Type H bushing with a 0.0625 inch inside diameter and 5\/32 inch body outside diameter, conforming to ANSI bushing standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePress fit bushings are installed by a qualified machinist or toolmaker using an arbor press or hydraulic press — do not drive with a hammer, as this can damage the bore tolerance or distort the bushing. The receiving hole in the jig plate must be precision-bored to the correct interference fit per ANSI specifications before installation. Once pressed in, this bushing is not intended to be removed or replaced. Confirm jig plate and bushing bore dimensions before pressing to avoid scrapping the plate.\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: 0.0625 inches (1\/16 inch)\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: 0.15625 inches (5\/32 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.09375 inches (3\/32 inch)\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\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\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: H104BR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51732112376114,"sku":"H104BR","price":37.22,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a3df753bfacdecf7a1650e3bb823de6_3aac93fd-6592-423f-b7fa-3e3dc203f8f7.jpg?v=1788739335","url":"https:\/\/voomisupply.com\/products\/boneham-h104br-press-fit-headed-drill-bushing-type-h","provider":"Voomi Supply","version":"1.0","type":"link"}
