The bushing features a 45\/64 inch inside diameter and a 1 inch body outside diameter, with a 1\/2 inch length under the head. It installs by press fit into a drill jig or fixture plate without the need for a locking mechanism. Machinists and tooling technicians install this bushing as a permanent guide for drill bits, reamers, or similar cutting tools where consistent hole location and alignment are required across repeated operations.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for use in drill jig assemblies in machine shops, manufacturing lines, and fabrication environments. The headed design provides a positive stop against the jig plate surface, ensuring consistent seating depth on every installation. The press fit method locks the bushing in place without fasteners, making it appropriate for high-cycle, production-volume drilling setups where repeatability and positional accuracy are critical. It is a non-renewable bushing, meaning it is intended as a fixed installation rather than a field-replaceable liner.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType H headed design with 1-15\/64 inch head outside diameter and 5\/16 inch head height for positive seating against jig plate\u003c\/li\u003e\n  \u003cli\u003ePress fit installation method secures bushing without fasteners or locking rings\u003c\/li\u003e\n  \u003cli\u003eSteel construction hardened to 60 to 65 HRC for wear resistance in high-cycle drilling\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of plus 0.0001 to plus 0.0005 inch for precise tool guidance\u003c\/li\u003e\n  \u003cli\u003eANSI standard compliant geometry for interchangeability with standard jig tooling\u003c\/li\u003e\n  \u003cli\u003eNon-renewable, fixed-mount design suited for permanent jig setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ANSI-standard Type H press fit headed drill bushing for use in drill jigs and fixture plates requiring a permanent, headed bushing with a 45\/64 inch bore.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of press fit drill bushings is typically performed by toolmakers or machining technicians using an arbor press or hydraulic press to drive the bushing flush into a prepared jig plate bore. The receiving hole must be machined to the correct press fit tolerance before installation to avoid damage to the bushing or jig plate. Once pressed in, this bushing is not intended for removal and reinstallation. Always verify bore alignment and cleanliness before pressing the bushing into position.\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\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: 45\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: plus 0.0001 to plus 0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 1-15\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1\/2 inches\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\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: H648MU\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51738727219506,"sku":"H648MU","price":23.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a3df753bfacdecf7a1650e3bb823de6_07aef3cb-149c-4cd1-8228-fcf72ab02a0c.jpg?v=1788803508","url":"https:\/\/voomisupply.com\/products\/boneham-h648mu-press-fit-headed-drill-bushing-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
