With an inside diameter of 25\/64 inches and a body outside diameter of 5\/8 inches, this bushing provides consistent hole location and bore guidance across repeated drilling operations. The head outside diameter measures 51\/64 inches with a head height of 7\/32 inches, and the length under head is 1\/2 inches. It is installed by press fit and is not designed to be renewed or replaced after installation. Machinists, tool-and-die makers, and production drilling operations rely on this type of bushing to maintain tight positional tolerances at the drill point.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for use in drill jigs and machining fixtures in industrial, manufacturing, and production environments. The Type H headed design seats against the jig plate surface, preventing the bushing from being pushed through during drilling. It is appropriate for applications requiring permanent bushing installation where chip clearance and drill guidance accuracy are critical. Inside diameter tolerance is held to +0.0001 to +0.0005 inches, supporting close-tolerance drilling work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation for permanent, fixed positioning in the jig plate\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of +0.0001 to +0.0005 inches for precise drill guidance\u003c\/li\u003e\n  \u003cli\u003eHeaded (Type H) design seats flush against jig plate surface to resist push-through\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in repetitive production drilling cycles\u003c\/li\u003e\n  \u003cli\u003eHead outside diameter of 51\/64 inches and head height of 7\/32 inches for positive seating\u003c\/li\u003e\n  \u003cli\u003eNot counterbored and not renewable — intended for permanent fixture use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Type H press fit headed drill bushing for use in drill jigs and machining fixtures requiring a 25\/64-inch bore with a 5\/8-inch body outside diameter press fit installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or tool-and-die professionals using a press to drive the bushing into a properly sized jig plate bore. The receiving hole in the jig plate must be machined to the appropriate interference fit tolerance to ensure the bushing seats securely. Because this is a permanent press fit bushing, it is not intended for removal or reuse once installed. Inspect the jig plate bore for burrs or debris before pressing the bushing into place to avoid damage to the bushing or the plate.\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 (Headed)\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: 25\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: +0.0001 to +0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 51\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 7\/32 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\u003eCounterbored\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRenewable\u003c\/strong\u003e: No\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: H408JY\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51728651288882,"sku":"H408JY","price":18.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1c979c4da34daec4ad20c4c3b91ce9b5.jpg?v=1788694435","url":"https:\/\/voomisupply.com\/products\/boneham-h408jy-press-fit-headed-drill-bushing-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
