It is designed to guide cutting tools accurately during drilling, reaming, and boring operations in jig and fixture applications. The bushing features an inside diameter of 0.386 inches with a tight tolerance of +0.0001 to +0.0005 inches, ensuring precise hole location and consistent tool guidance. The headed design seats against the jig plate surface to control depth positioning without requiring a locking collar. This part is installed by toolmakers, machinists, and fixture builders working in production and prototype environments.\u003c\/p\u003e\n\u003cp\u003eThe H484JW is suited for press fit installation into drill jig plates and fixtures where a permanent, non-renewable bushing is required. Its 3\/4-inch body outside diameter and 1\/4-inch length under head make it appropriate for moderate-thickness jig plates. The steel construction provides durability for repetitive drilling cycles in both light and medium production runs. No counterbore is required for installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType H headed design seats flush against jig plate surface for controlled depth positioning\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of +0.0001 to +0.0005 inches for accurate tool guidance\u003c\/li\u003e\n  \u003cli\u003ePress fit installation — no locking collar or renewal required\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides wear resistance across repeated drilling cycles\u003c\/li\u003e\n  \u003cli\u003eHead outside diameter of 59\/64 inches and head height of 7\/32 inches for positive seating\u003c\/li\u003e\n  \u003cli\u003eNon-renewable design suited for permanent fixture applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard press fit headed drill bushing for use in drill jigs and machining fixtures requiring a permanent bushing with a 0.386-inch bore and 3\/4-inch body outside diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by toolmakers or machinists using a press or arbor press to seat the bushing into the jig plate bore. Ensure the receiving bore in the jig plate is dimensioned to the correct interference fit before pressing. The jig plate and workpiece should be secured and all cutting operations should be performed with appropriate guarding in place. Do not use impact tools to drive the bushing, as this may damage the head seating surface or alter bore alignment.\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 (Letter)\u003c\/strong\u003e: W\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Decimal)\u003c\/strong\u003e: 0.386 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: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 59\/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\u003eMaterial\u003c\/strong\u003e: Steel\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\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: H484JW\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51736719196466,"sku":"H484JW","price":25.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b617461c6c05368cdcf2b33f32fca5ff_3aaffa71-969f-46f8-b42a-1b77de788f1a.jpg?v=1788779518","url":"https:\/\/voomisupply.com\/products\/boneham-h484jw-press-fit-headed-drill-bushing-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
