Built from steel, this bushing features an inside diameter of 0.386 inches (Letter W) and a body outside diameter of 0.75 inches, with an overall length of 0.75 inches. The headless design allows the bushing to sit flush with the jig plate surface, making it suitable for applications where a protruding head would interfere with the workpiece or tooling setup. The inside diameter tolerance of +0.0001 to +0.0005 inches ensures consistent drill guidance and repeatable hole placement across production runs.\u003c\/p\u003e\n\u003cp\u003eThis bushing is used in metalworking, machining, and fabrication environments where a permanent, non-renewable drill guide is required. Press fit installation makes it ideal for fixed jig plates where the bushing will not need to be replaced during the service life of the fixture. Machinists and toolmakers install this type of bushing in drill jigs, assembly fixtures, and transfer tooling to maintain accurate hole location tolerances across multiple workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation method for permanent, fixed mounting in jig plates\u003c\/li\u003e\n  \u003cli\u003eHeadless design sits flush with the jig surface, no protrusion above the plate\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 0.386 inches (Letter W) with +0.0001 to +0.0005 inches tolerance for precise drill guidance\u003c\/li\u003e\n  \u003cli\u003eBody outside diameter of 0.75 inches and overall length of 0.75 inches\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in production drilling applications\u003c\/li\u003e\n  \u003cli\u003eNon-renewable bushing — intended as a permanent fixture component\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct fitment for standard P-series press fit headless drill bushing applications conforming to Bushing Industry Code P specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePress fit bushings are installed by machinists or toolmakers using an arbor press or hydraulic press to drive the bushing into a precision-bored hole in the jig plate. The receiving bore must be machined to the correct tolerance to achieve a proper interference fit — consult the bushing manufacturer specifications for recommended bore dimensions. Because this is a non-renewable bushing, removal typically damages the bushing and may affect the jig plate bore. Ensure the bushing is fully seated and flush before use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: P\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 (Decimal)\u003c\/strong\u003e: 0.3860 inches\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 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\u003eOverall Bushing Length\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Headless\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: P4812JW\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51746172764466,"sku":"P4812JW","price":17.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/79c55b9503f5b2b51a95049f224e918b_aac3db02-7528-409f-86dd-7ed039b29ac6.jpg?v=1788866714","url":"https:\/\/voomisupply.com\/products\/boneham-p4812jw-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
