Built to Industry Code P standards, this bushing features a 21\/64-inch inside diameter and a 3\/4-inch outside diameter, with an overall length of 3\/8 inches. Constructed from steel, it delivers the hardness and wear resistance required for repetitive drilling operations in jig and fixture applications. The press fit installation method locks the bushing firmly into the jig plate without a retaining flange, keeping the top surface flush. Machinists, tool-and-die makers, and fabricators rely on this type of bushing for consistent hole placement across production runs.\u003c\/p\u003e\n\u003cp\u003eThis drill bushing is suited for use in drill jigs and fixture plates in light to medium industrial machining environments. The headless design is preferred when a flush or recessed installation is required in the jig body. The inside diameter tolerance of plus 0.0001 to plus 0.0005 inches ensures the bushing provides close guidance for standard drill bits sized to the 21\/64-inch bore. Typical applications include production drilling in metal fabrication shops, maintenance repair, and custom tooling setups where accurate and repeatable hole location is critical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIndustry Code P headless press fit bushing for flush jig plate installation\u003c\/li\u003e\n  \u003cli\u003e21\/64-inch inside diameter with a tolerance of plus 0.0001 to plus 0.0005 inches for precise drill guidance\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch outside diameter and 3\/8-inch overall length for compact footprint in jig plates\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides hardness and wear resistance for production drilling cycles\u003c\/li\u003e\n  \u003cli\u003eNon-renewable design suited for permanent press fit installations\u003c\/li\u003e\n  \u003cli\u003eNo counterbore  -  straight body profile for straightforward press in installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit component for standard P-series headless drill bushing applications in industrial drill jigs and fixture plates.\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 bushing driver to seat the bushing flush with the jig plate surface. The mating hole in the jig plate must be machined to the correct interference fit tolerance to retain the bushing securely during service. Do not hammer the bushing directly without a driver to avoid distorting the bore or damaging the seating surface. Once pressed in, the P486IU is not designed for removal and reinstallation.\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\u003eHead Style\u003c\/strong\u003e: Headless\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 21\/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: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 3\/8 inches\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\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: P486IU\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51740105507122,"sku":"P486IU","price":16.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/79c55b9503f5b2b51a95049f224e918b_5a372764-c241-4d91-aa06-915780e7ff2f.jpg?v=1788822342","url":"https:\/\/voomisupply.com\/products\/boneham-p486iu-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
