Built to industry code P, this bushing features a 17\/64-inch inside diameter and a 1\/2-inch outside diameter, with an overall length of 3\/4 inch. Constructed from steel, it is pressed directly into a jig plate or fixture without a head flange, keeping the bushing flush with the work surface. Machinists and toolmakers install these bushings to maintain hole location accuracy across repeated drilling operations.\u003c\/p\u003e\u003cp\u003eThe P3212HN is suited for use in drill jig fixtures in production machining environments, tool rooms, and fabrication shops. Its headless design makes it appropriate for applications where a flush or recessed bushing face is required and where a flange would interfere with the workpiece or fixture layout. The press fit installation method locks the bushing firmly into the jig plate without additional fasteners.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHeadless press fit design seats flush with the jig plate surface\u003c\/li\u003e\n\u003cli\u003e17\/64-inch inside diameter with a tight tolerance of +0.0001 to +0.0005 inches for precise tool guidance\u003c\/li\u003e\n\u003cli\u003e1\/2-inch body outside diameter for secure press fit retention\u003c\/li\u003e\n\u003cli\u003e3\/4-inch overall bushing length provides adequate tool guide depth\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability in repeated drilling applications\u003c\/li\u003e\n\u003cli\u003eNon-renewable design for permanent fixture installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation drill bushing for standard P-series press fit headless bushing applications in drill jig fixtures.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePress fit bushings are installed by machinists or toolmakers using an arbor press or hydraulic press to seat the bushing into a properly reamed hole in the jig plate. Ensure the receiving hole in the fixture is reamed to the correct tolerance to achieve proper press fit interference. Do not hammer the bushing in freehand, as this can damage the bore or cause misalignment. Follow applicable shop standards and fixture design specifications for bushing installation and replacement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 17\/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: 1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Headless\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Press Fit\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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: P3212HN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51748721361202,"sku":"P3212HN","price":18.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7b5c1ba9c7a9d7cd0136ad4f7f1577c8.jpg?v=1788897285","url":"https:\/\/voomisupply.com\/products\/boneham-p3212hn-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
