Built to ANSI standards, this bushing features a 13\/64 inch inside diameter and a 1\/2 inch outside diameter with a 1\/2 inch overall length. Manufactured from steel and heat-treated to 60 to 65 HRC, it provides long service life in production jig and fixture applications. The inside diameter holds a close tolerance of +0.0001 to +0.0004 inches, ensuring consistent hole location. Machinists, tool and die makers, and fixture builders install this bushing in drill jigs where a permanent, non-renewable liner is required.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for use in drill jigs and tooling fixtures across general metalworking, manufacturing, and precision machining environments. The headless design allows it to sit flush within the jig plate, making it appropriate for applications where a protruding head would interfere with workpiece clearance or fixturing. It is pressed directly into a prepared hole in the jig body without the need for a liner bushing, simplifying fixture construction in lower-volume or permanent setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePress fit installation method — no liner bushing required\u003c\/li\u003e\n\u003cli\u003eHeadless design sits flush with jig plate surface\u003c\/li\u003e\n\u003cli\u003e13\/64 inch ID with +0.0001 to +0.0004 inch tolerance for precise tool guidance\u003c\/li\u003e\n\u003cli\u003eSteel construction hardened to 60 to 65 HRC for wear resistance\u003c\/li\u003e\n\u003cli\u003eMeets ANSI standards for drill bushing dimensions and tolerances\u003c\/li\u003e\n\u003cli\u003eNon-renewable fixed bushing for permanent jig installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation press fit headless drill bushing conforming to ANSI P-series dimensional standards for use in standard drill jig plates and fixtures.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a machinist or toolmaker using an arbor press to seat the bushing flush and square into a precision-reamed hole in the jig plate. The mating hole in the jig body should be machined to the appropriate press fit tolerance before installation. Do not drive the bushing with impact tools, as this can damage the bore or distort the bushing. Once installed, this bushing is not intended for removal or replacement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 13\/64 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: +0.0001 to +0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 60 to 65 HRC\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\u003eHead Style\u003c\/strong\u003e: Headless\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRenewable\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\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: P328GE\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51754421715250,"sku":"P328GE","price":16.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772b15bcdae08b51210f0eebedf78b00_ae20281d-701f-49cf-89ad-40abbf169556.jpg?v=1788945208","url":"https:\/\/voomisupply.com\/products\/boneham-p328ge-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
