With a 0.29 inch inside diameter and a 0.5 inch outside diameter, this bushing guides drill bits, reamers, and other cutting tools to maintain accurate hole location and alignment. The overall length is 0.75 inches. Hardness runs 60 to 65 HRC, which provides the wear resistance required in high-cycle production jigs and fixtures. This is a non-renewable, permanently installed bushing conforming to ANSI standards. It is installed by machinists, toolmakers, and fixture builders in manufacturing and fabrication environments.\u003c\/p\u003e\n\u003cp\u003eThe P3212IB fits applications where a permanent, low-profile bushing is required in a drill jig, fixture plate, or tooling block. The headless profile sits flush with the jig plate surface, making it well suited for close-tolerance work where a flanged head would interfere with the workpiece or clamping arrangement. Inside diameter tolerance is held to plus 0.0001 to plus 0.0005 inches, ensuring consistent tool guidance across repeated operations. Typical users include tool and die shops, production machinists, and precision fabricators working with steel or aluminum fixtures.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation — no retaining hardware required once seated in the jig plate\u003c\/li\u003e\n  \u003cli\u003eHeadless design sits flush with the jig plate surface to avoid workpiece interference\u003c\/li\u003e\n  \u003cli\u003eHardened steel construction rated 60 to 65 HRC for extended wear life in high-cycle applications\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of plus 0.0001 to plus 0.0005 inches for precise tool guidance\u003c\/li\u003e\n  \u003cli\u003eANSI-conforming dimensions for interchangeability with standard jig bushing tooling\u003c\/li\u003e\n  \u003cli\u003eNon-renewable design for permanent fixture installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style press fit headless drill bushing conforming to ANSI standards, suitable for use in standard drill jig plates and fixture tooling that accept a 0.5 inch outside diameter bushing with a 0.75 inch overall length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePress fit bushings are installed by toolmakers or machinists using an arbor press or hydraulic press to seat the bushing flush and square in the jig plate bore. The receiving bore must be machined to the correct interference fit tolerance before installation. Once pressed in, the bushing is not intended to be removed or replaced. Always verify bore diameter and finish before pressing to avoid galling or bushing damage.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.29 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Decimal\u003c\/strong\u003e: 0.2900 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Letter Size\u003c\/strong\u003e: L\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 0.5 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\u003eInside Diameter Tolerance\u003c\/strong\u003e: plus 0.0001 to plus 0.0005 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\u003eBushing Material\u003c\/strong\u003e: Steel\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\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\u003eBushing Industry Code\u003c\/strong\u003e: P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\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: P3212IB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51728472604978,"sku":"P3212IB","price":18.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772b15bcdae08b51210f0eebedf78b00_1c06d69b-cb6f-43be-be70-ad3224511696.jpg?v=1788691758","url":"https:\/\/voomisupply.com\/products\/boneham-p3212ib-press-fit-headless-drill-bushing-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
