Built to industry code P, this bushing features a 0.242 inch inside diameter and a 0.5 inch outside diameter, with an overall length of 0.3125 inches. Manufactured from steel and hardened to 60 to 65 HRC, it delivers the wear resistance required for repeated drilling cycles in production environments. The inside diameter is held to a tight tolerance of plus 0.0001 to plus 0.0004 inches, ensuring consistent hole location and drill alignment. Machinists, tool and die makers, and fixture builders install this type of bushing in precision drill jigs.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for use in fixed jig plates where a renewable bushing is not required. The headless design allows it to sit flush with or below the jig plate surface, making it appropriate for applications where a headed bushing would interfere with the workpiece or clamping setup. It is a non-renewable, permanent-press installation intended for moderate to high production drilling, reaming, and boring operations across metalworking and fabrication shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation — no fasteners or locking mechanisms required\u003c\/li\u003e\n  \u003cli\u003eHeadless design sits flush with jig plate surface\u003c\/li\u003e\n  \u003cli\u003eSteel construction hardened to 60 to 65 HRC for extended wear life\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of plus 0.0001 to plus 0.0004 inches for accurate drill guidance\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI standards for drill bushing dimensions and tolerances\u003c\/li\u003e\n  \u003cli\u003eNon-renewable, fixed installation for permanent jig setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ANSI-standard press fit headless drill bushing suitable for use in drill jigs and fixtures requiring a P-series bushing with a 0.242 inch bore and 0.5 inch outside diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a machinist or tool and die maker using an arbor press to drive the bushing into a properly sized jig plate bore. The mating bore in the jig plate must be machined to the correct interference fit to achieve proper retention. Do not hammer the bushing in directly without a press or driver to avoid cocking or damaging the bore. Once pressed in, this bushing is not intended for removal and replacement.\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\u003eInside Diameter (Decimal)\u003c\/strong\u003e: 0.242 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Letter)\u003c\/strong\u003e: C\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: 0.3125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: plus 0.0001 to plus 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\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\u003eStandards\u003c\/strong\u003e: ANSI\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: P325HB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51733473231154,"sku":"P325HB","price":19.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772b15bcdae08b51210f0eebedf78b00_f7df3b03-b8b8-445b-ab6d-26323303ca00.jpg?v=1788755728","url":"https:\/\/voomisupply.com\/products\/boneham-p325hb-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
