It is manufactured from steel and hardened to 60 to 65 HRC, providing a wear-resistant guide bore for precision drilling operations. The inside diameter measures 0.3125 inches with a tight tolerance of +0.0001 to +0.0005 inches, ensuring accurate bit guidance. The body outside diameter is 5\/8 inches and the overall length is 3\/8 inches. This bushing is a fixed, non-renewable type intended for permanent installation in drill jigs and fixtures used in machining, fabrication, and tooling applications.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for use in drill jigs where a permanent, flush-mounted guide is required. The headless design seats flush with the jig plate surface, making it appropriate for close-clearance applications where a flanged head would interfere with workpiece access or fixture stack-up. Machinists, tool and die makers, and precision fabricators typically install this type of bushing in production jig plates to maintain consistent hole location across repeated drilling cycles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation  -  permanent, non-renewable fixed bushing design\u003c\/li\u003e\n  \u003cli\u003eHardness of 60 to 65 HRC for extended wear life under continuous drilling use\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of +0.0001 to +0.0005 inches for precise bit guidance\u003c\/li\u003e\n  \u003cli\u003eHeadless body seats flush with jig plate  -  no flange to interfere with workpiece clearance\u003c\/li\u003e\n  \u003cli\u003eSteel construction meets ANSI drill bushing standards\u003c\/li\u003e\n  \u003cli\u003eBushing Industry Code P classification for straightforward replacement identification\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 for use in drill jigs and fixture plates requiring a 5\/8 inches body outside diameter with a 5\/16 inches inside diameter guide bore.\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 similar pressing equipment  -  never drive them in with a hammer, as this can crack or misalign the bushing. The receiving hole in the jig plate must be machined to the correct tolerance to achieve proper interference fit; consult ANSI jig bushing standards for hole preparation requirements. Once pressed in, the P406IM is a permanent installation and is not designed for removal or replacement in service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 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: 5\/8 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\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\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 60 to 65 HRC\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: P406IM\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":67622872154418,"sku":"P406IM","price":16.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772b15bcdae08b51210f0eebedf78b00_3c00f459-8a72-45d2-ace5-a7acf5bbed59.jpg?v=1790441858","url":"https:\/\/voomisupply.com\/products\/boneham-p406im-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
