Manufactured from hardened steel with a surface hardness of 60 to 65 HRC, this bushing provides consistent bore alignment and resists wear over repeated drilling cycles. The headless profile sits flush with the jig plate surface, making it well suited for applications where a protruding head would interfere with workpiece clearance. With an inside diameter of 0.3125 inches and an overall length of 0.75 inches, it delivers reliable guidance in compact fixture setups. Machinists and toolmakers install this type of bushing when building or refurbishing drill jigs that demand repeatable hole location accuracy.\u003c\/p\u003e\n\u003cp\u003eThis bushing is appropriate for use in drill jig plates across light manufacturing, metalworking, and precision machining environments. It is pressed directly into a reamed hole in the jig body and is intended as a permanent, non-renewable installation. The P industry code designates standard press fit headless geometry per ANSI specifications. Typical applications include production drilling fixtures in job shops, toolrooms, and assembly operations where high-volume, consistent hole placement is required. Installation is typically performed by machinists or toolmakers using a press rather than field service trades.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHeadless design sits flush with jig plate for unobstructed workpiece clearance\u003c\/li\u003e\n  \u003cli\u003eHardened steel construction rated 60 to 65 HRC for extended wear life\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of +0.0001 to +0.0005 inches for precise drill guidance\u003c\/li\u003e\n  \u003cli\u003ePress fit installation method provides a secure, permanent fit in the jig body\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards for drill bushing geometry and dimensional consistency\u003c\/li\u003e\n  \u003cli\u003eCompact 0.75 inch overall length suits thin jig plate configurations\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 machined jig plates requiring a 0.5 inch body outside diameter bore and a 0.3125 inch inside guide diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePress fit bushings are installed by machinists using an arbor press or hydraulic press into a precisely reamed jig plate bore. The receiving hole in the jig body must be reamed to the correct interference fit tolerance before installation. Once pressed in, this bushing is not designed for removal or replacement. Always verify bore alignment and bushing seating before committing the jig plate to production use.\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\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\u003eInside Diameter Tolerance\u003c\/strong\u003e: +0.0001 to +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\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\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\u003eWeight\u003c\/strong\u003e: 0.04 pounds\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: P3212IM\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51744539115826,"sku":"P3212IM","price":17.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772b15bcdae08b51210f0eebedf78b00_6d5d9831-83fa-42c3-966f-4fe98f206d2c.jpg?v=1788857780","url":"https:\/\/voomisupply.com\/products\/boneham-p3212im-press-fit-headless-drill-bushing-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
