Machined from steel and hardened to 60 to 65 HRC, this bushing resists wear under repeated drilling cycles. It carries an inside diameter of 41\/64 inches with a tight tolerance of plus 0.0001 to plus 0.0005 inches, a body outside diameter of 7\/8 inches, and an overall length of 3\/4 inches. The headless design allows flush or sub-flush seating where a flanged head would interfere with the workpiece or mating fixture components. Machinists, toolmakers, and fixture builders install this type of bushing in production and maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for use in drill jigs where a permanent, non-renewable guide is acceptable. The press fit installation method means the bushing is driven or pressed into a prepared hole in the jig body and is intended to remain fixed for the service life of the fixture. Industry code P identifies the bushing family per ANSI standards, making it straightforward to cross-reference against standard jig bushing charts. Typical applications include repetitive hole-location work in metal fabrication, aerospace tooling, and general manufacturing fixtures requiring consistent drill entry points.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHeadless design allows flush seating in close-clearance fixture layouts\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 0.0005 inches for precise tool guidance\u003c\/li\u003e\n  \u003cli\u003ePress fit installation — no locking hardware required\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards for drill bushing geometry and dimensional compliance\u003c\/li\u003e\n  \u003cli\u003eNon-renewable fixed bushing suitable for high-volume, single-location jig setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ANSI-standard industry code P press fit headless drill bushing, compatible with jig plates and fixture bodies bored to accept a 7\/8-inch outside diameter press fit bushing per standard jig bushing tolerancing practices.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolmakers using an arbor press or hydraulic press to seat the bushing into a precision-bored jig plate. The receiving bore must be machined to the correct interference fit per ANSI jig bushing standards before installation. Once pressed in, this bushing is not designed for removal and reuse. Verify bore alignment and cleanliness before pressing to avoid damage to the bushing or host fixture.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 41\/64 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\u003eBody Outside Diameter\u003c\/strong\u003e: 7\/8 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\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\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\u003eBushing Industry Code\u003c\/strong\u003e: P\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: P5612MK\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51754946560306,"sku":"P5612MK","price":18.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772b15bcdae08b51210f0eebedf78b00_6c682c43-0ef7-47d6-a54f-7c60f28e50b1.jpg?v=1788950054","url":"https:\/\/voomisupply.com\/products\/boneham-p5612mk-headless-drill-bushing-41-64-in-id-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
