Manufactured from hardened steel with a hardness rating of 60 to 65 HRC, this bushing resists wear under repeated tool cycling. The 0.25-inch inside diameter accepts a size E drill or equivalent tooling, while the 0.5-inch outside diameter provides a stable press fit into a jig plate or fixture body. The 0.375-inch overall length suits compact fixture designs where head clearance is not available. Machinists and toolmakers install this bushing as a fixed, non-renewable liner in production jigs and fixtures.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for use in drill jigs, fixture plates, and tooling bodies in both job-shop and production environments. The headless design allows flush seating in applications where a flanged head would interfere with workpiece travel or clamping surfaces. It is appropriate for light to medium drilling cycles where the bushing is intended to remain in the fixture for the life of the jig rather than be replaced between runs. Typical users include machinists, tool and die makers, and fixture builders working to ANSI jig bushing standards.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation — no fasteners or locking collars required\u003c\/li\u003e\n  \u003cli\u003eHeadless profile allows flush mounting where flanges would obstruct workpieces or clamps\u003c\/li\u003e\n  \u003cli\u003eSteel construction hardened to 60 to 65 HRC for extended wear life under repeated tool contact\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of plus 0.0001 to plus 0.0004 inches for consistent tool guidance\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI jig bushing standards for dimensional interchangeability\u003c\/li\u003e\n  \u003cli\u003eNon-renewable design — intended as a permanent fixture component\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 0.25-inch inside diameter and 0.5-inch outside diameter liner.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePress fit installation is performed by a machinist or toolmaker using an arbor press or hydraulic press. The receiving bore in the jig plate must be machined to the appropriate interference fit tolerance before installation. Once pressed in, the bushing is not intended to be removed or reused. Verify bore alignment and surface finish before pressing to avoid damaging the bushing or distorting the ID.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Letter Size\u003c\/strong\u003e: E\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\u003eBody Outside Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: P\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\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: P326HG\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51755872911666,"sku":"P326HG","price":15.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772b15bcdae08b51210f0eebedf78b00_cc4ff500-2467-4935-99f3-499500954bc3.jpg?v=1788960869","url":"https:\/\/voomisupply.com\/products\/boneham-p326hg-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
