Classified under industry code P, this bushing features a 0.272 inch inside diameter with a tight tolerance of +0.0001 to +0.0005 inches, a 7\/16 inch body outside diameter, and a 1 inch overall length. Machined from steel, it provides durable bore guidance under repeated drilling cycles. It is installed without fasteners, relying on an interference press fit to seat securely in a drill jig plate. Machinists and toolmakers specify this bushing type where a flush, unobstructed surface is required above the workpiece.\u003c\/p\u003e\n\u003cp\u003eThis drill bushing is suited for use in production and toolroom environments where consistent hole location accuracy is critical. Typical applications include drilling, reaming, and countersinking operations performed with a drill jig. The headless profile keeps the bushing flush with the jig plate surface, making it appropriate for setups where a headed bushing flange would interfere with the workpiece or clamping fixtures. It is a fixed, non-renewable bushing intended for permanent installation in the jig body.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation — no fasteners required, seats permanently in the jig plate bore\u003c\/li\u003e\n  \u003cli\u003eHeadless design for flush mounting and unobstructed workpiece clearance\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of +0.0001 to +0.0005 inches for precise tool guidance\u003c\/li\u003e\n  \u003cli\u003eIndustry code P classification with 0.272 inch (Letter I) inside diameter\u003c\/li\u003e\n  \u003cli\u003eSteel construction for wear resistance across repeated drilling cycles\u003c\/li\u003e\n  \u003cli\u003eNon-renewable fixed bushing — intended for permanent press fit installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or original-specification drill bushing for jig plates and fixture bodies requiring a headless press fit bushing with a 0.272 inch bore and 7\/16 inch outside diameter.\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 drive the bushing into a precision-reamed hole in the jig plate. The receiving bore in the jig plate must be machined to the correct interference fit tolerance to ensure the bushing seats without distorting the inside diameter. Do not use impact tools to drive the bushing, as this can damage the bore or alter the inside diameter tolerance. Once pressed in, the bushing is not intended for removal or reuse.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Decimal)\u003c\/strong\u003e: 0.2720 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Wire Code)\u003c\/strong\u003e: P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Letter)\u003c\/strong\u003e: I\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: 7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Headless\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Press Fit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\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\u003ePackage Quantity\u003c\/strong\u003e: 1\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: CB00001125\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51748556046642,"sku":"CB00001125","price":17.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/79c55b9503f5b2b51a95049f224e918b_0878763d-befd-47f3-ab7f-8991f321f4d8.jpg?v=1788895183","url":"https:\/\/voomisupply.com\/products\/boneham-cb00001125-headless-drill-bushing-0-272in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
