Manufactured from steel with a hardness of 60 to 65 HRC, this bushing maintains tight bore tolerances to keep tooling on location during drilling operations. The inside diameter measures 0.257 inches with an inside diameter tolerance of plus 0.0001 to plus 0.0005 inches, and the body outside diameter is 0.5 inches. Machinists, toolmakers, and production line technicians install this type of bushing when setting up drill jigs for repeatable hole placement across multiple workpieces.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for use in drill jigs and fixture plates in both job shop and production environments. The headless design allows the bushing to sit flush within the jig plate, making it appropriate for applications where a protruding head would interfere with the workpiece or clamping setup. The press fit installation method secures the bushing directly into a reamed hole in the jig body without additional fasteners. Industry code P identifies the bushing series per ANSI standards, helping tooling engineers cross-reference and source the correct replacement or original component for a given jig design.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation into reamed jig plate holes — no fasteners required\u003c\/li\u003e\n  \u003cli\u003eHeadless design sits flush with jig plate surface for unobstructed workpiece contact\u003c\/li\u003e\n  \u003cli\u003eSteel construction hardened to 60 to 65 HRC for wear resistance under repeated drilling cycles\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of plus 0.0001 to plus 0.0005 inches for consistent tool guidance\u003c\/li\u003e\n  \u003cli\u003eANSI-standard bushing industry code P for straightforward cross-reference and sourcing\u003c\/li\u003e\n  \u003cli\u003eNon-renewable design — intended as a permanent press fit installation\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 0.5 inch outside diameter bushing bore and a 0.257 inch inside diameter tool passage.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolmakers using a press or arbor press to seat the bushing into a precision-reamed hole in the jig plate. The receiving hole in the jig body must be reamed to the appropriate press fit tolerance for the 0.5 inch outside diameter before installation. Do not hammer the bushing in freehand, as this can damage the bore or misalign the bushing. Once pressed in, the bushing is not designed for removal and reuse.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Decimal Inch)\u003c\/strong\u003e: 0.257 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Letter)\u003c\/strong\u003e: F\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: 0.5 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\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\u003eBushing Material\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: CB00001118\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51738199654706,"sku":"CB00001118","price":15.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772b15bcdae08b51210f0eebedf78b00_4bbbbdc0-5463-410f-9c6f-d0363e365982.jpg?v=1788796691","url":"https:\/\/voomisupply.com\/products\/boneham-cb00001118-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
