This bushing carries industry code P and features a 0.238 inch inside diameter with an inside diameter tolerance of +0.0001 to +0.0004 inches, a 0.5 inch outside diameter, and a 1 inch overall length. Manufactured from steel, it is designed for permanent installation in drill jig applications where tool-guidance accuracy and wear resistance are required. It is installed without a head, making it flush-mount suitable when a low-profile installation is needed. Machinists, toolmakers, and fixture builders are the primary installers of this component.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for use in production and inspection jigs where consistent hole location is critical across repeated drilling operations. The press fit installation method means it is driven or pressed directly into a prepared hole in the jig plate, providing a rigid, non-rotating fit. It is appropriate for light to medium-duty drilling applications in both job shop and production environments. The headless design allows the bushing to sit flush with or below the surface of the jig plate, which is useful in applications where clearance above the plate surface is limited.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIndustry code P press fit headless configuration for permanent jig installation\u003c\/li\u003e\n\u003cli\u003e0.238 inch inside diameter with tight tolerance of +0.0001 to +0.0004 inches for precise tool guidance\u003c\/li\u003e\n\u003cli\u003e0.5 inch outside diameter and 1 inch overall length for standard jig plate fitment\u003c\/li\u003e\n\u003cli\u003eSteel construction provides wear resistance and durability under repeated drilling cycles\u003c\/li\u003e\n\u003cli\u003eHeadless design allows flush or sub-flush mounting in jig plates with limited clearance\u003c\/li\u003e\n\u003cli\u003eNon-renewable bushing intended for fixed, long-term installation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation drill bushing for standard press fit headless bushing applications in steel drill jigs and fixtures conforming to industry code P specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by toolmakers or machinists using an arbor press or hydraulic press to drive the bushing into a precision-reamed hole in the jig plate. The receiving hole must be sized to the bushing outside diameter tolerance to achieve the correct press fit interference. Do not use a hammer directly on the bushing face, as this can damage the bore or distort the bushing. Verify inside diameter clearance for the intended drill or tool shank before pressing the bushing into place, as this bushing is non-renewable and not designed for removal and reinstallation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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\u003eInside Diameter (Decimal)\u003c\/strong\u003e: 0.2380 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter (Letter)\u003c\/strong\u003e: B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter (Wire)\u003c\/strong\u003e: 0.238 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: +0.0001 to +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: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Material\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\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: CB00001108\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51733463826738,"sku":"CB00001108","price":15.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/79c55b9503f5b2b51a95049f224e918b_fb566d00-cf88-4ad9-8dd2-2c2b643561bf.jpg?v=1788755664","url":"https:\/\/voomisupply.com\/products\/boneham-cb00001108-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
