Built from steel, this Type P headless bushing installs without a head flange, making it well-suited for applications where a flush or recessed seating is required in the jig plate. The inside diameter measures 0.29 inches with a tolerance of +0.0001 to +0.0005 inches, providing a close fit that holds tooling on-center. The body outside diameter is 7\/16 inches and the overall bushing length is 1\/4 inch. Machinists, tool and die makers, and fixture builders are the primary installers of this component.\u003c\/p\u003e\n\u003cp\u003eThis drill bushing is used in drill jigs and fixture tooling across general metalworking, manufacturing, and precision machining environments. The Type P designation and headless profile make it a standard choice for permanent or close-tolerance guiding applications in both production and prototype settings where a retainer or lock collar is not required and a clean, low-profile installation is preferred. It is sold individually and carries a minimum order quantity of one piece.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation method for secure, interference-fit seating in jig plate bores\u003c\/li\u003e\n  \u003cli\u003eHeadless design provides a flush or below-surface profile with no flange interference\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 0.29 inches with a precision tolerance of +0.0001 to +0.0005 inches\u003c\/li\u003e\n  \u003cli\u003eBody outside diameter of 7\/16 inches and overall length of 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability and wear resistance in repeated drilling applications\u003c\/li\u003e\n  \u003cli\u003eBushing Industry Code P designation for standardized identification and replacement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or standard fit component for drill jigs and tooling fixtures requiring a Type P headless press fit bushing with a 0.29-inch inside diameter and 7\/16-inch outside diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePress fit drill bushings are installed by toolmakers or machinists using an arbor press to drive the bushing squarely into a precision-reamed bore in the jig plate. The receiving bore must be machined to the correct diameter to achieve the required interference fit before pressing the bushing in place. Do not hammer the bushing directly without a driver or press tool, as this can damage the bore or distort the bushing. Once pressed in, this 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\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: 0.2900 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Letter)\u003c\/strong\u003e: L\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\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRenewable Bushing\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\u003eUNSPSC Code\u003c\/strong\u003e: 31171603\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: PT284IB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51754924048690,"sku":"PT284IB","price":15.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da93884d577e90ae13b1332b9b2bc4d1.jpg?v=1788949830","url":"https:\/\/voomisupply.com\/products\/boneham-pt284ib-headless-drill-bushing-0-29-in-id-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
