It carries an inside diameter of 0.386 inches (Letter W, Decimal 0.3860 inches) with a body outside diameter of 3\/4 inches and an overall length of 5\/16 inches. Machined from steel, this bushing is installed without a head, sitting flush within the drill jig plate. The bore holds a tight inside diameter tolerance of plus 0.0001 to plus 0.0005 inches, keeping tool runout minimal and hole placement repeatable. Machinists, tool-and-die makers, and production line technicians install this type of component during fixture setup or jig maintenance.\u003c\/p\u003e\n\u003cp\u003eThis bushing suits applications where a permanent, non-renewable press fit installation is required in a steel or hardened jig plate. It is appropriate for production drilling, reaming, and light boring operations in both job-shop and manufacturing environments. The headless design allows flush mounting in close-tolerance jig plates where a flanged head would interfere with workpiece seating or clearance. Industry code P identifies the bushing series, allowing straightforward cross-reference with standard drill bushing specifications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInside diameter of 0.386 inches (Letter W) with tolerance of plus 0.0001 to plus 0.0005 inches for precise tool guidance\u003c\/li\u003e\n  \u003cli\u003eBody outside diameter of 3\/4 inches and overall length of 5\/16 inches for compact jig plate integration\u003c\/li\u003e\n  \u003cli\u003eHeadless design allows flush installation where flange clearance is not available\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability under repeated drilling and reaming cycles\u003c\/li\u003e\n  \u003cli\u003ePress fit installation method creates a permanent, non-renewable mount — no locking hardware required\u003c\/li\u003e\n  \u003cli\u003eBushing Industry Code P for straightforward catalog cross-reference\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation drill bushing for standard P-series jig and fixture plates requiring a press fit headless bushing with a 3\/4 inch outside diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePress fit headless drill bushings are typically installed by machinists or tool-and-die technicians using an arbor press or hydraulic press to drive the bushing into a pre-reamed jig plate hole. Ensure the receiving hole in the jig plate is reamed to the correct fit class before pressing the bushing into place. Because this is a non-renewable bushing, removal will likely damage the bushing or the jig plate bore. Always de-burr and clean the receiving hole before installation to avoid galling the bushing or distorting the inside diameter tolerance.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Decimal)\u003c\/strong\u003e: 0.3860 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Letter)\u003c\/strong\u003e: W\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: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 5\/16 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\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\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: P485JW\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51737721766194,"sku":"P485JW","price":16.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/79c55b9503f5b2b51a95049f224e918b_9ce7eb46-c3fb-480e-9108-1ef4831ec7d1.jpg?v=1788792783","url":"https:\/\/voomisupply.com\/products\/boneham-p485jw-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
