Manufactured from steel, this bushing features an inside diameter of 0.397 inches (Letter size X, Industry Code P) and a body outside diameter of 0.75 inches. The overall bushing length is 0.25 inches. The press fit design allows for permanent installation in a drill jig plate without a locking head, keeping the jig surface clean and flush. Machinists, tool and die makers, and production shops rely on this style of bushing for high-volume fixture work where consistent hole location is critical.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for use in drill jigs and machining fixtures in both production and job-shop environments. The headless profile makes it appropriate for applications where a flush or recessed installation is required and no bushing renewal is needed. It installs directly into a prepared reamed hole in the jig body. The tight inside diameter tolerance of +0.0001 to +0.0005 inches ensures repeatable tool guidance across high cycle counts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation method for permanent, flush-mount seating in jig plates\u003c\/li\u003e\n  \u003cli\u003eHeadless design provides a clean, unobstructed jig surface\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of +0.0001 to +0.0005 inches for precise tool guidance\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in production drilling applications\u003c\/li\u003e\n  \u003cli\u003eIndustry Code P designation for straightforward catalog cross-referencing\u003c\/li\u003e\n  \u003cli\u003eCompact 0.25-inch overall length suits thin jig plates and close-clearance fixtures\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-build component for standard drill jig fixtures requiring a P-series press fit headless drill bushing with a 0.397-inch inside diameter and 0.75-inch outside diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a machinist or tool maker using an arbor press or hydraulic press to seat the bushing into a precisely reamed hole in the jig plate. The receiving hole should be machined to the appropriate interference fit tolerance before pressing to prevent bushing damage or loosening in service. Do not use a hammer directly on the bushing face. Once pressed in, this bushing is not designed for removal or renewal.\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: 0.3970 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Letter Size\u003c\/strong\u003e: X\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: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 0.25 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\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: P484KA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51730439536946,"sku":"P484KA","price":16.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/79c55b9503f5b2b51a95049f224e918b_f30e713b-8fb8-4e67-b012-244d93e3c316.jpg?v=1788717497","url":"https:\/\/voomisupply.com\/products\/boneham-p484ka-press-fit-headless-drill-bushing-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
