Built to industry code P, this bushing features a 0.4375-inch inside diameter, a 0.75-inch outside diameter, and a 0.5-inch overall length. Manufactured from steel and hardened to 60 to 65 HRC, it provides the wear resistance needed for repetitive production drilling. The headless design allows the bushing to sit flush within a plate or fixture body without a protruding flange. Installation is by press fit, making it a permanent, non-renewable bushing. It conforms to ANSI standards.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for use in drill jigs, fixtures, and production tooling setups found in machine shops and metalworking environments. It is installed by toolmakers and machinists who require repeatable hole location accuracy across multiple workpieces. The P series headless press fit style is a common specification in both manual and CNC-assisted drilling operations where a permanent bushing without a collar is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePress fit installation for permanent, fixed positioning in jig plates\u003c\/li\u003e\n\u003cli\u003eHeadless design sits flush with the fixture surface\u003c\/li\u003e\n\u003cli\u003eSteel construction hardened to 60 to 65 HRC for extended wear life\u003c\/li\u003e\n\u003cli\u003eInside diameter tolerance of +0.0001 to +0.0005 inches for precise tool guidance\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI standards for industry-standard interchangeability\u003c\/li\u003e\n\u003cli\u003eBushing industry code P for straightforward cross-referencing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an ANSI-standard P-series press fit headless drill bushing for use in drill jigs and machining fixtures requiring a 0.4375-inch inside diameter and 0.75-inch outside diameter permanent bushing.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePress fit bushings are installed by toolmakers or machinists using an arbor press to drive the bushing flush into a bored hole in the jig plate. The receiving hole must be machined to the appropriate interference fit tolerance to ensure the bushing remains stationary during use. This is a non-renewable bushing and is not intended for removal or replacement after installation. Verify bore and bushing dimensions before pressing to avoid damaging the bushing or fixture plate.\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\u003eInside Diameter\u003c\/strong\u003e: 0.4375 inches\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: 0.5 inches\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\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\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: P488KQ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51741423305010,"sku":"P488KQ","price":16.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772b15bcdae08b51210f0eebedf78b00_65457d56-25b3-45be-a941-b9b142a88ac9.jpg?v=1788831435","url":"https:\/\/voomisupply.com\/products\/boneham-p488kq-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
