Built to Industry Code P, this bushing features a 0.75-inch (3\/4 inch) inside diameter and a 1-inch outside diameter, with an overall length of 0.5 inches. Manufactured from hardened steel with a Rockwell hardness of 60 to 65 HRC, it delivers consistent bore alignment and resistance to wear under repeated drilling cycles. Machinists, tool-and-die makers, and production technicians install this type of bushing where accurate, repeatable hole location is required.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for use in drill jigs and production fixtures across light manufacturing, metalworking, and machine shop environments. The headless design allows the bushing to sit flush within the jig plate, making it appropriate where a protruding flange would interfere with the workpiece or adjacent tooling. The press fit installation method ensures the bushing is retained securely in the jig body without additional fasteners. It conforms to ANSI standards for drill bushing geometry and tolerances.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePress fit installation — no fasteners required for retention in the jig plate\u003c\/li\u003e\n\u003cli\u003eHeadless design sits flush with the jig plate surface for unobstructed workpiece contact\u003c\/li\u003e\n\u003cli\u003e0.75-inch ID with a tolerance of +0.0001 to +0.0005 inches for precise tool guidance\u003c\/li\u003e\n\u003cli\u003eHardened steel construction at 60 to 65 HRC for long service life under repeated drilling cycles\u003c\/li\u003e\n\u003cli\u003eMeets ANSI standards for drill bushing dimensions and tolerances\u003c\/li\u003e\n\u003cli\u003eIndustry Code P for straightforward cross-referencing and replacement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an ANSI-standard Industry Code P press fit headless drill bushing, suitable for use in drill jigs and fixtures that accept a 1-inch outside diameter press fit bushing with a 0.75-inch bore.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by pressing the bushing into a precisely reamed or bored hole in the jig plate using an arbor press or hydraulic press — never drive with a hammer directly on the bushing bore. Ensure the receiving hole diameter and finish match the press fit tolerance requirements before installation. Power down all machinery and secure the workpiece before servicing or replacing bushings in an active fixture. Removal typically requires a bushing driver or extraction tool to avoid damaging the jig plate bore.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.75 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: 1 inch\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\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\u003eBushing Industry Code\u003c\/strong\u003e: P\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 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\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: P648NC\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51737372361010,"sku":"P648NC","price":19.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772b15bcdae08b51210f0eebedf78b00_efc8a1cf-bb8b-4234-81fa-42b45b1eb093.jpg?v=1788787749","url":"https:\/\/voomisupply.com\/products\/boneham-p648nc-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
