It has a 5\/16 inch (0.3125 inch) inside diameter, a 1\/2 inch outside diameter, and a 3\/8 inch overall length. Hardened to 60-65 HRC, this steel bushing resists wear and maintains hole-location accuracy under repeated use. The headless profile allows the bushing to sit flush in the jig plate, making it well suited for applications where a protruding flange would interfere with the workpiece or fixturing setup. Machinists and tool-and-die professionals install this type of bushing into drill jigs, fixtures, and templates.\u003c\/p\u003e\n\u003cp\u003eThis bushing is intended for use in drill jig plates in industrial machining, metalworking, and precision fabrication environments. The press fit installation method locks the bushing permanently into the jig plate bore without the need for additional locking hardware or a liner bushing. It is classified under Industry Code P and meets ANSI standards for drill bushing dimensions and tolerances. Inside diameter tolerance is held to +0.0001 to +0.0005 inches, supporting close-tolerance drilling and reaming operations in production or job-shop settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHeadless press fit design installs flush with the jig plate surface for unobstructed workpiece contact\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of +0.0001 to +0.0005 inches provides close-tolerance tool guidance\u003c\/li\u003e\n  \u003cli\u003eHardness of 60 to 65 HRC for extended wear life under high-cycle drilling\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in metalworking and fabrication applications\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards for drill bushing dimensional conformance\u003c\/li\u003e\n  \u003cli\u003ePermanent installation — not renewable, eliminates the need for a liner bushing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ANSI-standard press fit headless drill bushing for use in drill jigs and fixtures requiring a 5\/16 inch bore guide with a 1\/2 inch outside diameter and 3\/8 inch overall length.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolmakers using an arbor press to drive the bushing into a pre-bored jig plate hole sized for an interference fit. Power down all machinery and secure the workholding fixture before pressing the bushing into place. Do not use a hammer directly on the bushing face, as this can damage the bore tolerance. 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\u003eInside Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 3\/8 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\u003eHardness\u003c\/strong\u003e: 60 to 65 HRC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\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\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\u003eBushing Industry Code\u003c\/strong\u003e: P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\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: P326IM\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51731466518834,"sku":"P326IM","price":16.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772b15bcdae08b51210f0eebedf78b00_80b05be6-ad85-49de-b7ae-8768aa589dff.jpg?v=1788731451","url":"https:\/\/voomisupply.com\/products\/boneham-p326im-press-fit-headless-drill-bushing-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
