Machined from steel, this type P bushing features an inside diameter of 0.086 inches (wire size number 44) and a body outside diameter of 3\/16 inches. The press fit installation method locks the bushing directly into the jig plate without a head flange, keeping the top surface flush. Overall bushing length is 5\/8 inches. Inside diameter tolerance is held to a close +0.0001 to +0.0004 inches, ensuring repeatable hole location across production runs. Machinists, tool and die makers, and fixture builders install this component in drill jigs and tooling fixtures.\u003c\/p\u003e\n\u003cp\u003eThis bushing suits metal fabrication, machining, and assembly fixture applications where a permanent, non-renewable guide bushing is required. The headless design is appropriate when the bushing must sit flush with or below the jig plate surface, avoiding interference with workpiece clamping or part clearance. It is a fixed, non-renewable bushing, meaning it is pressed in for long-term service rather than swapped out between operations. Typical installations include production drill jigs used in metalworking shops, maintenance and repair tooling, and custom fixture builds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation seats bushing permanently in jig plate bore without fasteners\u003c\/li\u003e\n  \u003cli\u003eHeadless body profile keeps bushing flush with plate surface for unobstructed clamping\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of +0.0001 to +0.0004 inches provides precise tool guidance\u003c\/li\u003e\n  \u003cli\u003eSteel construction delivers durability under repeated drilling cycles\u003c\/li\u003e\n  \u003cli\u003eIndustry code P designation confirms compliance with standard drill bushing sizing\u003c\/li\u003e\n  \u003cli\u003eNon-renewable fixed design suited for high-volume production jigs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard type P headless press fit drill bushing for use in drill jigs and machining fixtures requiring a 3\/16 inch outside diameter press fit bore and a 0.086 inch inside diameter tool guide.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePress fit bushings are installed by machinists or toolmakers using an arbor press or hydraulic press; never drive the bushing in with a hammer directly, as this risks distorting the bore or damaging the jig plate. The receiving bore in the jig plate must be machined to the appropriate press fit tolerance before installation. Once pressed in, the bushing is not intended for removal or replacement. Always verify inside diameter after pressing to confirm the bore has not closed beyond the specified tolerance range.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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 (Decimal)\u003c\/strong\u003e: 0.086 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Wire Size)\u003c\/strong\u003e: Number 44\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: +0.0001 to +0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 5\/8 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\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: PT1210CN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51732014006578,"sku":"PT1210CN","price":26.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/79c55b9503f5b2b51a95049f224e918b_c86aabbc-5439-44df-b19d-5359c51d5fec.jpg?v=1788738126","url":"https:\/\/voomisupply.com\/products\/boneham-pt1210cn-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
