Manufactured from steel with a hardness rating of 60 to 65 HRC, this bushing resists wear under repeated drilling cycles. The inside diameter is 0.052 inches (Wire size No. 55) with a tolerance of +0.0001 to +0.0004 inches, ensuring close control over tool alignment. The body outside diameter is 0.1875 inches (3\/16 inches) and the overall bushing length is 0.3125 inches (5\/16 inches). It installs by press fit into a prepared bore and requires no head or locking collar. Machinists, toolmakers, and fixture builders work with this component in precision metalworking environments.\u003c\/p\u003e\u003cp\u003eThis bushing suits applications where a low-profile, headless design is required and the bushing must sit flush with or below the jig plate surface. Industry code P designates its press fit, non-renewable classification under standard jig bushing nomenclature. Typical use cases include production drilling jigs, assembly fixtures, and template guides in light to medium manufacturing. Because the bushing is not renewable, it is intended for permanent installation in the fixture plate for the life of the tool or fixture.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePress fit installation — no head or retaining collar required for a flush, low-profile mount\u003c\/li\u003e\n\u003cli\u003eSteel construction hardened to 60 to 65 HRC for wear resistance under repeated tool passes\u003c\/li\u003e\n\u003cli\u003eInside diameter tolerance of +0.0001 to +0.0004 inches for precise tool guidance\u003c\/li\u003e\n\u003cli\u003eHeadless design allows the bushing to seat fully below or flush with the jig plate surface\u003c\/li\u003e\n\u003cli\u003eMeets ANSI standards for jig bushing dimensions and tolerances\u003c\/li\u003e\n\u003cli\u003eIndustry code P classification — non-renewable, permanent-install type\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an ANSI-standard press fit headless drill bushing for use in machining jigs, drilling fixtures, and tooling plates requiring a No. 55 wire-size bore guide.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or toolmaker using an arbor press to drive the bushing into a properly reamed bore in the fixture plate. The receiving bore must be machined to the correct press fit tolerance to achieve proper retention — do not hammer the bushing in freehand. Because this is a non-renewable bushing, removal will damage either the bushing or the plate. Ensure the fixture plate is secured and supported squarely during pressing to prevent bore distortion.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Press Fit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter (Wire Size)\u003c\/strong\u003e: No. 55\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter (Decimal)\u003c\/strong\u003e: 0.052 inches\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: 0.1875 inches (3\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 0.3125 inches (5\/16 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: PT125BJ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51738707099954,"sku":"PT125BJ","price":30.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772b15bcdae08b51210f0eebedf78b00_b9c6557a-b529-43b3-bae0-fbf842497881.jpg?v=1788803148","url":"https:\/\/voomisupply.com\/products\/boneham-pt125bj-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
