With an inside diameter of 0.377 inches (Letter size V, Wire size P) and a body outside diameter of 3\/4 inch, this bushing provides accurate hole location and consistent tool guidance across production runs. The overall bushing length is 3\/8 inch. Hardness is rated at 60 to 65 HRC, making it suitable for repetitive drilling operations where wear resistance is critical. It is a non-renewable, headless design installed via press fit into a drill jig plate or fixture body. Machinists, toolmakers, and fixture builders are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis bushing is used in manufacturing and fabrication environments where precise drill guidance is required. Typical applications include production drilling jigs, assembly fixtures, and inspection fixtures in machine shops and metalworking facilities. The headless profile sits flush with the jig plate surface, making it appropriate for close-clearance layouts where a flanged head would interfere with workpiece access or adjacent bushings. It is well-suited for both low-volume prototype tooling and high-volume production fixture applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation — no set screws or retaining hardware required\u003c\/li\u003e\n  \u003cli\u003eHeadless design sits flush with jig plate surface for close-clearance layouts\u003c\/li\u003e\n  \u003cli\u003e60 to 65 HRC hardness for extended wear life in repetitive drilling operations\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of +0.0001 to +0.0005 inches ensures accurate tool guidance\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in metalworking fixture environments\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards for drill bushing dimensions and tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation drill bushing for standard press fit headless bushing applications conforming to ANSI drill bushing specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by toolmakers or machinists using an arbor press to seat the bushing into a prepared jig plate bore. The receiving bore in the jig plate must be machined to the correct press fit tolerance to ensure proper retention and alignment. Do not hammer the bushing directly without a proper driver or press — doing so can damage the bushing bore or distort the outer diameter. Because this is a non-renewable bushing, removal typically requires the bushing to be pressed out and replaced.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Decimal)\u003c\/strong\u003e: 0.3770 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Letter Size)\u003c\/strong\u003e: V\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Wire Size)\u003c\/strong\u003e: P\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: 3\/4 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\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 Material\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  \u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: P\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: P486JR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51744950944050,"sku":"P486JR","price":16.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772b15bcdae08b51210f0eebedf78b00_26b4a898-3c14-4a61-a21c-2c538b743ef3.jpg?v=1788862600","url":"https:\/\/voomisupply.com\/products\/boneham-p486jr-press-fit-headless-drill-bushing","provider":"Voomi Supply","version":"1.0","type":"link"}
