Manufactured from steel and hardened to 60 to 65 HRC, this bushing provides a wear-resistant bore that holds tight tolerances over repeated use. The inside diameter measures 33\/64 inches with a tolerance of +0.0001 to +0.0005 inches, and the body outside diameter is 3\/4 inches. With an overall length of 5\/16 inches, this headless style installs flush without a retaining flange. It is intended for permanent press fit installation into a drill jig plate and is not renewable once pressed in place.\u003c\/p\u003e\n\u003cp\u003eThis bushing suits toolroom, fixture-building, and production drilling operations where consistent hole location is required. The headless P-series design is specified when a low-profile installation is needed and the bushing is not intended to be removed or replaced after installation. Machinists, toolmakers, and fixture designers working to ANSI standards will find this part appropriate for steel or cast jig plates where dimensional accuracy is critical across production runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePress fit installation for permanent, non-renewable seating in jig plates\u003c\/li\u003e\n  \u003cli\u003eHeadless design provides a flush, low-profile installation with no retaining flange\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of +0.0001 to +0.0005 inches ensures consistent tool guidance\u003c\/li\u003e\n  \u003cli\u003eHardness of 60 to 65 HRC delivers extended wear resistance under repeated drilling cycles\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards for drill bushing geometry and dimensional conformance\u003c\/li\u003e\n  \u003cli\u003eSteel construction suited for use in steel and cast jig plate assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a P-series press fit headless drill bushing per ANSI standards, compatible with jig plates and fixture assemblies requiring a 3\/4-inch outside diameter press fit bore and 33\/64-inch inside diameter tool guidance.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by toolmakers or machinists using an arbor press or hydraulic press to seat the bushing flush into the prepared bore of a drill jig plate. The mating bore in the jig plate must be machined to the appropriate interference fit tolerance before installation. Once pressed in, this bushing is not designed to be removed or reused. Power down any associated equipment and secure the fixture before pressing the bushing into place.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 33\/64 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: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Bushing Length\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation Method\u003c\/strong\u003e: Press Fit\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing 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\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\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: P485LP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51746297872690,"sku":"P485LP","price":15.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/772b15bcdae08b51210f0eebedf78b00_6b8a5ff8-151e-41b7-95bf-72cfc58a9220.jpg?v=1788868100","url":"https:\/\/voomisupply.com\/products\/boneham-p485lp-press-fit-headless-drill-bushing-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
