Manufactured from steel with a hardness rating of 60 to 65 HRC, this bushing delivers the wear resistance required for repeated production runs. The SF4828LP features a 33\/64 inch inside diameter, a 3\/4 inch body outside diameter, and a 1-3\/4 inch length under the head. It installs into a drill jig plate using the slip-fixed method, allowing quick tool changes while maintaining precise hole location. Installation is compatible with the LS-1 lock screw for secure retention during use.\u003c\/p\u003e\n\u003cp\u003eThis slip-fixed bushing is suited for use in drill jigs across tool-and-die, production machining, and fabrication environments. The headed design seats flush against the jig plate, providing a positive stop and consistent depth reference. The renewable bushing construction allows worn bushings to be replaced without scrapping the jig body, making the SF4828LP practical for high-cycle production fixtures. It meets ANSI standards, which is the governing specification for drill jig bushings in North American manufacturing shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSlip-fixed installation method allows quick bushing changes during production runs\u003c\/li\u003e\n  \u003cli\u003e33\/64 inch inside diameter with a tolerance of +0.0001 to +0.0005 inches for precise tool guidance\u003c\/li\u003e\n  \u003cli\u003eSteel construction hardened to 60 to 65 HRC for extended wear life\u003c\/li\u003e\n  \u003cli\u003eHeaded design provides a positive seating reference against the jig plate\u003c\/li\u003e\n  \u003cli\u003eRenewable bushing construction supports in-place replacement without jig rework\u003c\/li\u003e\n  \u003cli\u003eLS-1 lock screw compatible for positive retention\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards for drill jig bushings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ANSI-standard slip-fixed drill bushing compatible with LS-1 lock screws and suitable for use in standard drill jig liner bushings sized for a 3\/4 inch body outside diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eSlip-fixed bushings are installed and removed by machinists or toolmakers using standard jig bushing installation tools. Ensure the mating liner bushing bore and jig plate are clean and free of chips before seating the bushing. Secure the bushing with the appropriate LS-1 lock screw to prevent rotation or pullout during cutting operations. Do not force the bushing into an undersized liner, as this can damage the bore tolerance and compromise hole location accuracy.\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: 0.7500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 1-3\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 1\/4 inch\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\u003eInstallation Method\u003c\/strong\u003e: Slip-Fixed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: SF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLock Screw Compatibility\u003c\/strong\u003e: LS-1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Configuration\u003c\/strong\u003e: Head\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCounterbored\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRenewable\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\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: SF4828LP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51729456431410,"sku":"SF4828LP","price":30.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d089b0a7b36c5d4ca8f716b32e5b0d8a_62b045ce-6cc5-4a7d-882c-f50164b1887c.jpg?v=1788704850","url":"https:\/\/voomisupply.com\/products\/boneham-sf4828lp-slip-fixed-drill-bushing-33-64-in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
