Built to ANSI standards, this bushing features a 0.1495 inch inside diameter (wire size No. 25) and a 0.500 inch body outside diameter with a 0.500 inch length under head. Constructed from hardened steel at 60 to 65 HRC, it provides the wear resistance required for repetitive production drilling. The head style design and LS-1 lock screw compatibility allow secure, positive retention in a drill jig or fixture plate. This is a renewable bushing, meaning it can be replaced in the liner without removing the liner from the fixture.\u003c\/p\u003e\n\u003cp\u003eSlip-fixed drill bushings like the SF328EN are used in production jig drilling applications across metalworking, tooling, and fabrication environments. The SF industry code designates this as a slip-type bushing that locks in place via a lock screw, making it well suited for operations requiring tool changes or bushing swaps between operations at the same drill point. Machinists, toolmakers, and jig and fixture builders are the primary installers. This part is compatible with LS-1 lock screws and fits standard ANSI slip-fixed liner configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.1495 inch ID (wire size No. 25) with a tight tolerance of +0.0001 to +0.0004 inch for accurate tool guidance\u003c\/li\u003e\n  \u003cli\u003eHardened steel construction at 60 to 65 HRC for extended service life in production drilling\u003c\/li\u003e\n  \u003cli\u003eHead OD of 51\/64 inch and head height of 1\/4 inch for positive seating in jig plates\u003c\/li\u003e\n  \u003cli\u003eRenewable design allows bushing replacement without disturbing the liner\u003c\/li\u003e\n  \u003cli\u003eLS-1 lock screw compatible for secure slip-fixed retention\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 for use with LS-1 compatible lock screws and standard ANSI slip-fixed liner bushings in drill jig and fixture applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by toolmakers or machinists during jig and fixture assembly or maintenance. Ensure the liner bushing bore and the fixture plate are clean and free of chips before inserting the slip-fixed bushing. The lock screw must be engaged to secure the bushing during drilling operations. Always verify the drill press or machine is powered down and locked out before servicing or replacing bushings in a fixture.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Decimal)\u003c\/strong\u003e: 0.1495 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Wire Size)\u003c\/strong\u003e: No. 25\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: 0.500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 0.500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 51\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Style\u003c\/strong\u003e: Head\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\u003eLock Screw Compatibility\u003c\/strong\u003e: LS-1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRenewable Bushing\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCounterbored\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: SF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\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: SF328EN\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51744971817266,"sku":"SF328EN","price":23.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d089b0a7b36c5d4ca8f716b32e5b0d8a_ee149ccd-7fdc-471e-8da5-4536301c3c5f.jpg?v=1788862826","url":"https:\/\/voomisupply.com\/products\/boneham-sf328en-slip-fixed-drill-bushing-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
