Built to industry code SF, this bushing features a 0.209 inch inside diameter and a 0.5 inch body outside diameter, with a head outside diameter of approximately 0.797 inches and a head height of 0.25 inches. The length under head measures 0.3125 inches. Constructed from steel hardened to 60 to 65 HRC, it delivers the wear resistance required for repeated use in production drilling, reaming, and related tooling operations. It is a renewable bushing compatible with LS-1 lock screws and meets ANSI standards.\u003c\/p\u003e\n\u003cp\u003eThis bushing is used in drill jigs and modular fixturing systems where repeatable hole location accuracy is critical. Typical applications include metal fabrication shops, machine shops, and production environments requiring consistent tool guidance across multiple workpieces. The slip-fixed design allows the bushing to be installed and locked in a liner bushing already pressed into the jig plate, making it well suited for operations where the bushing must be changed between operations without removing the liner.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSlip-fixed SF design compatible with standard liner bushings and LS-1 lock screws\u003c\/li\u003e\n  \u003cli\u003e0.209 inch inside diameter with a tight tolerance of plus 0.0001 to plus 0.0004 inches for precise tool guidance\u003c\/li\u003e\n  \u003cli\u003eSteel construction hardened to 60 to 65 HRC for extended service life\u003c\/li\u003e\n  \u003cli\u003eRenewable bushing design allows replacement without disturbing the liner bushing in the jig plate\u003c\/li\u003e\n  \u003cli\u003eHead style for positive axial retention when locked in place\u003c\/li\u003e\n  \u003cli\u003eConforms to 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 ANSI-standard SF slip-fixed drill bushing for use with compatible liner bushings and LS-1 lock screws in standard drill jig and fixture applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by toolmakers or machinist-level personnel using standard jig setup procedures. Ensure the mating liner bushing is properly pressed and seated in the jig plate before inserting this slip-fixed bushing. Secure the bushing with a compatible LS-1 lock screw torqued per shop standards to prevent rotation during cutting operations. Inspect the bushing bore and mating surfaces for wear or damage before each production run.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: SF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Wire)\u003c\/strong\u003e: No. 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Decimal)\u003c\/strong\u003e: 0.209 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: plus 0.0001 to plus 0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 0.797 inches (51\/64)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 0.3125 inches (5\/16)\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\u003eHead Style\u003c\/strong\u003e: Head\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\u003eLock Screw Compatibility\u003c\/strong\u003e: LS-1\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: SF325GK\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51732565131570,"sku":"SF325GK","price":19.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d089b0a7b36c5d4ca8f716b32e5b0d8a_528cd066-7e4a-4534-9e7e-a26a8369f307.jpg?v=1788744501","url":"https:\/\/voomisupply.com\/products\/boneham-sf325gk-slip-fixed-drill-bushing-0-209-in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
