Built to industry code SF, this bushing features a 0.209 inch inside diameter, a 1\/2 inch body outside diameter, and a 3\/4 inch length under head. Constructed from steel, it delivers the hardness and wear resistance required for repetitive drilling operations. The headed design keeps the bushing positively seated in the liner, and the renewable construction means it can be pulled and replaced without disturbing the jig plate. Inside diameter tolerance is held to +0.0001 to +0.0004 inches for consistent hole location.\u003c\/p\u003e\n\u003cp\u003eSlip-fixed bushings in the SF series are standard in production jig plates where a fixed bushing is needed but occasional replacement is anticipated. The SF3212GK suits metalworking, fabrication, and toolroom environments where close-tolerance hole guidance is critical across high-cycle drilling runs. Installation requires a compatible SF liner bushing already pressed into the jig plate. The bushing locks in place using an LS-1 compatible lock screw, securing it against rotation and lifting during the drilling cycle. It is packaged and sold individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSF industry-standard slip-fixed bushing design for use with pressed liner bushings\u003c\/li\u003e\n  \u003cli\u003e0.209 inch inside diameter with a tight tolerance of +0.0001 to +0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch body outside diameter and 3\/4 inch length under head\u003c\/li\u003e\n  \u003cli\u003eSteel construction for hardness and durability in high-cycle drilling applications\u003c\/li\u003e\n  \u003cli\u003eHeaded configuration with 51\/64 inch head outside diameter and 1\/4 inch head height\u003c\/li\u003e\n  \u003cli\u003eRenewable design — removable and replaceable without modifying the jig plate\u003c\/li\u003e\n  \u003cli\u003eCompatible with LS-1 lock screw for positive retention during operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with SF-series liner bushings pressed into jig plates. Locks using an LS-1 compatible lock screw. Not counterbored. Refer to jig plate specifications to confirm liner inside diameter and body fit before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by toolroom machinists or fixture builders using standard hand tools. Confirm the mating liner bushing is fully seated and undamaged before inserting the SF3212GK. Engage the LS-1 lock screw to the correct liner notch position to prevent rotation or lifting under drill thrust. Never force the bushing into a liner with an incompatible bore size, as this will distort the inside diameter and compromise hole location accuracy.\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 Size)\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter (Decimal)\u003c\/strong\u003e: 0.2090 inches\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: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 0.750 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 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Type\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\u003eRenewable\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\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: SF3212GK\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51731570524466,"sku":"SF3212GK","price":22.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aa299f99f9081cd487cb2ebc5663d9d0.jpg?v=1788732627","url":"https:\/\/voomisupply.com\/products\/boneham-sf3212gk-slip-fixed-drill-bushing-0-209-in-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
