Built to industry code SF, this bushing features a 0.386 inch inside diameter (Letter size W), a 0.750 inch body outside diameter, and a 1 inch length under head. Constructed from steel, it includes a head for positive seating and is renewable, allowing it to be replaced without disturbing the jig plate. Inside diameter tolerance is held to +0.0001 to +0.0005 inches for consistent tool guidance. Lock screw compatibility is LS-1.\u003c\/p\u003e\n\u003cp\u003eThis bushing is used in drill jig applications across metalworking, tooling, and manufacturing environments. The slip-fixed design allows the bushing to be installed and locked in a liner bushing, providing a stable, repeatable guide for production drilling operations. It is well suited for applications where tool changes are infrequent and a secure, non-rotating fit is required. Machinists, tool and die makers, and fixture builders working in job shops or production facilities are the primary installers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSlip-fixed (SF) bushing style for secure, locked installation in liner bushings\u003c\/li\u003e\n  \u003cli\u003e0.386 inch inside diameter with tight tolerance of +0.0001 to +0.0005 inches for accurate tool guidance\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in production machining environments\u003c\/li\u003e\n  \u003cli\u003eRenewable design allows replacement without disturbing the jig plate or liner\u003c\/li\u003e\n  \u003cli\u003eHeaded style provides positive axial location against the jig plate surface\u003c\/li\u003e\n  \u003cli\u003eLS-1 compatible lock screw for secure retention during operation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with LS-1 lock screws and compatible liner bushings accepting a 0.750 inch body outside diameter slip-fixed bushing per SF industry standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by machinists or tooling specialists during jig assembly or bushing replacement. Ensure the liner bushing bore and jig plate surfaces are clean and free of burrs before inserting the slip-fixed bushing. Engage the LS-1 lock screw to prevent rotation or axial movement during cutting operations. Power down all associated machinery before servicing drill jigs or replacing worn bushings.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Style\u003c\/strong\u003e: Slip-Fixed (SF)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.386 inches (Letter Size W)\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: 0.750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1 inch\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\u003eHead Style\u003c\/strong\u003e: Headed\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: SF4816JW\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51748447387954,"sku":"SF4816JW","price":22.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e7ac761303e4e2e3d275704a885be502_77dd99e3-4b31-4afe-9af4-580afd313eb8.jpg?v=1788893889","url":"https:\/\/voomisupply.com\/products\/boneham-sf4816jw-slip-fixed-drill-bushing-0-386-in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
