Constructed from steel, it features a 7\/8 inch (0.8750 inch decimal) inside diameter and a 1-3\/8 inch (1.3750 inch decimal) body outside diameter. The bushing includes a head with a 1-51\/64 inch outside diameter and a 3\/8 inch head height. Length under the head measures 1 inch. Inside diameter tolerance is held to a tight +0.0002 to +0.0006 inches, making this bushing suitable for repeatable, close-tolerance drilling, reaming, or countersinking operations. It is installed by a licensed machinist or tool-and-die technician and used as part of a drill jig assembly.\u003c\/p\u003e\n\u003cp\u003eThis slip-fixed bushing is used in drill jig tooling where a renewable liner bushing is already installed in the jig plate. The SF type slips into the liner and is locked in place with a compatible LS-2 lock screw (sold separately). Typical applications include production drilling, reaming, and boring operations in metalworking shops, aerospace fabrication, and general manufacturing environments. The renewable design allows the bushing to be replaced as it wears, extending the service life of the jig plate assembly without requiring full jig rework.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSF industry code slip-fixed design for use with renewable liner bushings\u003c\/li\u003e\n  \u003cli\u003eSteel construction for wear resistance in repetitive drilling operations\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of +0.0002 to +0.0006 inches for close-tolerance tool guidance\u003c\/li\u003e\n  \u003cli\u003eHead type with 1-51\/64 inch head OD and 3\/8 inch head height for positive seating\u003c\/li\u003e\n  \u003cli\u003eLS-2 compatible lock screw interface for secure retention in the liner\u003c\/li\u003e\n  \u003cli\u003eRenewable bushing design supports long-term jig serviceability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with SF-style renewable liner bushings and LS-2 series lock screws in standard drill jig assemblies conforming to SF bushing industry specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a machinist or tooling technician. Ensure the liner bushing and jig plate bore are clean and free of chips or burrs before inserting the slip-fixed bushing. Secure the bushing with a compatible LS-2 lock screw; do not attempt to press or force the bushing into an undersized liner. Follow applicable shop safety and machine guarding practices whenever the jig is placed in service.\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\u003eInstallation Method\u003c\/strong\u003e: Slip-Fixed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 7\/8 inch (0.8750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: +0.0002 to +0.0006 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 1-3\/8 inch (1.3750 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: 1-51\/64 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 3\/8 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 Bushing\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLock Screw Compatibility\u003c\/strong\u003e: LS-2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCounterbored\u003c\/strong\u003e: No\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: SF8816NW\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51735231562034,"sku":"SF8816NW","price":35.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9f314289c5dc006d7d96bdb0c1c36c06.jpg?v=1788770625","url":"https:\/\/voomisupply.com\/products\/boneham-sf8816nw-slip-fixed-drill-bushing-7-8-in-id-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
