Built to the SF industry standard, this bushing features a 25\/32-inch inside diameter and a 1-3\/8-inch body outside diameter, with a 1-3\/4-inch length under the head. Manufactured from steel with a hardness rating of 60 to 65 HRC, it delivers the wear resistance required for repeated drilling, reaming, or boring cycles in production environments. A head outside diameter of 1-51\/64 inches and a 3\/8-inch head height provide secure seating against the jig plate surface. This is a renewable bushing, meaning it can be replaced without retooling the liner bushing in the fixture.\u003c\/p\u003e\n\u003cp\u003eThe SF8828NH is used in drill jig assemblies where a slip-in, fixed-position bushing is required. The slip-fixed design allows the bushing to be installed and locked in a liner bushing using an LS-2 compatible lock screw, holding the bushing stationary during the cutting operation. This configuration is standard in high-cycle production jigs found in metalworking, fabrication, and machining shops. It is suitable for applications requiring tight inside-diameter tolerance control, with an ID tolerance of plus 0.0002 to plus 0.0006 inches above nominal.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSF-type slip-fixed design locks in place via LS-2 compatible lock screw for stationary operation during drilling\u003c\/li\u003e\n  \u003cli\u003e25\/32-inch inside diameter with a controlled ID tolerance of plus 0.0002 to plus 0.0006 inches for precision hole guidance\u003c\/li\u003e\n  \u003cli\u003eSteel construction hardened to 60 to 65 HRC for extended wear life in high-cycle jig applications\u003c\/li\u003e\n  \u003cli\u003eRenewable bushing design — replaceable within an existing liner bushing without fixture modification\u003c\/li\u003e\n  \u003cli\u003e1-3\/4-inch length under head provides adequate tool guidance depth for typical production drilling setups\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards for drill bushing geometry and dimensional consistency\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ANSI-standard SF-type slip-fixed renewable drill bushing compatible with LS-2 lock screws and standard SF liner bushings used in drill jig assemblies.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolmakers setting up or maintaining drill jigs and fixtures. The bushing should be inserted into the mating liner bushing and secured with an LS-2 compatible lock screw before commencing any drilling operation. Ensure the fixture and workpiece are properly clamped and the machine is at a complete stop before replacing or repositioning the bushing. Handle hardened bushings carefully to avoid chipping the bore surface during installation or removal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Type\u003c\/strong\u003e: Slip-Fixed (SF)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 25\/32 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: plus 0.0002 to plus 0.0006 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 1.375 inches\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\u003eLength Under Head\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 3\/8 inches\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\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-2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\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: SF8828NH\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51730401493298,"sku":"SF8828NH","price":43.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d089b0a7b36c5d4ca8f716b32e5b0d8a_7b042fb8-cca8-41cc-a6c6-32d265f19697.jpg?v=1788716819","url":"https:\/\/voomisupply.com\/products\/boneham-sf8828nh-slip-fixed-drill-bushing-25-32-in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
