Built to ANSI standards, this bushing features a 0.272-inch inside diameter and a 1\/2-inch body outside diameter, with a head outside diameter of 51\/64 inch and a head height of 1\/4 inch. The length under the head measures 3\/8 inch. Constructed from steel and hardened to 60 to 65 HRC, it delivers the wear resistance required for repeatable, high-volume drilling operations. The inside diameter tolerance is held to +0.0001 to +0.0005 inch for consistent tool guidance. It is renewable and accepts an LS-1 compatible lock screw.\u003c\/p\u003e\n\u003cp\u003eThis bushing is used in drill jigs and production fixtures where accurate hole location must be maintained across repeated operations. The slip-fixed design allows the bushing to be installed and locked in a liner bushing, making it suitable for applications requiring tool changes between operations without sacrificing positional accuracy. Machinists, toolmakers, and fixture builders working in metal fabrication, manufacturing, and machine shops are the primary installers of this component.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInside diameter of 0.272 inches held to a tolerance of +0.0001 to +0.0005 inch for precise tool guidance\u003c\/li\u003e\n  \u003cli\u003eBody outside diameter of 0.500 inch with 51\/64-inch head outside diameter\u003c\/li\u003e\n  \u003cli\u003eSteel construction hardened to 60 to 65 HRC for extended service life\u003c\/li\u003e\n  \u003cli\u003eRenewable design allows bushing replacement without disturbing the liner\u003c\/li\u003e\n  \u003cli\u003eLS-1 compatible lock screw retains the bushing securely in the liner bushing\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI standards for interchangeability with other SF-series bushings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ANSI SF-series slip-fixed drill bushing for use in standard liner bushings that accept a 1\/2-inch body outside diameter.

The bushing should be pressed or slipped into a properly sized liner bushing and secured with an LS-1 lock screw. Verify that the liner bushing bore and the fixture plate are clean and free of burrs before seating the bushing. Follow applicable shop safety procedures when working with press-fit or close-tolerance components.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.272 inches (Letter I)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter Tolerance\u003c\/strong\u003e: +0.0001 to +0.0005 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Outside Diameter\u003c\/strong\u003e: 0.500 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 51\/64 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 0.250 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 0.375 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Type\u003c\/strong\u003e: Slip-Fixed (SF)\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\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\u003eStandard\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: SF326HS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51744578568498,"sku":"SF326HS","price":20.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d089b0a7b36c5d4ca8f716b32e5b0d8a_680c97fa-5366-40ba-af86-29579f8269e4.jpg?v=1788858531","url":"https:\/\/voomisupply.com\/products\/boneham-sf326hs-slip-fixed-drill-bushing-0-272-in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
