Built to ANSI standards, this SF-series bushing features a 23\/64-inch inside diameter, a 3\/4-inch body outside diameter, and a 1-3\/8-inch length under the head. It is manufactured from steel and hardened to 60 to 65 HRC, delivering the wear resistance required for high-cycle drilling operations. The renewable design allows the bushing to be replaced without scrapping the jig plate, making it a practical choice for production environments where tooling sees regular use.\u003c\/p\u003e\n\u003cp\u003eSlip-fixed bushings in the SF series are used in drill jigs, fixture plates, and production tooling setups across metalworking and machining shops. The slip-fit installation method allows the bushing to be inserted or removed from the liner bushing without tools, while the locking screw — compatible with the LS-1 lock screw — secures it in position during operation. This configuration is standard in applications where multiple bushing sizes are needed at the same hole location or where bushings require periodic replacement due to wear.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSlip-fixed installation method for fast bushing changes at the drill jig\u003c\/li\u003e\n  \u003cli\u003e23\/64-inch inside diameter with a close tolerance of +0.0001 to +0.0005 inches for accurate tool guidance\u003c\/li\u003e\n  \u003cli\u003eSteel construction hardened to 60 to 65 HRC for extended service life\u003c\/li\u003e\n  \u003cli\u003eRenewable bushing design reduces jig plate replacement costs\u003c\/li\u003e\n  \u003cli\u003eCompatible with LS-1 lock screw for secure in-position retention\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI standards for drill bushing geometry and tolerancing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ANSI-standard SF-series slip-fixed drill bushing compatible with LS-1 lock screws and standard liner bushings used in drill jig and fixture tooling.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by machinists or toolmakers working with drill jigs and fixture assemblies. Before replacing or installing the bushing, ensure the drilling machine is powered down and the workpiece is fully secured. The LS-1 lock screw must be properly engaged to prevent bushing rotation or withdrawal during drilling. Verify the liner bushing bore is clean and free of chips or burrs before inserting the SF4822JJ.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 23\/64 inches\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: 0.7500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 1-3\/8 inches\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\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\u003eInstallation Method\u003c\/strong\u003e: Slip-Fixed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBushing Industry Code\u003c\/strong\u003e: SF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLock Screw Compatibility\u003c\/strong\u003e: LS-1\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\u003eHead Style\u003c\/strong\u003e: Head\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: SF4822JJ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51752999256370,"sku":"SF4822JJ","price":23.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d089b0a7b36c5d4ca8f716b32e5b0d8a_c37156f7-1874-48e9-8215-e5d5fa4495d3.jpg?v=1788932002","url":"https:\/\/voomisupply.com\/products\/boneham-sf4822jj-slip-fixed-drill-bushing-23-64-in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
