Built to ANSI standards, it features a 21\/64 inch inside diameter with a tight tolerance of +0.0001 to +0.0005 inches, a 9\/16 inch body outside diameter, and a 3\/8 inch length under the head. Manufactured from steel hardened to 60-65 HRC, this bushing delivers consistent bore guidance and extended service life in production drilling, reaming, and similar operations. Installation and removal require no press fit, making tool changes efficient in high-volume or multi-operation fixtures. A lock screw compatible with the LS-TW-2 fastener secures the bushing in the liner during use.\u003c\/p\u003e\u003cp\u003eThis bushing is suited for use in drill jigs, modular fixturing systems, and production tooling setups found in machining, metalworking, and manufacturing environments. The slip-fixed design allows the bushing to be replaced without disturbing the press-fit liner bushing installed in the jig plate, reducing downtime when switching between operations or replacing worn bushings. It is a standard choice for tooling engineers and machinist trade professionals setting up multi-hole or multi-operation jig assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSlip-fixed installation method allows removal and replacement without disturbing the liner bushing\u003c\/li\u003e\n\u003cli\u003eInside diameter tolerance of +0.0001 to +0.0005 inches for precise tool guidance\u003c\/li\u003e\n\u003cli\u003eSteel construction hardened to 60-65 HRC for wear resistance in repetitive drilling operations\u003c\/li\u003e\n\u003cli\u003eHeaded design with 7\/8 inch head outside diameter and 1\/4 inch head height for positive seating in liner\u003c\/li\u003e\n\u003cli\u003eCompatible with LS-TW-2 lock screw for secure retention during machining\u003c\/li\u003e\n\u003cli\u003eMeets ANSI standards for renewable drill bushings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with LS-TW-2 compatible lock screws and standard ANSI liner bushings in drill jig and fixture applications.

The bushing slips into a press-fit liner already installed in the jig plate and is locked in place using an LS-TW-2 lock screw. Ensure the liner bore and bushing body are free of chips and debris before seating. Always de-energize machine tools and secure the fixture before servicing bushings in production jigs.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 21\/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: 9\/16 inches (0.5625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Under Head\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Outside Diameter\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Height\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Configuration\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\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-TW-2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.37 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: SFT366IU\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BONEHAM","offers":[{"title":"Default Title","offer_id":51730428756274,"sku":"SFT366IU","price":20.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d089b0a7b36c5d4ca8f716b32e5b0d8a_cbddddf9-3120-4313-9607-0a26b4b541ad.jpg?v=1788717291","url":"https:\/\/voomisupply.com\/products\/boneham-sft366iu-slip-fixed-drill-bushing-21-64-in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
