Manufactured from steel, this SF-series bushing features a 5\/8 inch body outside diameter and a 1\/2 inch length under head. The headed design seats firmly against the jig plate, while the slip-fixed installation method allows the bushing to be installed and removed without permanent press-fitting. Inside diameter tolerance is held to +0.0001 to +0.0005 inches, supporting accurate, repeatable hole location in production drilling operations. Lock screw compatibility with the LS-TW-2 screw keeps the bushing secured during use.\u003c\/p\u003e\n\u003cp\u003eThis bushing is suited for metalworking, machining, and fabrication environments where renewable tooling bushings are required. The SF industry code identifies it as a slip-fixed type, making it appropriate for jig setups where the bushing must be swapped out for different drill sizes or replaced after wear. The renewable design reduces downtime by allowing bushing replacement without disturbing the liner bushing or jig plate. Machinists, toolmakers, and fixture builders working in job shops or production facilities are the primary installers of this component.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSlip-fixed installation method for tool-free removal and replacement\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in repetitive drilling applications\u003c\/li\u003e\n  \u003cli\u003eInside diameter tolerance of +0.0001 to +0.0005 inches for precise tool guidance\u003c\/li\u003e\n  \u003cli\u003eHeaded design with 7\/8 inch head OD and 1\/4 inch head height for positive seating\u003c\/li\u003e\n  \u003cli\u003eCompatible with LS-TW-2 lock screw to prevent rotation during operation\u003c\/li\u003e\n  \u003cli\u003eRenewable bushing design extends jig plate service life\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with LS-TW-2 lock screws.
