Boneham SFT408JR Slip-fixed Drill Bushing 5/8 in Steel

Product Description

The BONEHAM SFT408JR is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. 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.

This 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.

Installation Notes

Installation is performed by toolmakers or machinists as part of jig and fixture assembly or maintenance. Ensure the liner bushing bore and jig plate are clean and free of chips before seating the bushing. Secure with the appropriate LS-TW-2 lock screw to prevent rotation or lifting during drilling. Always verify inside diameter letter designation matches the intended drill or reamer size before installing.
