Boneham SFT406JR Slip-fixed Drill Bushing 5/8 in Steel

Product Description

The BONEHAM SFT406JR is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. Assigned industry code SF, this bushing features a 0.625 inch body outside diameter, a 3/8 inch length under the head, and is manufactured from steel for durability in production drilling environments. The head outside diameter measures 7/8 inch with a 1/4 inch head height. The inside diameter tolerance is held to a tight plus 0.0001 to plus 0.0005 inch range, making it suitable for close-tolerance work. This part is installed and serviced by toolmakers, machinists, and maintenance technicians working with drill jigs.

The SFT406JR is used in jig plate applications where a bushing must be removed and replaced during production runs. The slip-fixed design allows the bushing to seat securely in a liner bushing while still being removable with the appropriate tool. It accepts an inside diameter designated by letter V and is compatible with LS-TW-2 lock screws for positive retention during drilling operations. It is a renewable bushing, meaning it can be replaced independently of the liner without disturbing the jig plate itself.

Key Features

• Slip-fixed (SF) installation method for removable-bushing jig applications
• Body outside diameter of 0.625 inches for precise liner fit
• Inside diameter tolerance of plus 0.0001 to plus 0.0005 inch for close-tolerance tool guidance
• Steel construction for wear resistance in production drilling environments
• Compatible with LS-TW-2 lock screws for secure seating
• Renewable design allows independent replacement without disturbing the jig plate

Compatibility

Designed for use with LS-TW-2 compatible lock screws and standard liner bushings accepting a 0.625 inch body outside diameter. Renewable slip-fixed design is compatible with standard drill jig plates using the SF industry bushing system.

Installation Notes

Installation is typically performed by toolmakers or machinists during jig setup or bushing replacement. Power down all associated machinery and secure the jig before removing or installing bushings. Use the correct removal tool for slip-fixed bushings to avoid damaging the liner or head. Confirm lock screw engagement after seating the bushing to prevent rotation or pullout during drilling operations.
