Boneham SF3222FF Slip-fixed Drill Bushing 0.1695 in Id

Product Description

The BONEHAM SF3222FF is a slip-fixed drill bushing manufactured from steel, designed to guide cutting tools with precision in jig and fixture applications. Classified under industry code SF, this renewable bushing features an inside diameter of 0.1695 inches (wire size 18) with a tight inside diameter tolerance of +0.0001 to +0.0004 inches, ensuring accurate hole location and repeatable tool guidance. The body outside diameter measures 0.5 inches, and the length under head is 1-3/8 inches. The bushing is counterbored and includes a head with an outside diameter of 51/64 inches and a head height of 1/4 inch. It is compatible with the LS-1 lock screw for secure seating in the liner bushing.

This slip-fixed bushing is used in precision machining environments where drill jigs and fixtures require repeatable, accurate tool guidance. The slip-fixed design allows the bushing to be installed over a press-fit liner bushing and locked in place during the drilling operation. It is well suited for production drilling, reaming, and similar operations in both manual and CNC-assisted fixturing setups. Machinists, tool and die makers, and fixture builders are the primary installers of this component.

Installation Notes

Installation is performed by machinists or tool and die professionals working with drill jig fixtures. Before replacing or installing a slip-fixed bushing, ensure the machine is powered down and all cutting tools are clear of the work area. The SF bushing slips into the installed liner bushing and is secured with an LS-1 lock screw — confirm the lock screw is fully engaged before beginning any drilling operation. Do not force the bushing into a liner that does not match the body outside diameter.
