Boneham SFT244GB Slip-fixed Drill Bushing 0.199 in Id Steel

Product Description

The BONEHAM SFT244GB is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. Classified under industry code SF, this head-type bushing features an inside diameter of 0.199 inches and a body outside diameter of 0.375 inches. The head outside diameter measures 0.625 inches, and the length under head is 0.25 inches. Constructed from steel, the SFT244GB provides durable, renewable service in production drilling operations where repeatable hole location accuracy is critical. It is compatible with the LS-TW-2 lock screw for secure seating in the liner bushing.

This bushing is used in drill jigs and machining fixtures across manufacturing, toolmaking, and general metalworking environments. The slip-fixed design allows the bushing to be installed and locked in place via a compatible lock screw, making it suitable for applications where the bushing remains stationary during the drilling cycle. The renewable construction means the bushing can be replaced without disturbing the jig body, reducing downtime in high-cycle production setups. Machinists, toolmakers, and fixture builders are the primary installers of this component.

Installation Notes

Installation is performed by machinists or toolmakers using standard fixture assembly practices. Before installing or replacing the bushing, ensure the machine is fully de-energized and the workpiece is secured. The lock screw should be engaged after the bushing is seated flush in the liner to prevent rotation or axial movement during tool operation. Follow applicable shop safety and tooling manufacturer guidelines when servicing jig components.
