Boneham SFT364IR Slip Fixed Bushing 0.323 in Id Steel

Product Description

The BONEHAM SFT364IR is a slip-fixed drill bushing designed for use in jig and fixture applications where precise hole location and repeatable accuracy are required. This bushing features a 0.323-inch inside diameter, a body outside diameter of 0.5625 inches (9/16 inches), and a length under head of 0.25 inches (1/4 inches). Constructed from steel, it is built to withstand the wear demands of production drilling environments. The head outside diameter measures 0.875 inches (7/8 inches) with a head height of 0.25 inches. This is a renewable bushing, meaning it can be removed and replaced without disturbing the drill jig or fixture liner. Compatible lock screw type is LS-TW-2. Installation is typically performed by toolmakers, fixture builders, and machining professionals.

The SFT364IR slip-fixed bushing is suited for use in drill jigs, machining fixtures, and production tooling setups where consistent hole placement is critical across multiple workpieces. The slip-fixed design allows the bushing to be rotated or removed during a machining sequence without tools, making it appropriate for multi-operation fixtures that require bushing changes between drilling, reaming, or counterboring steps. The inside diameter tolerance of +0.0001 to +0.0005 inches ensures close guidance of the cutting tool. This bushing is classified under industry code SF and carries UNSPSC code 31171603.

Installation Notes

Slip-fixed bushings are installed and removed by toolmakers or machining technicians using the designated lock screw to secure the bushing in the liner during cutting operations. Before servicing or replacing a bushing, ensure the machine spindle is fully stopped and any associated fixtures are safely secured or clamped. Use the correct LS-TW-2 lock screw to prevent the bushing from rotating under load. Verify inside diameter clearance with the intended drill or reamer shank before placing the bushing into production service.
