Boneham SFT2816HS Slip-fixed Drill Bushing 0.272 in Id Steel

Product Description

The BONEHAM SFT2816HS is a slip-fixed drill bushing designed to guide cutting tools with precision during drilling, reaming, and boring operations. Built to industry code SF, this headed bushing features a 0.272 inch inside diameter, a 7/16 inch body outside diameter, and a 1 inch length under head. The steel construction provides the durability required for repeated use in production jigs and fixtures. It is a renewable bushing, meaning it can be replaced without replacing the jig plate, and is compatible with the LS-TW-2 lock screw for secure retention during operation. Machinists and tool-and-die professionals install this type of bushing in drill jig assemblies.

This bushing is suited for use in drill jig tooling in both production machining and maintenance environments. The slip-fixed design allows the bushing to be installed and locked in place within a liner bushing, making it appropriate for applications where multiple operations are performed at a single hole location. The 5/8 inch head outside diameter and 1/4 inch head height provide positive seating against the jig plate surface, helping maintain consistent tool alignment across repeated cycles.

Key Features

• Slip-fixed installation method for use with liner bushings in drill jig assemblies
• Renewable bushing design allows field replacement without disturbing the jig plate
• Inside diameter tolerance of plus 0.0001 to plus 0.0005 inches for precise tool guidance
• Compatible with LS-TW-2 lock screw for secure locking during operation
• Headed design with 5/8 inch head OD and 1/4 inch head height for positive plate seating
• Steel construction for long service life in production and maintenance jig applications

Compatibility

Compatible with LS-TW-2 lock screws. Designed as an OEM-style renewable slip-fixed bushing for use with standard liner bushings in drill jig tooling conforming to industry code SF.

Installation Notes

Installation is performed by machinists or tool-and-die technicians. The bushing is inserted into a mating liner bushing already pressed into the jig plate, then rotated and locked with an LS-TW-2 lock screw. Ensure the jig assembly is secured and the workpiece is properly clamped before tool engagement. Do not force the bushing into an undersized liner; verify liner inside diameter compatibility before installation.
