Boneham SF328FP Slip-fixed Drill Bushing 0.182 in Id Steel

Product Description

The BONEHAM SF328FP is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. Classified under industry code SF, this bushing features a 0.182 inch (No. 14 wire gauge) inside diameter with a close-tolerance bore held to +0.0001 to +0.0004 inches for accurate tool guidance. The body outside diameter measures 0.5000 inches with a length under head of 0.5000 inches. Constructed from steel, the SF328FP is a renewable bushing fitted with a head and is compatible with the LS-1 lock screw. It is installed by machinists, toolmakers, and manufacturing technicians working with drill jigs and production fixtures.

This bushing is suited for use in production drilling, reaming, and boring operations where repeatable hole location is required. The slip-fixed design allows the bushing to be inserted and locked in place within a liner bushing using an LS-1 compatible lock screw, making it appropriate for applications that require tool changes between operations or periodic bushing replacement. Typical installations are found in metal fabrication shops, machine shops, and assembly tooling environments handling medium to high production volumes.

Installation Notes

Installation is performed by machinists or toolmakers as part of jig and fixture assembly or maintenance. Ensure the mating liner bushing and jig plate are clean and free of chips before inserting the bushing. The lock screw must be an LS-1 compatible type and should be seated securely to prevent rotation during operation. Always de-energize and lock out any machine before servicing jig components mounted in active fixtures.
