Boneham SF3222GO Slip-fixed Drill Bushing 7/32 in Id Steel

Product Description

The BONEHAM SF3222GO is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. Built to industry code SF, this bushing features a 7/32 inch inside diameter and a 0.5 inch body outside diameter, with a length under head of 1-3/8 inches. Constructed from steel, it provides the wear resistance and dimensional stability required in production drilling environments. The head type design and counterbored body allow it to seat flush or proud depending on fixture plate thickness, making it a dependable choice for repeatable hole location in metalworking and fabrication setups.

This bushing is used in drill jigs and tooling fixtures across machine shops, fabrication facilities, and manufacturing lines. It installs into a mating liner bushing or directly into a tooling plate where slip-fixed retention is specified. The renewable design means the bushing can be replaced without replacing the liner, which is standard practice in high-cycle production fixtures. Compatible with an LS-1 lock screw for positive retention during drilling operations.

Compatibility

Designed for use with LS-1 compatible lock screws in standard SF-style drill jig and fixture applications requiring a slip-fixed, headed, renewable bushing.

Installation Notes

Installation is typically performed by toolmakers or machinists during jig assembly or bushing replacement. The fixture plate and any associated liner bushing should be clean and free of burrs before pressing or inserting the bushing. Ensure the lock screw is properly engaged to prevent rotation or lifting during drilling. Always verify inside diameter clearance is appropriate for the specific cutting tool being guided.
