Boneham SFT365IU Slip-fixed Drill Bushing 21/64 in Steel

Product Description

The BONEHAM SFT365IU is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. It features a 21/64-inch inside diameter and a 9/16-inch body outside diameter, with a 5/16-inch length under the head and a 7/8-inch head outside diameter. Manufactured from steel, this bushing accepts a press-fit installation method with a slip-fixed configuration that allows tool removal while retaining the liner bushing. The renewable design means the bushing can be replaced without disturbing the jig plate, making it a practical choice for production drilling operations.

This bushing is intended for use in drill jigs, fixtures, and tooling plates where repeatable hole location is required. The head-type configuration seats against the jig plate surface to control drilling depth and lateral movement. It is compatible with the LS-TW-2 lock screw, which secures the bushing during operation. Typical installers include toolmakers, machinist tradespeople, and fixture builders working in manufacturing, fabrication, and maintenance environments.

Compatibility

Designed for use with LS-TW-2 compatible lock screws. Fits standard drill jig plates and fixture assemblies requiring an SF-series slip-fixed bushing with a 9/16-inch body outside diameter.

Installation Notes

Installation is typically performed by toolmakers or machinists using standard press or hand-drive methods appropriate for slip-fixed bushings. Ensure the liner bushing and jig plate bore are clean and free of burrs before seating. Confirm lock screw engagement with the LS-TW-2 screw before use. Never force the bushing with impact tools that could deform the head or alter the inside diameter tolerance.
