Boneham SF206EZ Slip-fixed Drill Bushing 0.161 in Id Steel

Product Description

The BONEHAM SF206EZ is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. Built to the SF industry code, it features a 0.161-inch inside diameter (wire size 20), a 5/16-inch body outside diameter, and a 3/8-inch length under the head. Constructed from steel hardened to 60 to 65 HRC, the SF206EZ maintains tight inside diameter tolerances of +0.0001 to +0.0004 inches for repeatable, accurate hole location across production runs. It is compatible with the LS-1 lock screw and is renewable, making it suitable for high-cycle tooling setups where bushing replacement is routine.

This bushing is used in drill jigs, fixture plates, and production tooling where guided drilling, reaming, or boring operations require consistent hole positioning. The headed design seats against the jig plate surface, and the slip-fixed style allows the bushing to be removed and replaced without disturbing the liner bushing in the plate. It is well-suited for metalworking and machining environments, including both job shop and production floor applications. Machinists, tool-and-die makers, and fixture builders are the primary installers.

Key Features

• SF industry code slip-fixed bushing — removable and renewable in the field
• 0.161-inch inside diameter with +0.0001 to +0.0004-inch tolerance for precise tool guidance
• Steel construction hardened to 60 to 65 HRC for wear resistance in high-cycle applications
• Headed design with 35/64-inch head outside diameter and 1/4-inch head height
• Compatible with LS-1 lock screw for positive retention in the liner bushing
• Meets ANSI standards for drill bushing dimensions and tolerances

Compatibility

Designed as an ANSI-standard SF-type slip-fixed drill bushing compatible with LS-1 lock screws and standard liner bushings accepting a 5/16-inch body outside diameter.

Installation Notes

Installation is performed by machinists or toolmakers during jig setup or bushing replacement. Power down and secure any machine before servicing a drill jig or fixture. The slip-fixed bushing rotates into the liner bushing and is locked in position with an LS-1 lock screw — confirm the lock screw is fully engaged before use. Inspect the liner bushing bore for wear before installing a new slip-fixed bushing to ensure proper seating and tool guidance.
