Boneham SF206FC Slip-fixed Drill Bushing 0.166 in Id Steel

Product Description

The BONEHAM SF206FC is a slip-fixed drill bushing engineered for precision tooling applications in metalworking and machining operations. Built to SF industry standards per ANSI specifications, this bushing features a 0.166 inch inside diameter (wire size 19), a 5/16 inch body outside diameter, and a 3/8 inch length under the head. Constructed from hardened steel with a Rockwell hardness of 60 to 65 HRC, the SF206FC provides the wear resistance and dimensional consistency required for repeatable hole location in jig and fixture setups. It ships as a renewable bushing with a head configuration and LS-1 compatible lock screw.

This slip-fixed bushing is used in jig boring, drill press, and multi-operation fixture setups where a bushing must be locked in a liner bushing during drilling, reaming, or similar operations. The SF type is a standard industry configuration suited for production environments where tooling components require periodic replacement without disturbing the fixture body. Machinists, tool and die makers, and precision fabricators working in job shops and manufacturing facilities are the primary installers of this component.

Key Features

• 0.166 inch inside diameter with a tight tolerance of +0.0001 to +0.0004 inches for accurate tool guidance
• Hardened steel construction rated 60 to 65 HRC for extended service life under high-cycle conditions
• SF industry code bushing per ANSI standards for interchangeability with standard tooling systems
• Renewable bushing design allows field replacement without removing the liner bushing
• Head-type configuration with 35/64 inch head outside diameter and 1/4 inch head height
• LS-1 compatible lock screw for positive retention during machining operations

Compatibility

Designed as an ANSI-standard SF-type slip-fixed drill bushing compatible with LS-1 lock screws and standard liner bushings used in jig and fixture tooling systems.

Installation Notes

Installation is performed by tool and die makers or machinists as part of jig and fixture assembly or maintenance. The bushing slides into a liner bushing already pressed into the fixture plate and is secured with an LS-1 lock screw to prevent rotation during tool operation. Ensure the liner bushing bore and the SF206FC body are free of burrs and debris before installation. Always disengage the machine spindle and secure the workpiece fixture before removing or installing drill bushings.
