Boneham SF488KG Slip-fixed Drill Bushing 13/32 Id 3/4 Od

Product Description

The BONEHAM SF488KG is a slip-fixed drill bushing designed for precision locating and guiding of cutting tools in jig and fixture applications. Built to the SF industry code, this bushing features a 13/32 inch inside diameter and a 3/4 inch body outside diameter with a 1/2 inch length under the head. Constructed from steel hardened to 60 to 65 HRC, it delivers the wear resistance required in production drilling environments. The headed design seats securely in a counterbored jig plate, and the inside diameter tolerance of +0.0001 to +0.0005 inches ensures accurate tool guidance across repeated operations.

This bushing is used in drill jigs and fixture plates wherever a renewable, slip-fit locating bushing is needed. The slip-fixed style allows the bushing to be installed and locked in place using an LS-1 compatible lock screw, preventing rotation during cutting operations. Typical applications include production machining shops, tool rooms, and precision fabrication environments where repeatable hole location is critical. It is suitable for use with standard drill press and CNC drilling setups requiring guided tool entry.

Key Features

• SF industry code slip-fixed configuration with headed design for positive seating in counterbored fixture plates
• Steel construction hardened to 60 to 65 HRC for long service life in high-cycle drilling applications
• Inside diameter tolerance of +0.0001 to +0.0005 inches for consistent tool guidance
• LS-1 compatible lock screw interface prevents bushing rotation during operation
• Renewable bushing design allows field replacement without scrapping the jig plate
• 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. Fits standard jig plates counterbored to accept a 3/4 inch body outside diameter slip-fixed bushing.

Installation Notes

Installation is typically performed by machinists or tool and die makers during jig and fixture assembly or maintenance. Ensure the jig plate counterbore is clean and free of chips or burrs before pressing the bushing into place. An LS-1 compatible lock screw must be used to secure the bushing against rotation during cutting operations. Do not exceed the hardness rating of mating fixture components when specifying press or slip fit interfaces.
