Boneham SF2022EL Slip-fixed Drill Bushing 0.147 in Id Steel

Product Description

The BONEHAM SF2022EL is a slip-fixed drill bushing designed for precision tooling and jig applications in metalworking and machining operations. Built to SF industry standards, this bushing features a 0.147 inch inside diameter (wire size 26), a 5/16 inch body outside diameter, and a 1-3/8 inch length under head. Constructed from steel with a hardness rating of 60 to 65 HRC, it delivers the wear resistance and dimensional stability required in high-cycle production drilling environments. The head-style design and counterbored configuration allow secure, repeatable seating in drill jig assemblies.

This bushing is suited for use in fixed and renewable drill jig setups in manufacturing, toolroom, and production machining environments. The slip-fixed design allows the bushing to be installed without rotation, making it appropriate for applications requiring consistent hole location accuracy across repeated operations. It accepts an LS-1 compatible lock screw for positive retention in the jig body. Machinists, tool and die makers, and production technicians typically source this component for jig plate tooling and fixture builds.

Key Features

• SF slip-fixed bushing design per ANSI standards
• 0.147 inch inside diameter with a tight tolerance of +0.0001 to +0.0004 inches for precise drill guidance
• Steel construction hardened to 60 to 65 HRC for extended service life
• Head-style with 35/64 inch head outside diameter and 1/4 inch head height
• Counterbored body for flush or recessed mounting in jig plates
• Renewable bushing design compatible with LS-1 lock screw

Compatibility

Designed as an ANSI-standard SF slip-fixed drill bushing for use in drill jigs requiring LS-1 lock screw retention. Compatible with standard jig plate bores machined to accept 5/16 inch body outside diameter SF-series bushings.

Installation Notes

Installation is typically performed by machinists or tool and die makers using a press or hand driver to seat the bushing flush in the jig plate bore. Always confirm the jig plate bore diameter matches the bushing body outside diameter tolerance before pressing in. Use an LS-1 compatible lock screw to secure the bushing and prevent rotation during drilling operations. Inspect the bushing bore for chips or debris prior to each use to maintain positional accuracy.
