Boneham SF328FG Slip-fixed Drill Bushing 11/64 in Id

Product Description

The BONEHAM SF328FG is a slip-fixed drill bushing designed for precision tooling and jig applications in metal fabrication and machining operations. Built to ANSI standards, this bushing features an inside diameter of 11/64 inches with a tight tolerance of +0.0001 to +0.0004 inches, ensuring accurate drill guidance and repeatable hole location. The body outside diameter measures 0.5 inches with a 1/2-inch length under the head. Constructed from steel with a hardness rating of 60 to 65 HRC, the SF328FG delivers the wear resistance required for production drilling environments. It installs via a slip-fixed method and is renewable, making it a practical choice for drill jig maintenance and toolroom work.

This bushing fits drill jig applications requiring SF-series components per ANSI bushing standards. The head-type design with a 51/64-inch head outside diameter and 1/4-inch head height provides positive seating against the jig plate. The SF328FG is compatible with LS-1 lock screws, which secure the bushing in the jig liner during drilling operations. Typical users include tool-and-die makers, machinist shops, and precision fabrication facilities that rely on standardized jig bushing systems for consistent hole placement across production runs.

Key Features

• Slip-fixed installation method with renewable bushing design for easy field replacement
• Inside diameter tolerance of +0.0001 to +0.0004 inches for precision drill guidance
• Steel construction hardened to 60 to 65 HRC for long service life in production drilling
• Head type with 51/64-inch head OD and 1/4-inch head height for positive jig plate seating
• LS-1 lock screw compatible for secure retention in jig liner
• Meets ANSI standards for SF-series drill bushings

Compatibility

Designed as an ANSI SF-series slip-fixed drill bushing compatible with standard jig liners and LS-1 lock screws. Verify inside diameter, body OD, and length under head against existing jig specifications before installation.

Installation Notes

Installation is performed by qualified toolroom machinists or tool-and-die technicians. The slip-fixed bushing slides into a mating jig liner and is secured with an LS-1 lock screw to prevent rotation during drilling. Ensure the jig plate and liner are clean and free of chips before seating the bushing. Because the bushing is renewable, worn components can be swapped without replacing the full jig assembly.
