Boneham SF328HX Slip-fixed Drill Bushing 9/32 in Id Steel

Product Description

The BONEHAM SF328HX is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. Built to the SF industry code under ANSI standards, this bushing features a 9/32 inch inside diameter and a 0.5000 inch body outside diameter, with an inside diameter tolerance of +0.0001 to +0.0005 inches for tight, repeatable tool guidance. The head-style design includes a 51/64 inch head outside diameter and a 1/4 inch head height. Hardness runs 60 to 65 HRC throughout, making it well-suited for high-cycle production environments. Machinists, tool and die makers, and fixture builders are the primary installers.

This bushing is used in drill jigs and machining fixtures where a removable, renewable bushing is required. The slip-fixed configuration allows the bushing to be seated and locked without press-fitting, making it practical for applications that require periodic bushing replacement during a production run. The 1/2 inch length under head suits standard jig plate thicknesses commonly encountered in manufacturing and metalworking operations. It is compatible with an LS-1 lock screw for positive retention during use.

Key Features

• SF industry code slip-fixed installation method for tool-free removal and replacement
• 9/32 inch inside diameter with +0.0001 to +0.0005 inch tolerance for precise tool guidance
• 60 to 65 HRC hardness for extended wear life in high-cycle drilling applications
• Head-style design with 51/64 inch head OD and 1/4 inch head height for positive seating against jig plate
• Renewable bushing construction reduces fixture downtime during production
• LS-1 lock screw compatible for secure retention during operation

Compatibility

Compatible with LS-1 lock screws. Designed as an ANSI-standard SF-type slip-fixed renewable drill bushing for use in standard drill jigs and machining fixtures that accept head-style SF bushings.

Installation Notes

Installation is performed by machinists or tool and die technicians. Ensure the jig plate bore is clean and dimensionally correct for the 0.5000 inch body OD before seating the bushing. Power down and lock out all machine spindles before servicing fixtures or replacing bushings. Secure with an LS-1 compatible lock screw to prevent rotation or axial movement during drilling operations.
