Boneham SF4822LA Slip-fixed Drill Bushing 15/32 in Id Steel

Product Description

The BONEHAM SF4822LA is a slip-fixed drill bushing designed to guide cutting tools with precision during machining and fabrication operations. Built to industry code SF, this bushing features a 15/32 inch inside diameter, a 0.75 inch body outside diameter, and a 1-3/8 inch length under head. Constructed from steel, it provides the rigidity and wear resistance required for repetitive drilling, reaming, or boring tasks on production fixtures and jig plates. A headed design and renewable construction make it straightforward to replace without retooling the entire fixture. The inside diameter tolerance of +0.0001 to +0.0005 inches ensures consistent tool guidance across high-volume runs.

This bushing is suited for use in drill jigs, fixture plates, and tooling setups found in metalworking, general fabrication, and precision machining environments. It is typically installed by machinists, toolmakers, and fixture builders working in job shops or production facilities. The slip-fixed installation method allows the bushing to be seated and locked in place using a compatible lock screw, providing a stable, repeatable guide point without permanent press-fit installation. It accepts an LS-1 compatible lock screw for retention.

Key Features

• Slip-fixed installation method — no press fit required, serviceable and replaceable in the field
• 15/32 inch inside diameter with a tight tolerance of +0.0001 to +0.0005 inches for accurate tool guidance
• Steel construction for high wear resistance and rigidity under repeated drilling cycles
• Headed design with 1-3/64 inch head outside diameter and 1/4 inch head height for positive seating on jig plates
• Renewable bushing design — can be swapped out independently to extend fixture service life
• LS-1 compatible lock screw interface for secure retention during operation

Compatibility

Designed for use with LS-1 compatible lock screws. Fits standard drill jig fixtures and tooling plates sized to accept a 3/4 inch body outside diameter SF-style slip-fixed bushing.

Installation Notes

Installation is typically performed by machinists or toolmakers. Ensure the liner bushing or jig plate bore is clean and free of burrs before inserting the bushing. Lock the bushing in place using a compatible LS-1 lock screw — do not overtighten, as this can distort the bushing bore. Verify inside diameter alignment with the tool path before beginning any drilling operation.
