Boneham SF4822JB Slip-fixed Drill Bushing 11/32 in Id

Product Description

The BONEHAM SF4822JB is a slip-fixed drill bushing designed for use in jig and fixture applications where a renewable, precision-guided tool interface is required. Built to SF industry code standards, this bushing features an 11/32 inch inside diameter and a 0.75 inch body outside diameter, with a 1-3/8 inch length under the head. Constructed from steel with an inside diameter tolerance of +0.0001 to +0.0005 inches, the SF4822JB delivers consistent bore alignment for drill, reamer, or other rotating tooling passes in production machining environments. The headed design and LS-1 compatible lock screw system allow for secure seating and straightforward removal during tool changes.

This bushing is suited for installation in drill jigs and precision fixtures used in metalworking, fabrication, and toolroom settings. The slip-fixed configuration allows the bushing to be pressed into a liner bushing and locked in place with a lock screw, making it appropriate for operations that require periodic bushing changeover between hole operations or tool types. Machinists, toolmakers, and fixture builders working in industrial production or job-shop environments are the primary installers of this component.

Compatibility

Designed for use with LS-1 series lock screws and compatible liner bushings in standard SF-pattern drill jig fixtures. No additional model-specific compatibility data was provided by the manufacturer for this part number.

Installation Notes

Installation is typically performed by toolmakers or machinists using standard fixture assembly practices. Ensure the mating liner bushing bore and the fixture plate are clean and free of burrs before seating the bushing. Secure the bushing with the appropriate LS-1 lock screw tightened per fixture design requirements. Remove all rotating tooling and de-energize any machine spindle before servicing or replacing bushings in an active fixture.
