Boneham SF8822NU Slip-fixed Drill Bushing 55/64 in Id Steel

Product Description

The BONEHAM SF8822NU is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. Built to industry code SF, this bushing features a 55/64-inch inside diameter and a 1-3/8-inch body outside diameter, with a 1-3/8-inch length under the head. The head outside diameter measures 1-51/64 inches with a 3/8-inch head height. Constructed from steel, it provides durable wear resistance in high-cycle drilling operations. The slip-fixed design allows the bushing to be installed and removed without tools, making it well suited for operations requiring frequent bushing changes between drill and reamer sizes.

This bushing is used in drill jig assemblies across metalworking, tooling, and machining environments. It is installed in a liner bushing that is permanently pressed into the jig plate, allowing the SF bushing to slip in and seat with a locking screw. Typical applications include production drilling, reaming, and counterboring operations where consistent hole location and tool alignment are critical. It is compatible with an LS-2 lock screw, which retains the bushing during the cutting operation and releases it for removal when the operation changes.

Compatibility

Designed for use with an LS-2 compatible lock screw and intended to seat within a standard SF-series liner bushing pressed into a drill jig plate.

Installation Notes

Installation and removal of slip-fixed bushings is typically performed by tool and die makers or machining setup technicians. The mating liner bushing must already be permanently installed in the jig plate before seating this bushing. Ensure the work piece is secured and the machine is at a full stop before inserting or removing the bushing. Lock the bushing in place with an LS-2 lock screw before beginning any cutting operation.
