Boneham SF3222FV Slip-fixed Drill Bushing 0.191 in Id

Product Description

The BONEHAM SF3222FV is a slip-fixed drill bushing designed for use in jig plates and fixture tooling applications where repeatable, accurate hole guidance is required. Built to industry code SF, this bushing features an inside diameter of 0.191 inches (wire size No. 11) and a body outside diameter of 0.500 inches. The length under head measures 1-3/8 inches. Constructed from steel, it includes a head for positive seating in a counterbored jig plate and is compatible with the LS-1 lock screw for secure retention during drilling operations. This is a renewable bushing, meaning it can be removed and replaced without disturbing the liner bushing in the fixture.

Slip-fixed bushings of this type are used in production drilling fixtures, welding fixtures, and machining jigs where a specific drill or reamer size must be guided precisely and consistently. The SF design allows the bushing to be locked in place via a set screw during the operation, then removed and swapped for a different size or type when the operation changes. This makes them well suited for multi-operation tooling setups in machine shops, tool rooms, and manufacturing environments. The counterbored head seating ensures flush or recessed installation in the fixture plate.

Compatibility

Designed for use with LS-1 series lock screws and standard liner bushings that accept SF industry-code slip-fixed bushings. Consult your fixture design specifications to confirm liner bushing bore size before installation.

Installation Notes

Installation is performed by machinists or toolmakers during fixture assembly or maintenance. The bushing is inserted into a compatible liner bushing already pressed into the jig plate, then secured with an LS-1 lock screw. Ensure the liner bushing bore and the slip-fixed bushing outside diameter are clean and free of chips or burrs before insertion. When removing or replacing the bushing, disengage the lock screw fully to avoid damage to the bushing head or liner.
