Boneham SF3222EN Slip-fixed Drill Bushing 0.1495 in Id Steel

Product Description

The BONEHAM SF3222EN is a slip-fixed drill bushing built to guide cutting tools with precision in jig and fixture applications. Classified under industry code SF, this bushing features a 0.1495 inch inside diameter (wire size No. 25), a 1/2 inch body outside diameter, and a 1-3/8 inch length under head. Constructed from steel, it is designed for renewable installation, meaning it can be pressed into a liner bushing and removed or replaced without disturbing the fixture. The head type design and counterbored construction allow secure seating, and the part is compatible with LS-1 lock screws for positive retention during machining operations.

Slip-fixed bushings like the SF3222EN are used in production and toolroom environments where drill jigs require repeatable hole location accuracy. The renewable design suits fixtures that see frequent bushing changes due to tool wear or varying drill sizes. This part is installed by machinists, toolmakers, and precision metalworking professionals working with jig plates in light to medium production runs. It is appropriate for use in both horizontal and vertical drill press setups wherever guided drilling, reaming, or boring is required.

Compatibility

Designed as an OEM-style replacement or direct-fit slip-fixed drill bushing for jig fixtures requiring an SF-type renewable bushing with a No. 25 wire size inside diameter and LS-1 lock screw compatibility.

Installation Notes

Installation is performed by toolmakers or machinists using a press fit into a compatible liner bushing already set in the jig plate. Power down and secure all equipment before servicing or replacing bushings in an active fixture. Lock the bushing in place with an LS-1 lock screw after seating to prevent rotation or pull-out during the cut. Inspect the liner bushing for wear before installing a new slip-fixed bushing to ensure proper fit and alignment.
