Boneham SF2016CB Slip-fixed Drill Bushing 0.073 in Id Steel

Product Description

The BONEHAM SF2016CB is a slip-fixed drill bushing designed to guide cutting tools with precision in jig and fixture applications. It features an inside diameter of 0.073 inches (wire size No. 49) with a tight tolerance of +0.0001 to +0.0004 inches, a body outside diameter of 0.3125 inches (5/16 inch), and a length under head of 1 inch. Constructed from steel, this bushing includes a head and is counterbored for use with an LS-1 compatible lock screw. It is a renewable bushing, meaning it can be removed and replaced within a liner bushing without disturbing the jig plate. Machinists, toolmakers, and fixture builders install this type of component in precision drilling operations.

This bushing is suited for use in drill jigs, fixture plates, and tooling setups where repeatable hole location is critical. The slip-fixed style allows the bushing to be held in position with a lock screw once installed in a liner bushing, making it appropriate for single-operation drilling or applications where the bushing remains stationary during the cut. Its steel construction handles the wear demands of production drilling in both job shop and manufacturing environments.

Compatibility

Designed for use with LS-1 compatible lock screws and standard liner bushings that accept SF-style renewable drill bushings.

Installation Notes

Slip-fixed drill bushings are installed by toolmakers or machinists into a pressed liner bushing already seated in the jig plate. Ensure the liner bushing bore and the jig plate are clean and free of chips before inserting the bushing. Secure the bushing with the appropriate LS-1 lock screw to prevent rotation or axial movement during drilling. Follow applicable fixture design standards and shop safety procedures when setting up jig tooling.
