Boneham SF3222IW Slip-fixed Drill Bushing 0.332 in Id

Product Description

The BONEHAM SF3222IW is a slip-fixed drill bushing designed for use in jig and fixture applications where repeatable hole location accuracy is required. Carrying industry code SF, this bushing features a 0.332 inch inside diameter (letter size Q) with a close tolerance of +0.0001 to +0.0005 inches, a 0.500 inch body outside diameter, and a 1.375 inch length under head. Constructed from steel, it is a renewable, head-style bushing with a counterbored design that accepts an LS-1 compatible lock screw to secure it in the liner bushing during drilling operations. Machinists, tool and die makers, and precision fab shops install these components as part of drill jig setups.

This bushing is suited for production drilling environments where the drill bushing must be removable and replaceable without disturbing the press-fit liner. The slip-fixed design allows the bushing to be inserted and locked in place during use, then removed for tool changes or bushing replacement. It is appropriate for both light and medium-duty drilling, reaming, and boring operations in steel jig plates and fixture bodies. The 1.375 inch length under head provides adequate drill guidance for standard shop depths.

Compatibility

Designed for use with LS-1 compatible lock screws and standard SF-series liner bushings. Fits drill jig plates and fixture bodies requiring a renewable slip-fixed bushing with a 0.500 inch body outside diameter.

Installation Notes

Installation is performed by machinists or toolmakers setting up drill jigs and fixtures. The liner bushing must already be pressed into the jig plate before inserting this slip-fixed bushing. Insert the SF3222IW into the liner and secure with an LS-1 lock screw before beginning drilling operations. Remove the lock screw before attempting to withdraw the bushing to avoid damage to the liner or bushing head.
