Boneham PT368IR Press Fit Headless Drill Bushing

Product Description

The BONEHAM PT368IR is a press fit headless drill bushing designed to guide drill bits with precision in jig and fixture applications. Built to Industry Code P standards, this bushing features a 0.323 inch inside diameter, a 9/16 inch body outside diameter, and a 1/2 inch overall length. Constructed from steel, it is pressed directly into a drill jig plate and held in place without a head flange, making it suitable for flush-mount installations where clearance above the plate is required. Machinists and tooling specialists rely on this type of bushing to maintain consistent hole location and extend tool life across production runs.

This bushing is used in drill jig applications across manufacturing, fabrication, and machine shop environments. Its headless design allows it to sit flush or below the jig plate surface, which is useful when workpiece clearance is tight or when the bushing must be recessed. The 0.323 inch ID corresponds to wire gauge and letter drill size P, making it a standard selection for jig plates drilled and reamed to accept press fit bushings of this outside diameter series.

Key Features

• Non-renewable bushing intended for permanent installation

Compatibility

Designed as an OEM-style replacement or new installation press fit headless drill bushing for use in steel drill jig plates machined to accept a 9/16 inch outside diameter press fit bushing of Industry Code P designation.

Installation Notes

Installation is performed by machinists or tooling specialists using an arbor press or hydraulic press to drive the bushing into a reamed jig plate bore. The jig plate bore must be precision-reamed to the correct interference fit diameter before pressing to avoid damage to the bushing or plate. Do not hammer the bushing in directly without a driver to prevent distortion of the inside diameter. This bushing is not designed to be removed and reused once pressed into place.
