Boneham P324GX Press Fit Headless Drill Bushing

Product Description

The BONEHAM P324GX is a press fit headless drill bushing designed to guide drill bits with precision during machining and fabrication operations. Classified under industry code P, this bushing features a 15/64-inch inside diameter and a 1/2-inch outside diameter, with an overall length of 1/4 inch. Constructed from steel, it provides the hardness and wear resistance required for repetitive drilling cycles in production jig and fixture applications. The headless design allows flush or recessed seating in the fixture plate. Installation is permanent — this is not a renewable bushing. Licensed machinists, toolmakers, and precision fabricators are the primary installers of this component.

The P324GX is suited for use in drill jigs and fixture plates where controlled hole location and repeatable drill entry are required. It is appropriate for both light and moderate production environments in metal fabrication, machine shops, and manufacturing facilities. The press fit retention method keeps the bushing securely seated under normal drilling loads without requiring locking hardware. Its compact 1/4-inch length makes it a practical choice for thin fixture plates or applications where overall stack height is a constraint.

Key Features

• Press fit installation method for permanent, secure retention in fixture plates
• 15/64-inch inside diameter with a tight tolerance of +0.0001 to +0.0004 inches for accurate drill guidance
• 1/2-inch body outside diameter and 1/4-inch overall length for compact fitment
• Headless design allows flush or sub-flush seating without protruding above the fixture surface
• Steel construction provides hardness and durability for repetitive drilling operations
• Not counterbored and not renewable — intended as a fixed, long-service installation

Compatibility

Designed as an OEM-style press fit drill bushing for use in standard drill jigs and fixture plates requiring a P-series headless bushing with a 15/64-inch bore and 1/2-inch outside diameter.

Installation Notes

Press fit bushings are installed by toolmakers or precision machinists using an arbor press or hydraulic press to drive the bushing flush into a reamed fixture hole. The receiving hole in the fixture plate must be reamed to the correct interference fit tolerance to ensure proper retention. Do not hammer the bushing directly without a proper press driver to avoid distortion of the bore. Once pressed in, this bushing is not intended for removal or reuse.
