Boneham P326GE Press Fit Headless Drill Bushing

Product Description

The BONEHAM P326GE is a Type P press fit headless drill bushing designed to guide cutting tools with precision during drilling, reaming, and boring operations. Machined from hardened steel with a surface hardness of 60 to 65 HRC, this bushing resists wear under repeated tooling cycles. It features a 13/64 inch inside diameter, a 1/2 inch body outside diameter, and a 3/8 inch overall length. The headless profile sits flush with the jig plate surface, making it well suited for applications where a protruding head would interfere with workpiece clearance or tooling travel. It is pressed directly into the jig plate without additional fasteners.

This bushing is intended for use in drill jigs and fixture plates in production machining environments. The Type P designation follows ANSI standards for press fit headless bushings, making it a recognized replacement in toolroom and manufacturing settings. Machinists, tool and die makers, and fixture builders install this part when a permanent, non-renewable bushing is required. It is not designed for applications where the bushing needs to be removed and replaced during normal production cycles.

Key Features

• Press fit installation method — no retaining ring or locking mechanism required
• Headless design allows flush mounting in drill jig plates
• Hardened steel construction at 60 to 65 HRC for extended wear life
• Inside diameter tolerance of plus 0.0001 to plus 0.0004 inches for consistent tool guidance
• Conforms to ANSI standards for Type P press fit headless drill bushings
• Non-renewable configuration — intended as a permanent installation

Compatibility

Designed as an ANSI-standard Type P press fit headless drill bushing for use in drill jigs and fixture plates requiring a 1/2 inch OD bore and 13/64 inch tool guidance diameter.

Installation Notes

Installation is performed by toolmakers or machinists using an arbor press or hydraulic press to seat the bushing into a precision-bored jig plate hole. The mating bore in the jig plate must be machined to the appropriate tolerance to achieve proper press fit interference. Ensure the jig plate and bushing are free of debris and burrs before pressing to avoid distortion or misalignment. Because this is a non-renewable bushing, removal typically damages the bushing and may require reboring the jig plate.
