Boneham PT1212CY Press Fit Headless Drill Bushing

Product Description

The BONEHAM PT1212CY is a press fit headless drill bushing designed to guide drill bits with precision in jig and fixture applications. Carrying industry code P, this bushing features a 0.098 inch inside diameter (wire gauge #40) and a 3/16 inch body outside diameter, with an overall length of 3/4 inch. The inside diameter tolerance is held to +0.0001 to +0.0004 inches, providing consistent, repeatable hole placement across production runs. Manufactured from steel, it delivers the hardness and wear resistance required for sustained drilling operations. Machinists, toolmakers, and fixture builders install this type of bushing in drill jigs to maintain hole location accuracy.

This bushing is suited for use in drill jig plates and fixture assemblies in both production shop and maintenance environments. Its headless, press fit design allows it to sit flush within a counterbored hole in the jig body, keeping the working surface clear of obstructions. It is appropriate for light to medium drilling operations where a fixed, non-renewable bushing meets the application requirement. The counterbored configuration is confirmed for this part.

Key Features

• Press fit installation method for secure, permanent seating in jig plates
• Headless design sits flush with the jig surface when installed in a counterbored hole
• Inside diameter of 0.098 inches (wire gauge #40) with a tight tolerance of +0.0001 to +0.0004 inches
• Steel construction provides hardness and wear resistance for drilling operations
• Non-renewable fixed bushing for stable, long-service jig setups
• Counterbored: accommodates flush-mount installation

Compatibility

Designed as an OEM-style replacement or new-installation drill bushing for press fit headless applications conforming to industry code P specifications in standard drill jig fixtures.

Installation Notes

Installation is typically performed by a machinist or toolmaker using an arbor press to drive the bushing flush into a properly sized counterbored hole in the jig plate. The host bore must be machined to the correct interference fit tolerance before pressing to avoid bushing distortion or jig plate damage. Do not hammer the bushing in directly without a driver or press — uneven force can crack the jig plate or skew the bushing. Verify inside diameter clearance with the intended drill size before pressing the bushing permanently into place, as this is a non-renewable design.
