Boneham PT1210BW Press Fit Headless Drill Bushing

Product Description

The BONEHAM PT1210BW 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 0.067 inch inside diameter (wire gauge size number 51) and a 3/16 inch body outside diameter, with an overall length of 5/8 inch. Manufactured from steel hardened to 60 to 65 HRC, it delivers the wear resistance required for repetitive drilling operations in production environments. The headless profile allows flush or sub-flush seating in the jig plate without a protruding flange. Installation is achieved by pressing the bushing directly into the fixture plate bore with no locking collar or liner bushing required.

This bushing is suited for use in drill jigs, fixtures, and precision tooling setups found in metalworking, machining, and fabrication shops. The press fit design makes it appropriate for permanent installations where the bushing will not need routine removal or replacement during production runs. Machinists, tool and die makers, and fixture builders are the typical end users. It is appropriate for both light-duty prototyping fixtures and higher-volume production jigs where consistent hole location is critical.

Key Features

• Press fit installation — no liner bushing or locking collar required
• Headless design seats flush with the jig plate surface
• Steel construction hardened to 60 to 65 HRC for extended wear life
• Inside diameter tolerance of +0.0001 to +0.0004 inches for accurate drill guidance
• Conforms to ANSI standards for drill bushing geometry and dimensioning
• Industry code P for straightforward cross-reference and replacement sourcing

Compatibility

Designed as a permanent press fit replacement or new-installation bushing for drill jigs and fixtures requiring a headless style bushing with a 0.067 inch bore and 3/16 inch outside diameter, conforming to ANSI P-series drill bushing standards.

Installation Notes

Press fit bushings are installed by a toolmaker or machinist using an arbor press or similar controlled force equipment — never drive them with an unguided hammer, as this can crack the bushing or damage the bore. The receiving bore in the jig plate should be sized to the recommended interference fit for the bushing outside diameter before installation. Once pressed in, these bushings are not intended for removal and reinstallation. Always de-energize and lock out any associated machine before performing fixture maintenance or bushing replacement.
