Boneham PT286GW Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM PT286GW is a press fit headless drill bushing designed to guide drill bits and other cutting tools with precision in jig and fixture applications. This Industry Code P bushing features a 0.234 inch inside diameter, a 7/16 inch body outside diameter, and a 3/8 inch overall length. Manufactured from steel and hardened to 60 to 65 HRC, it delivers the wear resistance required for repetitive drilling operations. The inside diameter tolerance is held to +0.0001 to +0.0004 inches, ensuring consistent hole location across high-volume production runs. Installation is accomplished by pressing the bushing directly into a prepared drill jig plate.

This bushing is suited for use in drill jigs and production fixtures in metalworking, machining, and fabrication environments. The headless profile sits flush with the jig plate surface, making it appropriate for applications where a protruding head would interfere with workpiece clamping or part clearance. It is a non-renewable style, intended as a permanent press-in component within the jig body. Machinists, tool and die makers, and fixture builders are the primary installers of this type of component.

Key Features

• Press fit installation — no additional fasteners or adhesives required
• Headless design sits flush with jig plate surface for unobstructed workpiece contact
• Steel construction hardened to 60 to 65 HRC for extended wear life
• Inside diameter held to +0.0001 to +0.0004 inches for repeatable hole location accuracy
• Industry Code P designation per ANSI standards
• Non-renewable, permanent-mount configuration

Compatibility

Designed as an ANSI-standard Industry Code P press fit headless drill bushing for use in drill jigs and machining fixtures requiring a 0.234 inch bore and 7/16 inch outside diameter.

Installation Notes

Press fit bushings are installed by tool and die makers or machinists using an arbor press or hydraulic press. The receiving hole in the jig plate must be machined to the correct interference fit tolerance before installation. Once pressed in, this non-renewable bushing is not intended for removal and reinstallation. Follow ANSI jig bushing standards for hole preparation and press-in procedures.
