Boneham P204EU Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM P204EU is a press fit headless drill bushing designed to guide drill bits and other cutting tools with precision in jig and fixture applications. Manufactured from steel with a hardness of 60 to 65 HRC, this bushing resists wear and maintains dimensional accuracy over repeated use. The headless design sits flush within the jig plate, making it well suited for applications where a protruding head would interfere with workpiece clearance or tool travel. With a 5/32-inch inside diameter and a 5/16-inch outside diameter, this bushing conforms to ANSI standards and meets the dimensional requirements of the industry P bushing code.

This bushing is used in metalworking, machining, and manufacturing environments where accurate hole location is critical. It is pressed directly into a jig plate or fixture body without a retaining head, making it appropriate for flush-mount installations on production tooling, drill jigs, and transfer fixtures. The 1/4-inch overall bushing length suits thin jig plates and compact fixture designs. Machinists, tool and die makers, and fixture builders are the primary installers of this component.

Key Features

• Headless press fit design for flush installation in jig plates and fixtures
• Steel construction hardened to 60 to 65 HRC for extended wear life
• 5/32-inch inside diameter with a tolerance of +0.0001 to +0.0004 inches for precise tool guidance
• 5/16-inch body outside diameter and 1/4-inch overall length
• Conforms to ANSI standards and P bushing industry code
• Non-renewable design intended for permanent press fit installation

Compatibility

Designed as an OEM-style replacement or direct-fit component for jigs and fixtures requiring an ANSI P-code press fit headless drill bushing with a 5/32-inch inside diameter and 5/16-inch outside diameter.

Installation Notes

Installation is performed by machinists or tool and die makers using an arbor press or hydraulic press to seat the bushing into a properly sized jig plate bore. The receiving bore should be machined to the appropriate interference fit tolerance to ensure secure retention without distorting the bushing ID. Do not drive the bushing in with a hammer directly against the bore face, as this can damage the bushing or misalign it within the plate. Once pressed in, this bushing is not intended for removal or reuse.
