Boneham P204FV Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM P204FV is a press fit headless drill bushing designed to guide cutting tools with precision during drilling, reaming, and boring operations. Manufactured from steel with a hardness of 60 to 65 HRC, this bushing resists wear and maintains accurate tool guidance under repeated use. It features a 0.191 inch inside diameter, a 5/16 inch body outside diameter, and a 1/4 inch overall length. The headless design sits flush with the jig plate surface, making it well-suited for applications where a protruding head would interfere with workpiece clearance or fixture setup. It is installed by press fit, requiring no additional fasteners.

This bushing is intended for use in drill jigs and fixture plates in production machining environments, tool rooms, and precision fabrication shops. The P industry code designation indicates a standardized size within the ANSI drill bushing series, which allows straightforward selection when building or repairing jigs to standard specifications. Machinists and toolmakers install this type of bushing when a permanent, non-renewable press fit solution is required in a fixed jig plate. It is appropriate for moderate- to high-volume drilling setups where bushing replacement is not anticipated during the service life of the fixture.

Key Features

• Press fit installation — no fasteners required, holds securely in the jig plate bore
• Headless design allows flush seating, preventing interference with workpiece or fixture surfaces
• Steel construction hardened to 60 to 65 HRC for extended wear resistance under continuous tool contact
• Inside diameter tolerance of +0.0001 to +0.0004 inches ensures close, repeatable tool guidance
• Conforms to ANSI standards for drill bushing dimensions and fit
• Non-renewable design suited for permanent fixture installations

Compatibility

Designed as an OEM-style replacement or new-build component for ANSI-standard drill jig fixtures requiring a P-series press fit headless bushing with a 0.191 inch inside diameter and 5/16 inch outside diameter.

Installation Notes

Installation is performed by a machinist or toolmaker using a press or arbor press to drive the bushing into a precision-bored jig plate hole sized to achieve the required interference fit. The jig plate bore must be machined to the correct diameter and finish before installation — do not force the bushing into an undersized or improperly finished bore. Once pressed in, this bushing is not intended for removal or replacement. Always verify bushing alignment with the intended drill axis before pressing to final depth.
