Boneham P164DY Press Fit Headless Drill Bushing

Product Description

The BONEHAM P164DY is a press fit headless drill bushing designed to guide drill bits and cutting tools with precision in jig and fixture applications. Built to ANSI standards from hardened steel, this bushing delivers consistent bore alignment across repeated drilling operations. It features a 0.1285 inch inside diameter (wire gauge #30), a 1/4 inch outside diameter, and a 1/4 inch overall length. Hardness is rated 60 to 65 HRC, ensuring long service life in production environments. Machinists, toolmakers, and fixture builders are the primary installers of this component.

This bushing is suited for use in drill jigs, machining fixtures, and production tooling setups where accurate hole location is required. The headless design allows for a flush or sub-surface installation, making it appropriate for applications where a headed bushing would interfere with workpiece contact or clamping. It is a non-renewable, permanent-installation style bushing intended for stable, fixed-location drilling operations in shop and production settings.

Key Features

• Press fit installation method for secure, permanent seating in the jig plate
• Headless design allows flush or sub-surface mounting
• 0.1285 inch inside diameter with a close tolerance of +0.0001 to +0.0004 inches for consistent drill guidance
• 60 to 65 HRC hardness provides wear resistance in high-cycle drilling applications
• Meets ANSI standards for drill bushing geometry and dimensional accuracy
• Industry bushing code P for straightforward identification and replacement

Compatibility

Designed as an OEM-style replacement or direct-fit component for drill jigs and machining fixtures requiring a press fit headless bushing with a 0.1285 inch bore and 1/4 inch outside diameter per ANSI P-series specifications.

Installation Notes

Press fit bushings are installed by toolmakers or machinists using an arbor press or similar controlled-force equipment to avoid distortion of the bushing bore. The jig plate bore should be machined to the correct interference fit tolerance before pressing. Ensure the bushing is driven in squarely and fully seated before use. Do not use a hammer blow directly on the bushing face, as this can alter bore geometry.
