Boneham PT6410NC Press Fit Headless Drill Bushing

Product Description

The BONEHAM PT6410NC is a press fit headless drill bushing designed to guide cutting tools with precision in jig and fixture applications. It features a 0.75 inch inside diameter, a 1 inch body outside diameter, and an overall length of 0.625 inches. Manufactured from hardened steel with a hardness rating of 60 to 65 HRC, this bushing provides reliable wear resistance under repeated drilling cycles. It installs without fasteners or a head flange, seating directly into a prepared hole in the jig plate. Machinists and tooling engineers working in production or job-shop environments rely on this type of bushing to maintain hole location accuracy across high-volume runs.

This bushing is suited for use in drill jigs, fixture plates, and tooling setups where headless press fit installation is required. The headless design keeps the bushing flush with or below the jig plate surface, making it appropriate for close-clearance applications. It conforms to ANSI standards for drill bushings and carries the industry code P, which designates its dimensional series. Typical applications include production drilling operations in metalworking, aerospace component fabrication, and general machining environments where repeatable hole placement is critical.

Key Features

• Press fit installation — no fasteners or locking collar required
• Headless design sits flush with or below the jig plate surface
• Hardened steel construction, 60 to 65 HRC for extended wear life
• Inside diameter tolerance of +0.0001 to +0.0005 inches for close tool guidance
• Conforms to ANSI drill bushing standards, industry code P
• Non-renewable design — intended for permanent press fit installation

Compatibility

Designed as an OEM-style replacement or original installation component for drill jigs and fixture plates requiring a headless press fit bushing with a 0.75 inch bore and 1 inch body outside diameter per ANSI standards.

Installation Notes

Press fit drill bushings are typically installed by toolmakers or machinists using an arbor press. The receiving hole in the jig plate must be machined to the appropriate tolerance to achieve proper press fit retention. Verify bore and plate hole dimensions before pressing to avoid bushing movement or damage to the jig. Once pressed in, this bushing is not designed for removal and reuse.
