Boneham H164DV Press Fit Headed Drill Bushing

Product Description

The BONEHAM H164DV is a Type H press fit headed drill bushing designed to guide drill bits with precision in jig and fixture applications. Manufactured from steel and hardened to 60 to 65 HRC, this bushing provides consistent bore guidance and long service life under repeated drilling cycles. The inside diameter measures 0.125 inches with a tight tolerance of plus 0.0001 to plus 0.0004 inches, ensuring accurate bit alignment. The body outside diameter is 0.25 inches, the length under the head is 0.25 inches, and the head outside diameter measures 23/64 inches. Machinists, tool and die makers, and precision fabricators install this bushing as a permanent press fit component in drill jigs and fixtures.

This bushing is suited for production drilling operations where a fixed, non-renewable guide is appropriate. It is pressed directly into a jig plate and remains in place for the life of the fixture. Typical applications include repetitive hole drilling in metal fabrication, assembly jigs, and inspection fixtures where consistent hole location is critical. The headed design seats the bushing flush against the jig plate surface, providing a positive stop during installation.

Key Features

• Type H press fit design installs permanently into drill jig plates without liners
• Steel construction hardened to 60 to 65 HRC for wear resistance under repeated drilling
• Inside diameter tolerance of plus 0.0001 to plus 0.0004 inches for precise bit guidance
• Headed design provides a positive seating stop against the jig plate surface
• Meets ANSI standards for drill bushing dimensions and tolerances
• Non-renewable fixed installation suitable for high-volume production jigs

Compatibility

Designed as an ANSI-compliant Type H press fit headed drill bushing for use in standard drill jig plates and fixtures requiring a 0.25-inch body outside diameter press fit bore.

Installation Notes

Installation is performed by pressing the bushing into a prepared jig plate bore using an arbor press or hydraulic press. The receiving bore should be machined to the appropriate interference fit tolerance before pressing. Ensure the jig plate is secured and supported to prevent distortion during pressing. This is a permanent installation; the bushing is not intended for removal or replacement once pressed in.
