Boneham H6416NC Press Fit Headed Drill Bushing Steel

Product Description

The BONEHAM H6416NC is a Type H press fit headed drill bushing machined from steel and hardened to 60 to 65 HRC. It is designed to guide drill bits with precision in jig plate applications where consistent hole location is critical across repeated operations. The bushing features a 0.75 inch (0.7500 inch) inside diameter, a 1 inch body outside diameter, and a 1 inch length under the head. The head outside diameter measures 1-15/64 inches with a head height of 5/16 inch. It is installed by press fit and does not require a liner bushing. Machinists, tool and die makers, and jig builders install this component during fixture fabrication or maintenance.

This bushing is suited for production drilling fixtures, jig plates, and tooling assemblies where a permanent, non-renewable guided bushing is required. Its hardened steel construction resists wear from repeated drill passes, making it appropriate for moderate to high-volume production environments. The headed design seats against the top surface of the jig plate, providing positive axial location without additional fasteners. It is a direct fit in applications calling for an ANSI-standard Type H headed press fit bushing with 0.75 inch bore.

Key Features

• Type H press fit installation — no liner bushing required
• Inside diameter 0.75 inch with tolerance of plus 0.0001 to plus 0.0005 inch for precise drill guidance
• Hardened steel body at 60 to 65 HRC for extended wear life
• Head outside diameter 1-15/64 inches, head height 5/16 inch for positive axial seating
• Meets ANSI standards for drill bushing geometry and tolerances
• Non-renewable (fixed) design for permanent fixture installations

Compatibility

Designed as an ANSI-standard Type H press fit headed drill bushing for use in jig plates and drilling fixtures requiring a 0.75 inch bore and 1 inch body outside diameter.

Installation Notes

Press fit bushings are typically installed by a machinist or tool maker using an arbor press or hydraulic press — do not hammer directly on the bushing head. The receiving bore in the jig plate must be machined to the appropriate interference fit tolerance before installation. Ensure the fixture plate is secured and supported to avoid distortion during pressing. Once installed, this bushing is not designed for removal or replacement.
