Boneham H164CY Press Fit Headed Drill Bushing Steel

Product Description

The BONEHAM H164CY is a Type H press fit headed drill bushing used to guide cutting tools with precision during drilling operations. It features an inside diameter of 0.098 inches (Wire Gauge 40) and a body outside diameter of 0.25 inches. The head outside diameter measures 23/64 inches with a head height of 3/32 inches and a length under head of 0.25 inches. Constructed from steel hardened to 60 to 65 HRC, this bushing delivers the bore accuracy and wear resistance required in production jig and fixture applications. Machinists, toolmakers, and fixture builders use this component to maintain consistent hole location across repeated drill cycles.

This bushing is suited for use in drill jigs and tooling fixtures found in machine shops, fabrication facilities, and production floor environments. It installs directly into a prepared hole in the jig plate without a locking liner, making it appropriate for fixed, single-operation setups where the bushing is not intended to be removed during service. The headed design seats flush to a counterbore shoulder or sits proud of the jig plate face depending on the fixture design.

Key Features

• Type H press fit installation — no locking liner or lock notch required
• Inside diameter of 0.098 inches with a tight tolerance of +0.0001 to +0.0004 inches for consistent tool guidance
• Steel construction hardened to 60 to 65 HRC for extended wear life
• Head outside diameter of 23/64 inches provides positive seating against jig plate surface
• Meets ANSI standards for drill bushing geometry and dimensional accuracy
• Non-renewable design for permanent or long-run fixture installations

Compatibility

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

Installation Notes

Press fit bushings are installed by toolmakers or machinists using an arbor press or similar equipment — never drive with a hammer directly on the head. The receiving hole in the jig plate must be machined to the correct press fit tolerance before installation. Once pressed in, this bushing is not designed for field removal or replacement. Confirm the jig plate hole depth and diameter against the bushing dimensions before pressing to seat.
