Boneham H1616EG Press Fit Headed Drill Bushing

Product Description

The BONEHAM H1616EG is a Type H press fit headed drill bushing designed to guide cutting tools with precision in fixed jig and fixture applications. Machined from steel and hardened to 60 to 65 HRC, this bushing resists wear through high-cycle drilling, reaming, and boring operations. The inside diameter measures 9/64 inches with a tolerance of +0.0001 to +0.0004 inches, holding tight positional accuracy for repeatable hole location. The body outside diameter is 1/4 inch, the length under the head is 1 inch, and the head outside diameter is 23/64 inch with a head height of 3/32 inch. The counterbored head seats flush or recessed into the jig plate for a stable, low-profile installation. This part is non-renewable and intended as a permanent press fit component.

The H1616EG is suited for use in drill jigs and tooling fixtures in metalworking, manufacturing, and precision machining environments. It is installed by tool and die makers, fixture builders, and machine shop technicians working with drill jig assemblies where accurate, repeatable hole guidance is required. The pressed-in design eliminates bushing rotation during operation, making it appropriate for fixed-station drilling setups where tool position does not change between production runs.

Key Features

• Type H press fit headed design for permanent installation in drill jig plates
• Inside diameter of 9/64 inches with a close tolerance of +0.0001 to +0.0004 inches
• Hardened steel construction at 60 to 65 HRC for extended wear resistance
• Counterbored head seats flush or below the jig plate surface
• Conforms to ANSI standards for drill bushing geometry and fit
• Non-renewable construction — intended for permanent press fit service

Compatibility

Designed as an ANSI-standard Type H press fit headed drill bushing for use in drill jigs and fixture plates requiring a 1/4 inch body outside diameter and 9/64 inch bore.

Installation Notes

Installation is performed by pressing the bushing into a precision-reamed hole in the jig plate using an arbor press or hydraulic press — never drive with a hammer directly on the bushing head. Verify the receiving bore diameter and surface finish meet ANSI press fit specifications before installation. Once pressed in, the H1616EG is not designed for removal and reuse. Always de-energize and lock out any machine the jig is mounted to before replacing or inspecting bushings.
