Boneham H4016KK Press Fit Headed Drill Bushing

Product Description

The BONEHAM H4016KK is a Type H press fit headed drill bushing designed to guide cutting tools with precision during drilling, reaming, or boring operations. It features a 27/64 inch inside diameter and a 5/8 inch body outside diameter, with a 1 inch length under the head. Machined from steel, this bushing is pressed directly into a jig plate without a locking mechanism, making it a fixed, non-renewable installation. It is suited for production and tooling applications where repeatable hole location accuracy is required. Licensed machinists and tooling specialists install this component as part of drill jig assemblies in industrial and manufacturing environments.

This bushing is used in drill jig applications across metalworking, fabrication, and precision machining operations. The headed design allows the bushing to seat flush against the jig plate surface, preventing it from being pushed through during tool pressure. It is appropriate for both light and moderate production runs where a permanent, press-in bushing is preferred over a renewable or slip-fixed style. The Type H industry code designates this as a standard headed press fit configuration.

Key Features

• Press fit installation — no locking collar or set screw required
• Headed (Type H) design seats against jig plate surface to resist axial push-through
• 27/64 inch inside diameter with a close tolerance of +0.0001 to +0.0005 inches for precise tool guidance
• 5/8 inch body outside diameter with a 51/64 inch head outside diameter
• 7/32 inch head height for low-profile fitment in tight jig configurations
• Steel construction for durability in repetitive drilling cycles

Compatibility

Designed as a standard Type H press fit headed drill bushing for use in drill jig plates and tooling fixtures where a permanent, non-renewable bushing is required.

Installation Notes

This bushing is installed by machinists or tooling technicians using an arbor press or similar pressing equipment — never hammer it in freehand, as this can damage the bore tolerance or distort the jig plate hole. Ensure the jig plate bore is machined to the correct interference fit diameter before pressing. Once installed, this bushing is not designed to be removed and reused. Follow applicable shop tooling standards and jig design specifications for proper bushing placement and plate thickness.
