Boneham H406KG Press Fit Headed Drill Bushing 13/32 Id

Product Description

The BONEHAM H406KG is a Type H press fit headed drill bushing designed to guide cutting tools with precision during drilling, reaming, and boring operations. It features an inside diameter of 13/32 inches, a body outside diameter of 5/8 inches, and a length under head of 3/8 inches. Constructed from steel hardened to 60 to 65 HRC, this bushing delivers the wear resistance and dimensional stability required in production jig and fixture applications. The headed design provides a positive stop against the jig plate surface, ensuring consistent tool guidance and depth control across repeated operations.

This bushing is suited for use in drill jigs and fixture plates in manufacturing and machining environments. It is pressed directly into the jig body and is not designed for removal and replacement after installation, making it appropriate for fixed, high-volume production setups. Machinists, tool and die makers, and jig and fixture builders are the primary installers. The bushing conforms to ANSI standards for drill bushing geometry and tolerancing.

Key Features

• Press fit installation method — no liner or lock required, installs directly into jig plate
• Inside diameter tolerance of +0.0001 to +0.0005 inches for precise tool guidance
• Steel construction hardened to 60 to 65 HRC for wear resistance in repetitive drilling operations
• Headed design with head outside diameter of 51/64 inches and head height of 7/32 inches for positive axial positioning
• ANSI-compliant geometry for interchangeability with standard Type H drill bushing specifications
• Non-renewable design suited for permanent installation in fixed production jigs

Compatibility

Designed as an ANSI-standard Type H press fit headed drill bushing for use in drill jigs and fixture plates requiring a permanent, non-renewable bushing installation.

Installation Notes

Installation is performed by pressing the bushing into a properly sized and toleranced hole in the jig plate using an arbor press or hydraulic press — do not drive with a hammer, as this can damage the bushing bore or alter its alignment. The receiving hole in the jig plate must be machined to the correct press fit tolerance to achieve proper retention. Verify bore alignment before pressing to final depth. This bushing is not designed for removal once installed; plan jig layout accordingly before pressing.
