Boneham H326HX Press Fit Headed Drill Bushing 9/32 Id

Product Description

The BONEHAM H326HX is a Type H press fit headed drill bushing designed to guide drill bits and cutting tools with precision during machining and fabrication operations. It features a 9/32 inch inside diameter and a 1/2 inch body outside diameter, with a 3/8 inch length under the head. The head outside diameter measures 39/64 inch and the head height is 7/32 inch. Manufactured from steel and hardened to 60 to 65 HRC, this bushing delivers consistent bore alignment and resists wear under repeated drilling cycles. The press fit installation method provides a secure, permanent mount without additional fasteners. Inside diameter tolerance is held to +0.0001 to +0.0005 inch for accurate tool guidance.

This bushing is suited for use in drill jigs, fixtures, and production tooling setups where repeatable hole location is required. It is a non-renewable bushing intended for permanent installation in jig plates. Typical users include machinists, tool and die makers, and fabrication shops running moderate to high-volume drilling operations on ferrous and non-ferrous workpieces. It is ANSI-compliant and appropriate for industrial and precision manufacturing environments.

Key Features

• Inside diameter of 9/32 inch with tight tolerance of +0.0001 to +0.0005 inch for accurate tool guidance
• Steel construction hardened to 60 to 65 HRC for wear resistance under repeated drilling
• Body outside diameter of 1/2 inch with head outside diameter of 39/64 inch
• ANSI-compliant for use in standard jig and fixture applications
• Non-renewable, non-counterbored configuration for simplified permanent installation

Compatibility

Designed as an OEM-style replacement and standard fitment for Type H press fit headed drill bushing applications conforming to ANSI specifications in drill jig plates and machining fixtures.

Installation Notes

Press fit bushings are installed by machinists or toolmakers using an arbor press or drill press with appropriate pressing fixtures. The jig plate bore must be machined to the correct interference fit tolerance before pressing the bushing into position. Do not hammer the bushing directly without a pressing block, as this can damage the head or alter the bore geometry. Once pressed in, this bushing is not intended for removal or reuse.
