Boneham AM00000034 Press Fit Headless Drill Bushing Hm

Product Description

The BONEHAM AM00000034 is a press fit headless drill bushing in the HM industry code series, manufactured from hardened steel for use in jig and fixture tooling applications. The bushing features a 13.5-inch inside diameter with a close-tolerance bore (+0.006/+0.017 mm) to guide drill bits and cutting tools with precision. A surface hardness of 60 to 65 HRC provides wear resistance during high-cycle drilling operations. This is a non-renewable, fixed-style bushing installed by press fitting directly into a drill jig plate or fixture body. Machinists, toolmakers, and fixture builders are the primary installers.

This bushing is suited for production drilling setups in machine shops, fabrication facilities, and tooling rooms where repeatable hole location accuracy is required. The HM designation indicates a headless, press fit style that sits flush with the jig plate surface. Its steel construction and hardened bore make it appropriate for ferrous and non-ferrous workpiece materials. It ships individually and carries an ANSI-compliant design, making it a direct fit for standard drill jig fixture plates built to ANSI specifications.

Key Features

• Press fit installation method for secure, flush-mount seating in jig plates
• HM industry code designation — headless, fixed-style bushing
• 13.5-inch inside diameter with precision bore tolerance of +0.006/+0.017 mm
• Hardened steel construction, 60 to 65 HRC for extended wear life
• Non-renewable fixed bushing — designed for permanent installation
• ANSI-compliant design for compatibility with standard tooling fixtures

Compatibility

Designed as a press fit replacement or new-build component for ANSI-standard drill jig fixtures requiring an HM-series headless drill bushing with a 13.5-inch inside diameter bore.

Installation Notes

Installation is performed by toolmakers or machinist trades using an arbor press to seat the bushing flush into a pre-machined jig plate bore. The receiving bore in the fixture plate must be machined to the correct interference fit tolerance before pressing in the bushing. Do not hammer the bushing directly without a press sleeve, as this can damage the bore or distort the bushing body. Once pressed in, this bushing is not designed for removal and reinstallation.
