Boneham AM00000242 Press Fit Headless Drill Bushing Hm

Product Description

The BONEHAM AM00000242 is a press fit headless drill bushing in industry code HM, designed to guide drill bits with precision in jig and fixture applications. The bushing features a 6.9-inch inside diameter and is constructed from steel for durability and dimensional stability under repeated use. It installs without a head, sitting flush with or below the jig plate surface to minimize obstruction. Machinists, toolmakers, and fixture builders install this bushing type when a low-profile guide is required and tool clearance above the plate is limited.

This bushing is suited for use in drill jigs, production fixtures, and tooling plates where consistent hole location is critical. The headless design makes it appropriate for applications where a flange would interfere with the workpiece or adjacent tooling. It is pressed into a precision-reamed hole in the jig body and is not intended to be renewed or replaced in service. Typical environments include machine shops, production facilities, and industrial tooling operations.

Key Features

• Press fit installation method for secure, permanent seating in the jig plate
• Headless HM industry code design provides a flush or sub-flush profile
• 6.9-inch inside diameter for consistent drill guidance
• Steel construction for wear resistance and dimensional stability
• Non-renewable design suited for permanent fixture integration

Compatibility

Designed as an OEM-style replacement or new-installation component for drill jigs and tooling fixtures requiring an HM-code press fit headless drill bushing with a 6.9-inch inside diameter.

Installation Notes

Installation is performed by toolmakers or machinists using a press to seat the bushing into a precision-reamed hole in the jig plate. Ensure the receiving hole is machined to the correct tolerance for an interference fit before pressing. Do not hammer the bushing in freehand, as this can damage the bore or misalign the bushing. Once pressed in, the bushing is not intended to be removed or reused.
