Boneham AM00000083 Press Fit Headless Drill Bushing Hm

Product Description

The BONEHAM AM00000083 is a press fit headless drill bushing in the HM industry code classification. It is designed to guide drill bits and boring tools with precision in jig and fixture applications. The bushing presses directly into a drill jig plate without a flange or head, producing a flush, clean surface on the workpiece side. Manufactured from steel, it delivers the hardness and wear resistance required for repetitive drilling operations in machine shop and fabrication environments. With a 2.8 inch inside diameter, it accommodates large-bore tooling requirements. Machinists, tool-and-die makers, and fixture builders are the typical installers.

This bushing is suited for use in drill jig fixtures where headless, flush-mount installation is required. The HM designation indicates it follows standard jig bushing industry dimensions, making it a common choice for production drilling setups in both job shop and manufacturing floor environments. Its steel construction supports use with high-speed steel and carbide drill bits across a range of materials. This part is sold individually and is not a renewable or slip-renewable type — it is intended as a fixed, permanently pressed installation.

Key Features

• Press fit installation — no flange, seats flush with jig plate surface
• HM industry code classification for standardized dimensional compatibility
• 2.8 inch inside diameter for large-bore drilling applications
• Steel construction for hardness and long service life under repeated tooling contact
• Non-renewable design — permanently pressed into fixture plate

Compatibility

Designed as an OEM-style replacement or new-installation component for drill jig fixtures requiring a press fit headless bushing with HM industry code dimensions and a 2.8 inch inside diameter.

Installation Notes

Press fit bushings are installed by machinists or tool-and-die makers using an arbor press or hydraulic press to seat the bushing flush into the jig plate bore. Ensure the receiving hole in the jig plate is machined to the proper interference fit tolerance before pressing. Do not drive the bushing with a hammer directly on the bore edge, as this can damage the inside diameter and affect drill guidance accuracy. Once pressed in, this bushing is not designed to be removed and reused.
