Eagle Cutting Tool MHD-450-450-I Carbon Hex Die M45x4.5

Product Description

The EAGLE CUTTING TOOL MHD-450-450-I is a carbon hex die designed for cutting M45x4.5 metric external threads. This is a specialty threading die intended for large-diameter metric applications where standard off-the-shelf dies are not commonly stocked. It is built in a hex body configuration, which seats in a matching hex die stock for controlled, repeatable thread cutting. Machinists, pipe fitters, and maintenance technicians working on heavy industrial or specialty mechanical assemblies will find this die applicable when M45x4.5 pitch threading is required on rod, bolt stock, or round bar stock.

This die is suited for applications requiring a coarse 4.5 mm pitch on a 45 mm nominal diameter thread profile. The hex body form makes it compatible with standard hex die stocks. It is classified as a special-run die, meaning it is intended for non-standard metric thread sizes that fall outside the common M1 through M36 range typically stocked in general tooling inventories. Industrial maintenance shops, toolrooms, and specialty fabrication operations are the primary environments where this die sees service.

Key Features

• M45x4.5 metric thread specification for large-diameter external thread cutting
• Hex body design seats securely in a standard hex die stock for positive drive
• Carbon steel construction suitable for threading mild steel, aluminum, and similar materials
• Special-run die for non-standard metric thread sizes not commonly found in standard die sets
• Minimum order quantity of 1 unit, available as a single piece

Compatibility

Designed for use with hex die stocks sized to accept a large-diameter hex die body. Verify die stock hex opening dimensions before ordering, as M45-range hex dies require a correspondingly large die stock. No specific compatible model numbers were provided in the product data.

Installation Notes

Thread cutting with a hex die should be performed by a qualified machinist or maintenance technician familiar with metric threading standards. Ensure the workpiece is properly secured and the die stock is correctly sized for the hex die body before beginning. Apply a suitable cutting fluid throughout the threading operation to extend die life and produce a clean thread form. Inspect the finished thread with a metric thread gauge to confirm pitch and fit before final assembly.
