Eagle Cutting Tool MHD-390-300-I Metric Hex Die M39.0x3.00

Product Description

The EAGLE CUTTING TOOL MHD-390-300-I is a carbon steel metric hex die used for cutting external threads on round stock. This die is sized for M39.0 threads with a 3.00 mm pitch, making it suited for large-diameter threading work in fabrication, maintenance, and repair applications. The hex body profile allows secure seating in a standard die stock or holder. Machinists, pipefitters, and maintenance technicians rely on this die for field and shop threading of metric fastener stock and threaded rod.

This die is designed for use in industrial and commercial environments where large metric threads must be cut or restored. It is a common choice for heavy equipment fabrication, structural assembly, and maintenance operations where M39 metric threading is required. The import designation indicates this is a value-tier tooling option suited for lower-volume or occasional threading tasks rather than high-production runs.

Key Features

• M39.0 x 3.00 mm pitch for large-diameter metric external threading
• Hex body profile seats securely in standard hex die stocks and holders
• Carbon steel construction suitable for threading mild steel and similar materials
• Single-die format for direct replacement or supplemental tooling use

Compatibility

Designed as a replacement or supplemental hex die for standard die stocks and holders accepting the appropriate hex body size for M39.0 threading applications.

Installation Notes

This die is installed by a machinist or qualified maintenance technician using a compatible hex die stock. Secure the die firmly in the stock before beginning thread cutting, and apply appropriate cutting fluid to reduce heat and improve thread quality. Inspect the die for wear or chipping before each use, and ensure the workpiece is properly supported and clamped. Follow shop safety practices when operating threading tools.
