Eagle Cutting Tool MHD-040-070-I Metric Hex Die M4.00x0.70

Product Description

The EAGLE CUTTING TOOL MHD-040-070-I is a carbon steel metric hex die sized for M4.00x0.70 thread cutting applications. Hex dies fit standard hex die stocks and are turned with a wrench or die holder to cut or rethread external threads on bolts, rods, and fasteners. This die is an import-grade tool suited for general shop use, maintenance operations, and production threading tasks where cost efficiency matters. The M4.00 designation indicates a 4 mm nominal thread diameter, and the 0.70 pitch indicates 0.70 mm between thread crests, conforming to standard coarse metric thread specifications.

This die is used in metalworking, maintenance, and repair operations where M4 coarse metric external threads need to be cut or restored. Typical applications include threading machine screws, repair studs, and small-diameter rod stock. It is appropriate for use in light manufacturing, tool rooms, HVAC equipment assembly, and general mechanical maintenance shops. The hex body style allows direct engagement with a wrench for controlled torque application in tight spaces or when a standard round die stock is not available.

Key Features

• M4.00x0.70 thread form for standard coarse metric external threading
• Hex body design fits hex die stocks and standard wrenches
• Carbon steel construction provides adequate hardness for threading mild steel and soft metals
• Import grade offers cost-effective performance for general-purpose and maintenance use
• Compact form factor suited for small-diameter fastener threading

Compatibility

Designed for use with standard hex die stocks and wrenches sized to accept hex dies. Cuts M4.00x0.70 coarse metric external threads on mild steel, aluminum, brass, and similar machinable materials.

Installation Notes

Threading dies should be installed and used by machinists or maintenance technicians familiar with hand threading operations. Secure the workpiece firmly before applying the die to prevent movement during thread cutting. Apply cutting oil or threading fluid to the die and workpiece to reduce friction, extend tool life, and improve thread quality. Inspect the die for wear or chipping before each use and replace if thread form is degraded.
