Threading Die MODECO M20 MN-62-150 — external thread cutting tool M20

MODECO Threading Die M20 (external) is a hand-operated tool designed for cutting and restoring metric external threads sized M20. The die is intended for use in manual operations or mounted in appropriate holders for machine-assisted work. It provides accurate thread profiling for bolts, studs and shafts where an M20 external metric thread is required, and is suitable for general repair, maintenance and fabrication tasks.

Advantages

The solid construction ensures consistent cutting performance and dimensional stability across repeated uses. Machining tolerances and tooth geometry are optimized for clean chip evacuation and reduced thread burr formation. The die is compatible with standard die holders and clamping fixtures, allowing safe and stable operation when used by hand or with machine support.

Suitable for

• Cutting new M20 external metric threads on bolts and studs
• Restoring damaged or worn M20 external threads
• On-site repair and maintenance of mechanical assemblies
• Small-scale workshop thread cutting and rethreading tasks

Key specifications

• Thread type: external metric thread M20
• Intended use: manual or machine-assisted threading
• Compatibility: designed for use with standard die holders and clamping fixtures
• Application: suitable for bolts, studs and shafts requiring M20 threads

How to use

Secure the workpiece so it cannot rotate. Mount the die in a compatible die holder or chuck, aligning it squarely to the workpiece axis to ensure concentric threading. Apply cutting lubricant to the blank or damaged thread to reduce friction and improve chip removal. Start the die onto the blank by hand to engage the thread grooves, then advance with steady, even pressure. For deep or long threads, periodically reverse the die slightly to break chips and clear swarf. After cutting, clean the threaded area and inspect the profile for dimensional accuracy.

Usage recommendations

Use appropriate cutting lubricant for the material being worked (e.g., oil for steel, specialized lubricants for stainless steel or non-ferrous metals). Ensure the die is properly aligned and secure in the holder to avoid cross-threading. For precision fits, perform a trial cut on a sacrificial blank and measure thread dimensions before final use.
