Ronddraadsnijijzer M20 DIN 22568 (6g) HSS 800

This round threading die cuts precise M20 metric coarse threads with a 2.5 mm pitch, delivering a 6g tolerance class for reliable external threading in steel, cast iron, and non-ferrous metals. Its ground threads from high-speed steel ensure clean, accurate cuts and long tool life, making it a dependable choice for both manual and machine operations.

Advantages

The die's HSS construction provides excellent wear resistance and heat tolerance, maintaining sharpness through repeated use. Ground threads produce smooth, dimensionally stable threads that meet DIN 22568 standards, reducing the need for rework. The bright finish resists corrosion and simplifies chip evacuation, while the right-hand cutting direction suits standard threading tasks.

Suitable for

• Creating external threads on bolts, studs, and shafts in maintenance and repair work
• Manufacturing threaded components in metalworking shops and production lines
• Rethreading damaged or worn M20 fasteners to restore functionality
• Use with a DIN 225 die stock for manual threading or in a machine setup
