RUKO SCE-DIN223-MF8x1.0mm Round Die Metric Fine Thread M8 x 1.0 mm HSS-G

This RUKO round die is engineered for precision cutting of metric fine threads with a nominal diameter of M8 and a pitch of 1.0 mm. Unlike standard dies, it is manufactured to DIN 223 and ground from HSS-G for sharp, accurate threads in steel, cast iron, and non-ferrous metals up to 800 N/mm² hardness.

Highlights

• Metric fine thread M8 x 1.0 mm, tolerance class 6g
• Ground HSS-G for high precision and long life
• Right-hand cutting direction, 3 flutes for efficient chip removal
• Outer diameter 25 mm, thickness 9 mm, fits standard die stocks

In daily use

The bright, uncoated finish reduces friction and allows easy threading in manual or low-speed machine operations. A 60° thread profile ensures compatibility with standard metric fine fasteners.
