RUKO SCE-DIN22568-HSS-M3x0.50mm Left-Hand Round Die

This round die stands out for its left-hand thread cutting capability in M3 size with a fine 0.50 mm pitch, making it the go-to choice for creating reverse-threaded fasteners where standard right-hand dies cannot be used. Manufactured from high-speed steel and conforming to DIN 22568, it delivers clean, precise threads in unalloyed and low-alloyed steels as well as non-ferrous metals.

Highlights

• Left-hand metric ISO thread M3 × 0.50 mm
• High-speed steel (HSS) for durability and sharpness
• DIN 22568 compliant for reliable interchangeability
• Bright finish for corrosion resistance and smooth cutting
• Requires a die stock for operation

In daily use

When you need to cut external left-hand threads on small components, this die provides consistent results. Its 20 mm outer diameter and 7 mm thickness fit standard die stocks, and the 6g tolerance class ensures the threaded part meets common engineering fits. Suitable for materials up to 800 N/mm² tensile strength.
