Features
● Most suitable for forgings and thermal refined steels of S48C-S55C (20-30HRC)
● MHSL ensures a long tool life by adopting HSS material of high wear resistance, and special coating.
● Adopting proprietary flute design, MHSL ensures consistent chip ejection in the area of middle tapping speed, and improves surface roughness of internal threads.
