Product features
●Most suitable for forged and thermal refined high carbon steels (C48 ～ C55) with 20 ～ 30 HRC hardness.
●MHSL ensures long tool life by adopting HSS-Co material of high wear resistance and special coating.
Cemented
Carbide Taps


●Adopting proprietary flute design, MHSL ensures consistent chip ejection in the area of middle tapping speed,
and improves surface roughness of internal threads.
