Working Principle
The 12-flute design provides increased cutting contact area and
improved rigidity, which enhances vibration resistance during the
machining of tough materials. The SA coating reduces friction and
heat buildup between the tool and stainless steel, improving chip
evacuation and wear resistance—keep stable performance even under
high-speed, heavy-load machining conditions.
FAQ
Q: Can the flute length or coating be customized?
A: Yes, AMG provides custom solutions based on customer drawings or
application requirements.
Q: How long does the tool last when machining stainless steel?
A: Under optimal cutting parameters, tool life exceeds that of
standard coated end mills by more than 20%.
Q: Is it suitable for dry cutting?
A: Yes, the SA coating is designed for excellent dry-cutting heat
resistance and oxidation protection. It is suitable for both dry
and wet machining.
