The AMG coated 4-flute ball nose end mill features a four-flute design that ensures even distribution of cutting forces, reducing cutting vibration and improving surface finish during machining. Combined with nano-coating technology, it maintains low friction and stable chip evacuation even during high-speed and high-temperature machining, extending tool life and reducing tool change frequency.

Through AMG's precision regrinding technology, the tool's sharp cutting edges are restored while applying a uniform, wear-resistant coating, enhancing the tool's stability under high temperatures and heavy loads. The four-flute design allows for smooth chip evacuation and low vibration during cutting, effectively protecting the mold surface and improving machining surface finish and efficiency.
It is specially designed for mold machining, medical parts machining, automotive components, and high-precision structural parts, helping customers achieve a high-efficiency, high-finish, and high-stability cutting experience.

【Applications】
Ideal for high-speed semi-finishing and finishing of mold cavity surfaces, precision parts, medical device components, automotive molds, aerospace aluminum parts, and titanium alloy workpieces. These tools provide efficient and stable solutions for complex profiles and curved surface machining, effectively improving surface finish while extending tool life. They are also suitable for regrinding, helping users save production costs and tool change time.
