1. Origin of the Name
The most distinctive feature of the ball nose end mill is its tip part, which presents a round arc shape, resembling the shape of a nose, hence the name "ball nose." This round arc design allows the tool to cut materials smoothly during the machining process, particularly when performing three-dimensional curved surface processing, resulting in a high-quality surface finish.

2. Product Features
① Dual round arc and helix angle design make the end mill more wear-resistant; during processing, it reduces product burrs and enhances surface smoothness.
② The adoption of a suitable negative rake angle design balances the strength and sharpness of the cutting edge. Additionally, a large core diameter is used to enhance the tool rigidity, ensuring stable cutting and chip evacuation.
③ Large chip evacuation space: The larger capacity chip slot provides powerful cutting and smooth chip discharge. This achieves high-efficiency machining with higher precision and a more lustrous finish on the workpiece.
④ Easy chamfering operation: The chamfered layout at the shank part makes clamping easier, with a smooth and bright chamfer. The craftsmanship is outstanding, creating a rounded, solid, and aesthetically pleasing application.
