About Square End Mills

Create features with sharp inside corners using square end mills, which have a square nose at the tip of the tool. Square end mills are commonly used for counterboring, side and face milling, and milling square shoulders.

In general, end mills with more flutes allow a higher feed rate, while end mills with fewer flutes permit faster chip clearance. For best results, choose the shortest end mill that will work for your application.
