    What Is Face Milling and Why Should You Bother?

    End Mills. Using an end mill to do face milling is often inefficient, but can create some appealing patterns in your finish, if that’s what you’re after. An end mill often comes to a sharp point at one corner and the bottom edge is usually at a 1 angle as it goes to the center, so it doesn’t overlap with the previous pass
