Milling Cutter:
Compression Mill
A compression end mill has an up-cut flute geometry from the tip to usually about 1/3 of the cutter length at which point it converts into a down-cut flute. The advantage is that the end mill, when used properly, will give you a nice clean top and bottom finish on your work piece.聽 Typically used in laminated materials to prevent delamination when cutting.
