Why can’t the end mill be cut vertically?

End mills may not be able to cut vertically. Only an end mill with a center edge can be cut vertically, but this processing method is rarely used. Because the midpoint of the bottom edge of the end mill is relatively static when it rotates, it does not have any cutting and chip removal properties, and it is easy to cause the end mill to break.

The ordinary taper shank end milling cutter is mainly used for transverse milling. The main part of its cutting is on the side edge of the circumference of the end milling cutter. The center of its end tooth has a center hole and cannot feed down vertically. The function of the end tooth is only to sweep the bottom surface; The main function of the keyway milling cutter is to mill the keyway. There is no central hole in the center of the end tooth of the keyway milling cutter, and the cutting edge of the end tooth of the keyway milling cutter is a positive rake angle, so that when milling the keyway, the cutter can directly feed down without the fitter drilling the tool hole again.
