Can the vertical cutter be drilled through the center edge?
Divided vertical and four edged blade, the four blade is not, if 2 edges can be drilled, but the effect is not good
Yes, but the feed will be small,
The end edge of the flat end milling cutter can drill hollow through the center point.Generally, however, it is not recommended to drill directly with the end mill.You can drill with the drill bit first, and then use the end mill to enlarge the hole. A 3 edged flat end mill is recommended.
