I am trying to model the T-Slot Milling Cutter(image below). I am not sure how to get the 10° helix angle(the alternating teeth). I know I'm gonna need some planes, but I'm not sure how to put those planes in. If anyone has some suggestions that'd be appreciated.

Attached is an image of what I'm trying to model, a 2018 file that has no helix angle and another with an attempted plane.
