Helical Milling question

[tsaladyga]

Hi guys,
I am new to Pro Manufacturing. I have wildfire 4.0. My question is.
I am trying to program a helical milled counter bore. the dia. is .938, the depth is .100. I am using a 1/2" hss em. Not sure what to pick as my milling option. I have tried trajectory milling, but I can only plunge mill it. I would really like to grasp the concept of helical entry milling.
Any advice would be Great!
Thanks

I use a volume milling sequence to rough counter bores out then a surface mill sequence (cut lines, closed loops) and a helical path to finish.
