Broaching ETD 150

[pdybeck]

I am interested in anyone's experience in broaching ETD 150. The broach would be between a 3/8" - 1/2" Hex by 1/2" deep. Material hardness of ETD 150 may pose difficulties in broaching, but I am not sure as it seems to be on the edge. Does anyone have any experience?

It will be similar to 4140 HT. Slower speeds, shorter depths of cut, and a good setup will provide success
