total of 4 inches of steel out of position. It does seem that the smaller bits are slower than the larger ones up to a point. It will cut the 3/8 that fast but a guy couldn't do it continuously. I was wondering though from the machinists if there would be better or as good alternative to cutting oil. Lots of difference when it gets to greater thickness, bit gets hotter in deep holes, these holes were inch thick.

The solid carbide end mill did the job going through the hardened spider gears. I took it easy with .025 each pass to a depth of .375. It was like "butta". Thanks for the info guys.
