Can anyone recommend speed and feed for a M42 cobalt, 4.000 diameter jeweler slitting saw, 1.000 arbor, .022 thick, 150 teeth. There is a .100 thick 3.000 spacer on each side of the blade to help with rigidity. The material I am cutting is stainless steel. I am making a cutting through a .075 web at .100 deep. This is a continuous cut, there is a .200 gap between each wall to cut through.
