I need to slit a piece of mild steel 0.500" thick and 0.875 deep to a
0.652 hole. This will be a clamp to attach to a motor shaft. Never
used a slitting saw before, therefore I am asking for any advice.
Using a drill/mill with a 3X1/16X1 30 tooth saw. Thanks in advance

I hate slitting saws! Slow feed, robust rigid set-up, flood coolant, silent
prayers! Can you use a hacksaw or a Sawsall?
