Actually the one I have works great on S.S. screws.
When I mounted my windscreens & sunvisers I drilled & tapped my windsheild side frames 10/32 for the sidescreens. I was able to cut & trim very small portions off the S.S. screws to obtain a perfectly flush fit to the inside of the frame. The cut was of such quality I did not even have to touch up the end of the screw.
I will admit it does take considerable more force to cut S.S. but the simplicity of it makes it worthwhile.
