I wanted a set of 90 degree countersinks to gently deburr steel by hand . They were closer to 85.5 degrees when I got them and they didn't even cut it. I tried them on aluminum and got a sticky mess. Just in case I checked their hardness with a file, my file went in pretty easily. Not suitable for cutting tool.
