I acquired a 3"X3" drop of 1" steel that i assumed was A36, i applied my brand new fly cutter to practice squaring up stock it was ruff cut (oxy acetylene cut) so lots of ruff edges, so i'm thinking great i can get lots of practice on some free material. I took the fly cutter (without shaping the HSS and started on it, this absolutely ate the the HSS. I then sharpened some 1/4" HSS (cheap from HF) put clearances on all sides needed and sharpened it with diamond hone, then the steel ate this HSS also. i then switched to a 3/8 carbide 4 flute end mill (cheap amazon) and after cutting some, broke off the ends of the flutes, i then switched to 12mm HSS 4 flute and this cut the steel but it dulled very quickly.
Is it possible that this is not A36 or am i just using crappy tools/technique?
