These bits are amazing! I have tried all types of bits and these are the best bits in the range. They're made in the USA, they come and stay sharp! I drill and tap mild steel, hot and cold roll (with Tap Magic) all day and it goes on and on. It contains 8% cobalt, which is way better than most big stores which typically contain 5%.
