Drill a hole in the square pipe of 2.3 t.

I bought 48 holes in 2.3 tons of mild steel, but I bought oil so as not to raise the temperature, but when I opened 30 pieces, the super steel could not drill out hole. I think that the life is too short. Even made in China it will not break in dozens of holes.
Drilling of stainless steel plate

I purchased thought that it would last long because the price was high, but my teeth flew when I opened 4 stainless steel plates (3 mm thick). I wonder if my arm is bad! I immediately purchased other maker items and continued the work, but I opened eight there, but it was fine.
