It is less than garbage. Before opening the hole, the center drill broke, three chips flew away wasting the material.
Drilling of 32 mm iron plate

I penetrated 32 mm iron plate in two places. I do not use any more, but I can still use it. The hole saw was also 65 mm and it took cutting time. The chips themselves are weaker than those made in Japan.
I drilled 18 holes of copper perforated board thickness 10 mm - 18 mm.

I attempted to drill into SUS 304 t 1.5, but most of the blades were missing with the first one, and the work did not end. I do not know because I have not tried iron pipes, but I would like to refrain from using it for SUS.

If it is a thin stainless steel plate it can be used without problems. It was possible to use it for the thickness of 1.2 mm stainless steel hood.
