I tried to make a hole of tail lamp of 130 mm at the lowest speed with a ball plate in a 0.8 mm scaled stainless steel, but rather than opening a hole, the blade gradually wears away without scratching.
Although it was expensive, it is very abandon.
Even if I think to buy a blade, it is too expensive 1890 yen only with a blade.
I could not turn back because I opened the center hole in the material.
I want a blades that can cut properly.
