It is written as if it corresponds to tool steel, SUS in item description, but in the latest blade catalog of the manufacturer this product is disabled for both tool steel and SUS. I think that it is better to correct it because it is necessary for people who use SUS or tool steel to purchase them incorrectly. By the way, I noticed that for the purpose of cutting SUS, I bought a bimetallic one.
I missed the manufacturer of the blade I used before, but purchased this product for the time being, when I used a 1.6 mm iron plate with a jigsaw, the blade disappeared 2 to 3 times. I also asked this manufacturer, but the specification for 1.6 mm is correct. It was disappointing because it was able to be used without trouble by SS and SUS at the previous manufacturer.
