For drilling a 25 mm thick aluminum case I bought it. The sharpness is also good, and the carbide blade is still good.

It is very easy to drill the work. I do not know the durability yet so I made it "somewhat satisfied".

A2017 I used it to make holes 8 mm thick. Since 8 mm is impossible from one side, it is processed from both sides. It was easy to open.

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.

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.

Although I have not used it yet, I use the same size. Especially trouble is not found, but the price is high, is not it? At first I used a punch press, but the aluminum panels bent too far. Again, I realized again that Holso was a necessary thing.

I repeatedly drilled aluminum plate (3 mm thick) with electric drill driver, but I am satisfied that it opened smoothly and cleanly. I think that durability is somewhat because it does not have a chipping defect etc at the moment so far.
