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.

Drilling in aluminum panels

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.

The blade of the cutter is solid and it looks very good after processing. Since there are various sizes in future, I will use it.

Because it processed with the keyless chuck, the load was applied and the chuck became useless.

Due to the large hole diameter, there is some shake, but it is cut. I also want to check how much use frequency can be kept.
