Make a hole on the corner pipe of 2.3t.

I purchased for 48 holes in mild steel 2.3t material, the temperature had dipped the oil so that it does not rise, where the 30 drilled, super steel is no longer possible drilling off. I think that life is too short. It does not break even in about opened dozens hole made in China.

Drilling in aluminum panels
From Japan
On 2015-11-27 17:01:22
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.

From Japan

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.

Drilling work of steel sheet
From Japan

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.
