Drilling of susu 304, sus 316 L
From Japan
On 2017-07-16 07:04:25
Sus304 can be used with confidence. Cospa is nice. Sus 316L has poor blade holding. The defect of the blade leads to defective products, so if the cospa is good, I would like a good one to hold. Especially in products which are hardened by the plasma of thick material, the blade holding is particularly bad.

Although it used, it was able to be used without any problem. The price is reasonable and satisfying.

Drilling in stainless steel
From Japan

Kobelco's drill that he loved for ten years can not be finished, I bought this one which was good for review. However, the sharpness became suspicious from the area where the third hole was opened, and in the fourth hole, the fifth hole, it became almost the same as Kobelco used for 10 years. Is it because it is manufactured abroad (made in Singapore)? It's the worst. I will not buy it anymore.

I got a golden TiN coat by catching it at the exit but it was crispy and I could not catch the exit.
