Compared with domestic production as well, the burning is quick. Even though it is cheap, the number of sharpening is high and the price is not suitable. I used to use the stain for drilling unavoidably, but I can use it only once
Drilling to steel materials

It was good at a very reasonable price. However, it breaks more than expensive maker items
I feel easy but I think that it is a consumable part, so it is enough.

Especially not possible, it is used normally. I hope the price is lower.
