I am using it to make holes in steel.

It may be that there is some strength. Whether this is bad is pretty, it breaks. It might be good even if a sticky material is used.

I am dissatisfied with durability which is easy to break compared to other products. Even if you use drilling oil, it tends not to cut. It seems to be suitable for DIY. As a professional tool it is recommended that about 2 millimeters of iron is used.

I think that it is very cheap. It is used in multi-axis drilling machine. It is a feeling I gained.

Although I use only two out of ten, one will shift the center even if using a punch.

As it is still a consumable item, it is nothing more than cheap to use.
Purchase for M4 tapped hole

Because the price is also cheap, I chose to disposable rather than regrinding the tip, but since I do not strike the punch, the tip of the drill is a bit broad, so if you use it as it is with an electric drill, it is not fixed to the position I want to open, so the tip a little more I would like you to be sharp

Although I do not use it much yet, cost performance is good, but durability is not good.

I purchase it every time. Because quality is low price without problems, we are continuing to purchase.
When opening a bolt hole

I bought while worried because the price is quite cheap with other companies, but sharpness was good and easy to use

Because it is 10 pieces, it can be used with confidence even if it breaks. It is cheap and I use it normally.
