No complaints, I recommend to buy.

Its pros: Convenient in drilling holes - from the initial to the largest possible - the diameter of this drill. Its cons: The properties of the metal of this drill are rather weak. It dulls quickly. Poor hardening of the metal.

I am delighted, the product is really worthy.

Some pros: The very idea of ​​making such drills is excellent, there were no such drills before. Different cons: I came across a drill with a poorly sharpened tip, punching is necessary, and this is not possible on thin metal.
