I think that it is a good product for the ordinary concrete. However, if you crush a recent high-strength concrete or PC board, it is also quick to decrease, and if it is polished with a grinder, the tip will be missing. When polishing, it may be better to shave little by little so as not to bake in.
The sense of biting into concrete was good. Although it has not verified about durability, the tip was not rounded even after the whole day's work. Considering price and performance it is a candidate for continued purchase.
