I found it very safe for finish accuracy, how to dig into, durability and I noticed it. It is a good item. However, when the plastic case is delicate and opened and closed roughly, it seems that the lid is broken, I use mind and because it is hard to see the mold with the size letters, I traced the top with magic and made it easy to see. Since I added some sizes, I hope to find a good drill storage case.
Since the Nazi drill has been used for many years, although it is reliable, the price is high. It is a difficult technique to arrange all items at the decimal place first. Please make it a little cheaper
At first I tried to purchase only the required diameter, but half of the ten sets saw the necessary drill diameter soon, so I bought a set of 10 with case. Since the set items are cheap, it was good as a result. Since the blade is HSS, you can comfortably drill up to soft iron.
