I purchase this set so I wouldn't have to search my home for different types of tips. However, it came with two flaws. First off, the tips are loosely placed in their spaces. This means if you the set down two hard they will come loose and fall everywhere when you open it. Secondly, I needed to drill into the masonary block using the tip from the set. After, 10 minutes of drilling I managed to kill two drills with only 1 1/2 holes created. I changed out the bit with one if my trusted bits and did the job in a fraction of the time. Not sure if I will be buying anymore products from Vevor.
