This is a great way to have a complete set for drilling holes. It is such a random thing to need, but it is something that pops up. I have a few different sizes and some were just plastic so only good for gentle use. This replaces all of them and more. The quality is amazing for home usage. A contractor might even be able to get by if it is just occasional usage. I do think that someone using these regularly might find the more common sizes wear out, but that one or two size could be replaced. These should be pretty interchangeable with other brands. And the case is great to keep everything organized. Vevor is a brand that is affordable, but still makes a decent product. I wouldn't hesitate to get things from them, and so far they have always worked well. This set so far seems to be typical of their decent quality at an affordable price point.
