The case is strong and comfortable. My ex-husband has two Dewalt drill presses, but he never bought bits and only collected a few from who knows where. Or maybe he bought some. He tends to put things where he left them. He lost his hammers. How do you even lose a hammer. Not to mention hammers. I bought them to finally get some work done before he runs away with drill bits he can barely use. It's nice to have a full range of bit sizes in one place. And know what size I use. I know they will work with any brand I substitute Divorce Dewalts for.
