I have spent some time with these bits, now, and am very impressed. They aren’t the cheapest to buy, but they will last far longer than the average purchase. Overall, they save money and stay super sharp. These two sets were bought at separate times, but they are slightly different. One holds a set that is for a multitude of materials, the other, for metal. I have tried these on wood, plastic and metal, and found that they are proficient.
They are each hardened and have been used many times. There isn’t much more to say about them, except they are worth the money and will serve you well.
