These are good, I've cut a lot of wood and metal with them (usually on a metal drill) over a few years and they've held up great. The hardest cuts were several 1/2" holes in 2" thick mild steel that kept them intact. There are two of the usual smaller pairs, a spare is useful as they tend to break/dull first. The only thing to note is the slightly odd shape of the Dewalt "Pilot Point" cutting surface. This is useful in most cases, but gives blind holes an unusual final shape, and the very flat cutting surface behind the point makes it difficult to center in existing holes and almost impossible to sharpen.
