I bought this drill bit set more than a year ago and been happily using them for wood mostly but also metal. The reason why I decided to get these was because I think my time is more important to spend working than sharpening. They stay sharp like a charm. Ive only sharpened the most common sizes that I use a lot once or twice. If u have a nice organized shop where you dont lose small expensive things these are definately worth the investment. They never heat up and cut through wood very very cleanly straight out of the box.
This set offers a nice selection of bit sizes and comes in a convenient carrying case. The bits work well in softer materials but are not recommended for drilling harder metals. I have already broken several bits under "regular usage".
