Everyone should own this set because with it you can drill holes accurate to
1⁄64". That’s nice because many times we’ve needed to drill a hole slightly larger or smaller than we could with my more common fractional bits (1⁄8", 1⁄4", etc.). These bits are made of carbon steel, which doesn’t maintain a sharp edge as long as high-speed steel, but they’ll drill a lot of holes before we’ll even have to think about replacing them.
And the titanium-nitride coating helps reduce heat build-up, which should extend their life.
