I made the mistake of buying sets of Chinese zero-flute countersinks at first. Then I bought that set of MA Ford's after all the frustration I got from the cheap zero-flutes. Haven't looked back since. Later I lucked out on a big ole 1-1/4" single flute MA Ford countersink I found on ebay for a really good price. It will happily eat through almost anything.
