Countersink

Yes, this looks different than the countersinks that you are used to, but the results are much better! This tool shears the wood rather than scraping the wood, and the results will make you wish that you had found this tool sooner. Wood Magazine calls this "The best countersink bits I’ve ever seen". Stern - Austria.
