For a really good full set of metric taps, find an older Craftsman set on eBay. With Amercan made taps. These are far superior to any of the Hanson taps, (that are rebranded by many companies, and are now made in China) and the whole used set won't cost much. New Craftsman taps, (along with many other products of their's), are now all Chicom garbage. If you break one of the older Craftsman taps, replace it with a Greenlee from McMaster Carr.
