I leave 3 stars because the product is a good tool for this price range. But the description shows it as SAE first, but it should show as metric first as it is a metric size. For example, a 1 inch saw is not 1 inch (about 29mm). It is 29mm (about 1 inch). So if you are looking for SAE, look elsewhere. If you want metric these are good saws. I can still use them so I don't have to mess around with returns.
