Capt'n, they are great tool holders and bits, but not for you. The carbide puts to much strain on a small lathe. It needs twice the surface speed and a lot deeper cut than HSS tools. IE lots of Horse Power. It also has a second issue in that the carbide is very brittle. One screwup setting the feed and speed and you have carbide flying. At $5 a pop or close for good carbide bits, it can be a very expensive learning process. Having gone down this path, I highly recommend HSS bits that you grind to shape yourself. Just grind the ends to the general shapes of the chart, and for $5 to $10, you have the full range and if you dull a bit, you can re-sharpen it.
