I have used HSS tooling on my Sherline lathe for years. I keep seeing 1/4" and 3/8" sets of carbide tools extremely inexpensive albeit from China. I know about Valenite and the other makers but I am interested in the Chinese because they are cheap as am I. I use chip breakers on my MaxiMat7 and they work well. I'm wondering if anyone has experience with these. I have heard somewhere that they have been used disappointedly. Is that a word? I have a friend that uses brazed carbide almost exclusively but he first sharpens them on a diamond wheel. I am happy with HSS but am curious if it is worth testing the $25-$30 tools.
