There are so many different brands, styles, geometries, profiles, coatings, ect. with carbide inserts that it's just a matter of finding the one that works for your setup. With the small diameters we're turning working with gun barrels most manual lathes wouldn't even have the rpm capabilities to run at the recommended speeds that the carbide mfg suggests. That doesn't mean they won't work, but some definitely work better than others when the speeds are slower than recommended.
