Nikcole Mini System

I'm with Greg on these inserts as well as carbide inserts in general. They are ideal for running a larger number of parts, but not economical or practical for the home machinist. In addition, they are easily damaged by a less experienced operator. High speed steel is more versatile, economical and forgiving than carbide in the home shop. That said, I do use carbide. I have a selection of carbide end mills, a carbide face mill for my mill and a set of insert turning tools for the lathe that I use for roughing. The turning tools are not very useful with Hardinge because it lacks the power required to use them effectively, all it takes is one stall and the insert is toast.
