Advanced Edge Preparation Technologies

Our small turning tools employ advanced passivation technology.The cutting edges are sharp and highly wear-resistant, effectively

reducing cutting resistance, minimizing the formation of built-up edges, and enhancing the surface finish of the machined parts.
