TNMG Negative Inserts for Flexible Turning Applications
JetEdge TNMG carbide turning inserts use a negative, double-sided 60° triangular format. The geometry provides multiple cutting edges and flexible approach directions for general turning, facing and selected roughing applications.
Selected configurations are available for steel, stainless steel and cast iron. Final selection must be based on the complete insert designation and actual cutting condition.
