ZWEIMENTOOL SNMG series carbide inserts provide exceptional stability and cost efficiency for heavy roughing and general turning applications. These square-shaped negative rake inserts offer 8 cutting edges and are available with multiple advanced coatings to maximize tool life across various materials.
* 8 cutting edges per insert - Industry-leading economy
* Negative rake geometry - Superior edge strength for interrupted cuts
* Multiple coating options - Optimized for different material groups
* Precision-ground surfaces - Ensuring consistent performance (±0.005mm)
* Wide range of nose radii - From 0.4mm to 1.6mm
