MZG Turning Inserts System
As a senior industrial tooling expert at MZG Tool Machine Company, I am proud to present a detailed introduction to our comprehensive portfolio of Turning Inserts. These inserts are the fundamental element of all modern turning operations, representing the pinnacle of material science and geometric design. Each insert in our catalog is the result of rigorous development, engineered to provide the optimal combination of toughness, wear resistance, and cutting-edge geometry for its intended application.
Unmatched Strength & Economy
Negative angle double-sided inserts deliver immense strength and exceptional economic value through double-sided design, effectively doubling cutting edges per insert and drastically reducing cost-per-edge.
Superior Precision & Surface Finish
Positive angle single-sided inserts produce exceptional surface finishes with low cutting forces, creating sharp cutting edges for clean shearing action and reduced heat generation.
Ultimate Material Versatility
Advanced grade and coating performance with comprehensive range of materials including PCD, CBN, Cermet grades, and coated carbide for every material from steel to aluminum.
Product Performance
The performance of our turning inserts is best understood by classifying them into two primary families—Negative and Positive rake inserts—each delivering a distinct set of advantages.
Unmatched Strength & Economy – Negative Angle (Double-Sided) Inserts: The performance of our Negative angle inserts (CN.., DN.., KN.., RN.., SN.., TN.., VN.., WN..) is defined by their immense strength and exceptional economic value. Featuring a 0° clearance angle, these inserts are double-sided, effectively doubling the number of available cutting edges per insert and drastically reducing the cost-per-edge. This design creates an incredibly strong and robust cutting edge, making them the undisputed choice for heavy cutting roughing and high-volume material removal.
Superior Precision & Surface Finish – Positive Angle (Single-Sided) Inserts: The performance of our Positive angle inserts (CC.., DC.., RC.., WB.., TB.., TC.., TP.., VB.., VC..) is characterized by their ability to produce exceptional surface finishes and maintain tight dimensional tolerances with low cutting forces. These single-sided inserts feature a positive clearance angle, which creates a much sharper cutting edge.
Ultimate Material Versatility – Advanced Grade & Coating Performance: Our portfolio includes a comprehensive range of advanced materials: PCD (Polycrystalline Diamond) for high-speed finishing of non-ferrous alloys, CBN (Cubic Boron Nitride) for hardened steels (HRC46-60+), Cermet Grades (ZN60, ZN90) for high-speed finishing, and Coated Carbide Grades with CVD and PVD coating technologies.
Key Performance Indicators
- Double-Sided Design: Negative inserts provide twice the cutting edges for exceptional economy
- Superior Strength: 0° clearance angle creates incredibly strong cutting edges for heavy roughing
- Precision Finishing: Positive inserts deliver exceptional surface finishes with low cutting forces
- Advanced Materials: PCD, CBN, Cermet, and coated carbide grades for all applications
- ISO Compatibility: Global standard geometries ensure predictable performance

Technical Parameters
ISO Geometry & Rake Angle
Insert shapes include S (Square 90°), T (Triangular 60°), C (Rhombic 80°), D (Rhombic 55°), V (Rhombic 35°), W (Trigon 80°), and R (Round). Negative inserts have 0° side clearance for double-sided use, while positive inserts have built-in clearance angles for sharper cutting edges.
Insert Grade & Coating
Advanced materials include PCD for non-ferrous alloys, CBN for hardened steels (HRC46-60+), Cermet grades (ZN60, ZN90) for high-speed finishing, and coated carbide grades with CVD and PVD coating technologies for material-specific applications.
Chipbreaker Geometry
Molded chipbreaker geometries range from sharp geometries for light-finishing cuts producing fine chips, to very strong, open geometries for breaking heavy, thick chips during deep roughing cuts. Critical parameter for optimal chip control and surface finish.
