WNMG080408-SM 1115 CNC Turning Insert for Steel
WNMG080408-SM 1115 CNC Turning Insert for Steel, CVD/PVD Coated for Steel/Stainless Steel CNC Turning
WNMG080408-SM 1115 is a high-performance negative triangular turning insert designed for semi-finishing and finishing operations on steel. With the advanced 1115 grade, this insert delivers exceptional wear resistance, thermal stability, and long tool life under medium-to-high cutting speeds. It is ideal for CNC turning centers, automated production environments, and precision machining of steel components.
Key Features & Benefits
- Optimized for Steel (P-group materials)
Grade 1115 provides superior wear resistance and excels in high-speed continuous cutting.
- SM Chipbreaker for Excellent Chip Control
The SM geometry ensures smooth chip evacuation, reducing built-up edge and improving surface quality.
- WNMG Negative Geometry
Double-sided insert increases tool economy and suits a wide range of turning operations.
- High-temperature Oxidation-resistant Coating
Maintains hardness and stability at high cutting speeds, minimizing flank wear and chipping.
- Perfect for Continuous and Light Interrupted Cutting
Suitable for turning shafts, flanges, steel pipes, and precision external & facing cuts.
