Product Overview: High-Efficiency Solution for Steel Machining
CNMG190612-PM 4325 is an imported carbide turning insert from (Sweden), specifically designed for steel machining. Integrating advanced CVD coating technology and optimized chip breaker structure, it achieves the perfect balance between long tool life and high stability in semi-finishing to roughing applications. As an ISO standard negative rake insert, its model breakdown is as follows: CNMG denotes 80° diamond insert (C), 0° clearance angle (N), medium precision (M), with hole and chip breaker (G); 190612 represents 19mm insert size, 6.35mm thickness, 1.2mm nose radius; PM stands for semi-finishing-roughing chip breaker; and grade 4325 symbolizes the superior performance combination of CVD coated carbide.

Performance Advantages: Three Technical Breakthroughs
Super Wear-Resistant Coating System: Adopting Kyocera's CVD Black & Gold dual-color technology, the surface high-hardness TiC film inhibits flank wear, while the inner highly oriented Al₂O₃ film effectively resists crater wear. Tool life is extended by 1.4x compared to similar products in S43C steel machining.
Innovative PM Chip Breaker Design: Special curved groove structure enables uniform chip deformation, achieving 4x life extension in 45# steel nut machining and reducing chip clogging rate by over 90%.
High-Toughness Substrate Formula: Gradient carbide substrate design provides better chipping resistance than traditional P25 grade, completing 300 workpieces per cutting edge without chipping in 20CrMoH automotive parts heavy interrupted machining.
Application Scenarios & Industry Value
Core Application Fields: Automotive components (steering knuckles, gears), construction machinery (bolts, nuts), general machinery (bearing rings) and other steel machining scenarios, especially suitable for semi-finishing to roughing of 45# steel, 20CrMoH, 42CrMoH materials.
In practical applications, the insert empowers production through the following value points:
Cost Optimization: Extended tool life reduces tool change frequency, with 150-300 workpieces per cutting edge, lowering tooling costs by 40%.
Efficiency Improvement: Supports high cutting speed of Vc=200-270m/min, increasing metal removal rate by 35% compared to traditional inserts.
Quality Stability: Improved uniform nose wear ensures stable surface roughness Ra ≤1.6μm, reducing subsequent grinding processes.
