1. ISO Standard Dimensions & Geometry (VNMG 130404)
V: 35-degree rhombic (diamond) shape profile. It has a narrow profile, making it the choice for contour profiling, copy turning, and reaching narrow shoulders.
N: Negative insert geometry (0-degree clearance relief angle). It relies on the tool holder's seat angle for clearance, providing top and bottom cutting edges for a total of 4 cutting corners.
M: Precision tolerance class governing thickness and inscribed circle index.
G: Features a central hole and molded chip grooves on both faces for dual-sided clamping.
13: Nominal cutting edge length of 13.8 mm.
04: Insert body thickness measuring exactly 4.76 mm.
04: Corner nose radius of 0.4 mm. This sharp radius lowers cutting forces, minimizes workpiece deflection, and generates a refined, high-quality surface finish.
2. Chipbreaker Geometry (FG)
FG (Finishing Geometry): Features a positive rake profile with a tight chip-former ridge. It is designed to curl and cleanly snap thin metal ribbons during shallow cutting passes. It lowers tool vibration and prevents "bird-nesting" when cutting steel and stainless surfaces.
Taegutec
3. Carbide Grade & Coating Layer (TT5080)
TT5080: A specialized PVD (Physical Vapor Deposition) GoldRush series grade from TaeguTec. It applies a highly adhesive, ultra-smooth AlTiN-TiN multi-layered coating over a tough, submicron carbide substrate matrix.
Target Applications: Engineered for high-temperature superalloys, titanium, and heat-resistant stainless steels.
Properties: High thermal stability and excellent resistance to notch wear, depth-of-cut line chipping, and built-up edge (BUE) formation .
