Pramet CCMT 060204E-UR INSERT GRADE T8430

This single-sided, 80° rhombic turning insert is the pinnacle of precision and versatility. The seven-degree clearance provides strength and adaptability, while the T8430 grade, PVD-coated fine-grained WC-Co carbide cuts within ISO range P20-P40, excelling in fine to heavy machining of steels.

Features and Benefits

• The narrow negative T-land, ensuring cutting-edge strength under common working conditions and ensures smooth machining
• 3-D chip-breaker ensures effective chip-breaking control across a wide range of feeds and depths, enhancing machining versatility
• Wide chip groove enhances chip control, improving evacuation in the machining of tough materials
• WC-Co-based substrate, submicron-grained, offers high hardness, abrasive wear resistance, and comb crack resistance
• PVD coating enhances resistance to thermal cracking and performs well in operations with fluctuating cutting temperatures
• Multi-layered PVD coating features a thick TiN layer for crater wear resistance and a hard AlTiN layer for flank wear resistance
• Unique Titanium-Boron-Nitride (TiBN) top layer reduces build-up edge, enhancing overall performance

Typical Applications

• Steel machining
