DCMT 11T308E-FM INSERT GRADE T8430

The single-sided 55° rhombic turning insert from Dormer Pramet° is a cutting-edge solution for fine to medium machining in steels and stainless steels. Designed to ensure optimal chip control, reduced cutting forces, and superior surface finishes, the T8430 grade and PVD coating provides durability and wear resistance.

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
• Stainless steel
