CCGT 120408ER-SI INSERT GRADE T8430

Elevate precision in fine to medium machining of steel and stainless steel with the single-sided 80° rhombic turning insert. Available in both left and right-handed variants, the PVD-coated fine-grained WC-Co carbide cuts within ISO ranges P20 - P40 and M20 - M35 for smooth and efficient turning operations.

Features and Benefits
• Smooth machining facilitated by rounded edges, omitting T-land, with light feed and shallow depths of cut, ensuring ample edge strength while mitigating work-hardening risks
• 3-D chip-breaker guarantees effective chip control across a broad spectrum of feeds and depths, to enhance performance
• Wide chip groove enhances chip control in challenging materials, promoting improved chip evacuation during machining
• WC-Co-based substrate, submicron-grained, delivers superior hardness, abrasive wear resistance, and resistance against comb cracks
• PVD coating enhances resistance to thermal cracking, ensuring optimal performance in operations with varying 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 and enhances overall performance

Typical Applications
• Steels
• Stainless steel
