WNMG 080412E-FM Insert Grade T8430

This double-sided, negative 80° trigon turning insert is a top choice for precise and versatile machining. Crafted from T8430 grade, a PVD-coated fine-grained WC-Co carbide within ISO ranges P20-P40 and M20-M35, it excels in fine to medium machining of steels and stainless steel.

Features and Benefits
• The medium-wide, positive T-land ensures 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
