DNMG 110404E-NM INSERT GRADE T8430

Revolutionise your machining precision with the double-sided negative turning insert from Dormer Pramet®. Ideal for fine to heavy machining of steels and stainless steels, the fifty-five-degree rhomboid design and ISO-tolerance class-M accuracy ensure that this insert excels in diverse applications.

Features and Benefits
• Medium-wide positive T-land for improved cutting-edge strength, enabling versatile machining with lower cutting forces
• 3-D chip-breaker ensures precise chip-breaking control across a wide range of feeds and depths of cut
• Medium-width chip groove reduces cutting resistance and vibration, enhancing overall machining performance
• Deep chip groove reduces cutting forces and vibration for smoother machining
• Raised chip-breaker back wall height forces tighter chip curls, improving chip-breaking for tough materials with lower feeds
• Highly positive geometry significantly reduces cutting forces and machining load, enabling smooth turning with minimal vibration
• WC-Co-based substrate, submicron-grained, provides high hardness, abrasive wear resistance, and resistance against comb cracks
• PVD coating enhances thermal cracking resistance and performance in operations with cutting temperature fluctuations
• Multi-layered PVD coating with thick TiN for crater wear resistance and hard AlTiN layer for flank wear resistance
• Unique Titanium-Boron-Nitride (TiBN) top layer reduces build-up edge and improves overall performance
• New coating generation ensures increased durability and performance, making it the most versatile grade for general turning and heavy roughing, even in challenging conditions

Typical Applications
