DNMG Turning Insert, 55° Rhombic, Grade T8430

Elevate your precision steel machining with the fifty-five-degree rhomboid, double-sided negative turning insert from Dormer Pramet®. The ISO-tolerance class-M accuracy ensures unparalleled precision, while the FM chip-breaker with rounded cutting edges sets it apart, offering superior chip control for fine to medium steel machining.

Features and Benefits
• Medium-wide negative T-land enhances cutting-edge strength for versatile machining
• 3-D chip-breaker with protruded groove profile expands chip-breaking limits and provides variations in feed and depth of cut
• Narrow chip groove increases productivity by generating smaller, more manageable chips
• WC-Co substrate, submicron-grained, delivers high hardness, abrasive wear resistance, and comb crack resistance
• PVD coating enhances thermal cracking resistance amid cutting temperature fluctuations
• Multi-layered PVD coating with thick TiN coating for crater wear resistance, hard AlTiN layer for flank wear resistance
• Unique Titanium-Boron-Nitride (TiBN) top layer reduces build-up edge and improves performance

Typical Applications
• Steel
• Automotive
• Machinery applications
