The double-sided negative turning insert from Dormer Pramet features a 55-degree rhomboid design and an ISO-tolerance class-M indexing precision. Crafted from grade T8430 WC-Co carbide, the chip-breaker FM has rounded cutting edges to ensure efficient chip evacuation, preventing tool jamming. This cutting-edge solution optimises machining processes, offering reliability and consistent, high-quality results.
Features and Benefits
Medium-wide negative T-land enhances cutting-edge strength for versatile machining
3-D chip-breaker with protruded groove expands chip-breaking limits, offering varied feed and depth options
WC-Co substrate with submicron-grained structure provides high hardness and wear resistance
PVD coating enhances thermal cracking resistance and performance in fluctuating cutting temperatures
Multi-layered PVD coating with TiN and AlTiN layers ensures durability and resistance to crater and flank wear
Unique Titanium-Boron-Nitride (TiBN) top layer reduces build-up edge and improves overall performance
