WNMG Turning Insert, 80° Trigon, Grade T8430

Enhance machining efficiency with the double-sided negative turning insert from Dormer Pramet®. Designed for fine to heavy machining of steels and stainless steels, the eighty-degree trigon design, coupled with ISO-tolerance class-M accuracy, ensures precision in a diverse range of applications.

Features and Benefits
• 3-D chip-breaker ensures precise chip-breaking control across a wide range of feeds and depths of cut
• Wide chip groove enhances chip control for improved evacuation when machining tough materials
• Raised chip-breaker back wall height forces tighter chip curls, improving chip-breaking for tough materials at lower feeds
• Neutral geometry increases impact resistance, enabling machining with heavier feed and higher depth of cut
• WC-Co-based substrate, submicron-grained, offers 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 optimised for increased productivity and durability, with a thick TiN coating 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
• Steel
• Stainless steel
