UC5115 Grade Technology
The UC5115 grade features a high-toughness carbide substrate paired with a thick Alumina CVD coating. This provides a balance of impact resistance and hardness, making it ideal for stable turning as well as light interrupted cuts in cast iron components.
TNMG Chipbreaker
Designed for CNC machining, the TNMG geometry provides double-sided versatility with 6 cutting edges. The internal chipbreaker is optimized for the short, powdery chips of cast iron, preventing heat buildup and ensuring excellent surface quality on finished parts.
