UE6020 Grade: The All-Rounder
The UE6020 grade is Mitsubishi's premium CVD solution for general steel turning. Unlike specialized high-speed grades, UE6020 features a substrate with improved toughness, making it highly resistant to chipping even in varied cutting conditions. The multi-layer coating ensures excellent protection against plastic deformation and wear.
Positive Chip Control
Featuring a 7° positive rake angle, this indexable turning insert reduces cutting load and prevents workpiece vibration. The precision-engineered chipbreaker ensures reliable chip evacuation across a wide feed range, maintaining surface quality even during finishing passes on alloy steel.
