Thick Cross-Section Stability | CVD UE6020 Grade | MA Precision Control
Rigid Engineering for Steel Mastery
UE6020 Grade (Advanced CVD Coating): The UE6020 is Mitsubishi's benchmark for steel turning. This CVD grade features a multi-layer coating designed to withstand high-speed friction. It excels in Carbon Steel (P20-P30 range) and Alloy Steels, offering a perfect balance between wear resistance and edge toughness for general workshop use.
MA Chipbreaker (Precision Medium Cut): The MA geometry is designed for medium-range machining. Its unique rake surface ensures stable chip breaking even at lower feed rates. This prevents surface scratching from "long chips" and ensures that heat is efficiently transferred into the chip, away from the cutting edge.
06 Thickness (Extra Thermal Mass): The 6.35mm (06) thickness provides more volume than standard 4.76mm inserts. This leads to better heat dissipation and prevents plastic deformation during long, continuous cuts on large diameter parts.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness (S) | Radius (RE) |
|---|---|---|---|---|
| Metric | DNMG150604-MA | 12.70 mm | 6.35 mm | 0.40 mm |
| Imperial | DNMG441-MA | 1/2" | 1/4" | 0.0157" (1/64") |
Recommended Cutting Parameters
*The 06 thickness allows for slightly higher speeds in stable setups. Use coolant for consistent chip control.
| Material Group | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon Steel (S45C) | 180 - 320 m/min | 0.10 - 0.25 mm/r | 0.50 - 3.00 mm |
| Alloy Steel (4140) | 140 - 280 m/min | 0.10 - 0.20 mm/r | 0.50 - 2.50 mm |
Compatible Tool Holders

UE6020 (General Purpose): The most common choice for stable, general turning in mild to medium carbon steels. Excellent for general job shops.
MC6025 (High Edge Toughness): Switch to MC6025 if you are dealing with heavy interrupted cuts or machining rough outer scale. UE6020 is better for continuous turning at higher speeds.
