DNMG150604-MA UE6020
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.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
