DNMG150608-MA UE6020
High-Volume Steel Mastery | 6.35mm Thick Stability | MA Medium-Roughing Geometry
Engineered for Maximum Metal Removal Rate (MRR)
UE6020 Grade (Advanced CVD Coating): The UE6020 is Mitsubishi’s premier CVD grade for steel. It features a thick, multi-layered Al2O3 and TiCN coating that provides a superior heat shield. This allows for high-speed machining of Carbon Steel and Alloy Steels without the edge softening or cratering that limits PVD inserts.
MA Chipbreaker (The Multi-Purpose Standard): The MA geometry is designed for medium-range cutting. Its specialized rake angle and chip-pocket width ensure excellent chip breaking even in ductile "stringy" steels. This chipbreaker reduces cutting pressure, preventing vibration on longer workpieces.
06 Thickness & 0.8mm Radius: With a **6.35mm thickness**, this insert has the structural mass to handle heavy depths of cut. The **0.8mm (1/32") radius** provides a robust cutting edge that resists chipping during interrupted cuts while producing industrial-grade surface finishes.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness (S) | Radius (RE) |
|---|---|---|---|---|
| Metric | DNMG150608-MA | 12.70 mm | 6.35 mm | 0.80 mm |
| Imperial | DNMG442-MA | 1/2" | 1/4" | 0.0315" (1/32") |
Recommended Cutting Parameters
*Optimized for steel turning. Use high-pressure coolant to maximize the life of the CVD coating.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Low Carbon Steel (1018) | 200 - 400 m/min | 0.15 - 0.45 mm/r | 1.00 - 4.50 mm |
| Alloy Steel (4140/4340) | 150 - 320 m/min | 0.15 - 0.40 mm/r | 1.00 - 4.00 mm |

UE6020 (The Tough Choice): Best for general-purpose turning in workshops where various steel grades are used. It handles slight interruptions and less-than-perfect setups much better than harder grades.
MC6015 (The High-Speed Expert): Use MC6015 for high-speed continuous finishing in stable setups. For rougher or unpredictable conditions, stick with the reliability of UE6020.

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.
