DNMG110404-MA UE6110
High-Velocity Steel Turning | UE6110 CVD Grade | MA Precision Geometry
Engineered for High-Cycle Efficiency
UE6110 Grade (High-Temp CVD Coating): The UE6110 is Mitsubishi’s premium grade for high-speed continuous turning of steel. It features an ultra-thick $Al_2O_3$ (Aluminum Oxide) coating layer that provides world-class thermal insulation. This allows the tool to maintain a sharp edge even at surface speeds exceeding 300 m/min, specifically in Carbon Steel and Alloy Steels.
MA Chipbreaker (Multi-Application Precision): The MA geometry is the versatile standard for medium-to-finishing cuts. It features a specialized rake face that stabilizes chip flow at high velocities. This design effectively breaks chips even in low-carbon "gummy" steels, preventing surface marring and tangled nests.
0.4mm Radius (The Finishing Detail): The "04" (1/64") radius is the choice for precision. It generates lower radial forces than larger radii, making it ideal for maintaining tight tolerances on slender parts and achieving a high-definition surface finish.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DNMG110404-MA | 9.525 mm | 4.76 mm | 0.40 mm |
| Imperial | DNMG331-MA | 3/8" | 3/16" | 0.0157" (1/64") |
Recommended Machining Parameters
*UE6110 thrives at higher speeds. Avoid using at very low RPM to prevent built-up edge.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon Steel (1045/S45C) | 250 - 450 m/min | 0.08 - 0.25 mm/r | 0.30 - 2.50 mm |
| Alloy Steel (4140/SCM440) | 200 - 380 m/min | 0.08 - 0.20 mm/r | 0.30 - 2.00 mm |
Pro-Tip: UE6110 vs. UE6020
UE6110 (Speed Specialist): The absolute best choice for stable, high-speed continuous turning. It provides 30-50% longer tool life in clean steels compared to general grades.
UE6020 (The Generalist): Choose UE6020 if you have interrupted cuts, vibration, or unstable setups. UE6110 is harder but more brittle; it thrives on speed and stability.

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.
