The Universal Steel King | MC6025 Nano-Texture | MP Medium Control
The First Choice for General Steel Turning
MC6025 Grade (Nano-Texture CVD Coating): The MC6025 is Mitsubishi's most popular steel turning grade. Using an advanced Al2O3 (Alumina) coating with a refined nano-texture, it provides an incredible barrier against heat and chemical wear. This grade is specifically engineered to handle the "unpredictable" — surviving light interrupted cuts while maintaining high speeds in continuous turning.
MP Chipbreaker (Medium-Positive Geometry): The MP breaker is designed for the modern CNC environment. It features a unique wave-profile land that maintains constant chip control even when the feed rate or depth of cut fluctuates. Its "Positive" rake design reduces cutting resistance, lowering spindle load and extending tool life.
0.8mm (1/32") All-Purpose Radius: The 08 radius is the industry standard for medium turning. It provides a robust cutting edge that resists chipping while delivering the surface finish quality ($Ra$) required for most industrial semi-roughing and finishing specifications.

Recommended Cutting Parameters
*The MC6025 grade handles a wide speed range. Use stable parameters for maximum tool life and consistent chip breaking.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon Steel (1045) | 180 - 350 m/min | 0.15 - 0.45 mm/r | 0.80 - 4.50 mm |
| Alloy Steel (4140) | 150 - 280 m/min | 0.15 - 0.40 mm/r | 0.80 - 3.50 mm |

MC6025 (The Workhorse): Your first choice for general turning. Better toughness for interrupted cuts and vibration resistance.
MC6015 (The Speed Master): Switch to MC6015 for high-speed continuous turning where you need absolute maximum crater wear resistance and productivity.
