CCMT060208-MM VP15TF
Medium-Duty Specialist | Miracle PVD Coating | MM High-Strength Geometry
Toughness Meets Precision
VP15TF Grade (Miracle PVD): Mitsubishi’s legendary PVD grade. The Miracle Coating provides a powerful thermal barrier and superior lubrication. This prevents "galling" and built-up edge when machining Stainless Steel, Alloy Steel, and Cast Iron, significantly extending tool life in interrupted cuts.
MM Chipbreaker (Medium Cutting): The MM geometry is designed for versatile "Medium" applications. It features a reinforced cutting edge that can handle higher feed rates and larger depths of cut than the FM or FV series. It is the perfect balance for semi-roughing and general turning.
0.8mm High-Strength Radius: The 08 (1/32") radius is built for Durability. It provides a much stronger edge than 0.2mm or 0.4mm versions, making it resistant to chipping during heavier loads or when cutting through material "skin."
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CCMT060208-MM | 6.35 mm | 2.38 mm | 0.80 mm |
| Imperial | CCMT21.52-MM | 1/4" | 3/32" | 0.0315" (1/32") |
Recommended Cutting Parameters
*The MM chipbreaker thrives under slightly higher pressure. Avoid extremely light 'whisker' passes to ensure proper chip breaking.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon/Alloy Steel | 120 - 240 m/min | 0.10 - 0.25 mm/r | 0.50 - 2.00 mm |
| Stainless Steel | 80 - 170 m/min | 0.08 - 0.20 mm/r | 0.40 - 1.50 mm |

Shop SCLCR 06 HoldersPro-Tip: MM vs. FM Chipbreaker
MM (Medium): Use for general-purpose turning and when you need to remove material faster. The 0.8mm radius is very strong.
FM (Finishing): Switch to FM with a smaller radius (0.2 or 0.4) if you are doing very light finishing passes or need to reduce tool pressure on delicate parts.

Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
