Fully Ground E-Class | Miracle PVD Coating | SN Low-Force Precision
The Ultimate Finishing Solution
VP15TF Grade (Miracle PVD Shield): The VP15TF is a micro-grain carbide substrate enhanced by Mitsubishi’s proprietary Miracle (Al-Ti-N) PVD coating. Because this is a PVD process, the coating thickness is perfectly uniform, ensuring that the fully ground cutting edge of the DCET remains ultra-sharp. It offers high resistance to built-up edge (BUE) and thermal cracking.
SN Chipbreaker (Vibration Control): The SN geometry is a sharp, positive-rake chipbreaker specifically engineered for "super-light" finishing. It reduces the radial cutting force that typically causes part deflection or vibration. It is the preferred geometry for long, slender shafts or finishing deep internal bores.
Fully Ground (E-Class) Precision: Unlike standard M-class inserts (DCMT), every surface of the DCET is precision ground. This results in superior indexing accuracy—when you flip the insert to a new edge, your machine's offset requires minimal adjustment.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DCET11T304R-SN | 9.525 mm | 3.97 mm | 0.40 mm |

Precision Machining Parameters
*The 11T3 size offers high stability. For best results, ensure the depth of cut is within the chipbreaker's effective range.
| Material Group | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Alloy Steel / Tool Steel | 120 - 250 m/min | 0.05 - 0.15 mm/r | 0.10 - 1.50 mm |
| Stainless Steel (304/316) | 90 - 180 m/min | 0.04 - 0.12 mm/r | 0.08 - 1.20 mm |
Pro-Tip: DCET Ground vs. DCMT Molded
DCET (Ground): Best for aerospace or medical parts where tolerances are tighter than +/- 0.01mm. The ground edge significantly reduces "smearing" on stainless steel.
DCMT (Molded): Use for general-purpose roughing and semi-finishing where the accuracy of the insert index is less critical.

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.
