DCET070202R-SN VP15TF
E-Class Ground Precision | Miracle PVD Coating | SN Ultra-Low Force
High-Accuracy Swiss-Type Performance
VP15TF Grade (Miracle PVD Tech): The VP15TF is Mitsubishi’s premier universal PVD grade. It utilizes a micro-grain carbide substrate coated with Miracle Al-Ti-N. Because the coating is applied via PVD, it is significantly thinner than CVD, allowing the insert to maintain the extreme sharpness of its ground edge—essential for preventing work-hardening in stainless steel and titanium.
SN Chipbreaker (Precision Chip Control): The SN geometry is a sharp, positive-rake breaker designed for light depths of cut (finishing). It creates a "slicing" action that minimizes radial pressure. This prevents the "pushing" of slender parts, ensuring that diameters remain consistent across the entire length of the workpiece.
0.2mm (0.0078") Radius & Ground Accuracy: As an E-Class ground insert, the DCET series offers much tighter tolerances than molded M-class inserts. The 0.2mm radius is perfect for fine profiles and achieves a superior surface finish (Ra) even at low feed rates.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DCET070202R-SN | 6.35 mm | 2.38 mm | 0.20 mm |
| Imperial | DCET21.50.5R-SN | 1/4" | 3/32" | 0.0078" |
Precision Machining Recommendations
*The SN breaker is for finishing only. Do not exceed the maximum depth of cut to avoid edge fracture.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Carbon/Alloy Steel | 120 - 240 m/min | 0.02 - 0.08 mm/r | 0.05 - 1.00 mm |
| Stainless (304/316) | 80 - 160 m/min | 0.02 - 0.06 mm/r | 0.03 - 0.70 mm |

Shop SDJCR HoldersPro-Tip: Ground DCET vs. Molded DCMT
DCET (Ground): Best for parts where tolerance is within 5-10 microns. The ground periphery ensures the insert sits exactly in the same position every tool change.
DCMT (Molded): Choose for general-purpose turning where tolerances are more relaxed and budget is a priority.

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.
