Fully Ground Precision | Miracle PVD Technology | SN Super-Fine Geometry
The Swiss-Type Precision Benchmark
VP15TF Grade (Miracle PVD Performance): The VP15TF grade is the pinnacle of universal PVD coatings. The Miracle Coating (Al-Ti-N) provides an extreme thermal barrier. Because the coating is thin and uniform, it preserves the high-precision ground edge of the DCET series, preventing the microscopic rounding that causes dimensional drift in small parts.
SN Chipbreaker (The Low-Force Finisher): The SN geometry is engineered for "Super-light" cutting. It features a high-rake angle that reduces radial cutting force to the absolute minimum. This is vital when machining slender shafts or small-diameter bores where tool pressure would otherwise cause part deflection or chatter.
0.2mm (0.0078") Radius & Ground Accuracy: The 02 radius is designed for high-precision profiles. Being an E-Class (Ground) insert, the tolerances on the I.C. and thickness are significantly tighter than standard M-class inserts, ensuring your "first part" is as accurate as your "last part."
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DCET070202L-SN | 6.35 mm | 2.38 mm | 0.20 mm |
| Imperial | DCET21.50.5L-SN | 1/4" | 3/32" | 0.0078" |
Precision Machining Parameters
*The 0.2mm radius requires low feeds to maintain edge integrity. Ensure high RPM for small diameters.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Free-Cutting Steel | 120 - 220 m/min | 0.02 - 0.08 mm/r | 0.05 - 1.00 mm |
| Stainless (SUS303/304) | 80 - 150 m/min | 0.02 - 0.06 mm/r | 0.03 - 0.80 mm |
Compatible Left-Hand Tooling
Specifically designed for SDJC or SDUC Left-Hand (L) holders:
Shop SDJCL HoldersPro-Tip: DCET Ground vs. DCMT Molded
DCET (Precision Ground): Use for parts with tolerances under 0.02mm. The indexing accuracy is vastly superior, meaning less "re-zeroing" after tool changes.
DCMT (M-Class Molded): Use for general turning where cost-per-edge is the priority and tolerances are more relaxed.

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.
