BEYOND WC20-3D-SD17-WC03
Precision 3D Indexable U-Drill | 17mm Industrial CNC Tooling
High-Efficiency 17mm Indexable Holemaking
The BEYOND WC20-3D-SD17-WC03 is a professional-grade indexable insert drill engineered for rapid material removal in heavy-duty CNC machining. This model features a 20mm shank (compact for smaller tool holders) and a 17mm cutting diameter with a 3D depth ratio. Optimized for high-speed internal cooling drilling, it provides exceptional stability and efficient chip evacuation.
Model Code Specification
Technical Data & Units Comparison
| Feature | Metric Model (mm) | Imperial Equivalent (Inch) |
|---|---|---|
| Cutting Diameter (SD) | 17.0 mm | 0.669" |

Material Integrity & Optimized Spiral Flutes
Body Material: Crafted from high-performance quenched alloy steel (20CrMnTi), this WC03 insert holder is built to withstand extreme vibration. The surface is nickel-plated to prevent corrosion and reduce friction during chip evacuation.
Spiral Flute Design: Features an optimized spiral flute for smoother chip discharge, crucial for 17mm precision drilling where chip clogging can lead to tool breakage.
Recommended Cutting Parameters
Optimize your CNC lathe performance with these baseline settings:
- Cutting Speed (Vc): 130 - 230 m/min (Depending on material hardness).
- Feed Rate (f): 0.05 - 0.12 mm/rev.
- Rotation Speed (N): $$N = \frac{Vc \times 1000}{\pi \times 17}$$
- Coolant: Internal high-pressure coolant is required for maximum tool life.
Why Choose WC Trigon Inserts?
- Uses WCMX / WCMT inserts with 3 usable cutting edges.
- More economical than square (SP) inserts for small diameters.
- Excellent performance in low-to-medium carbon steels.
- Hole tolerance is slightly broader than solid carbide drills.
- Not recommended for machines with low spindle RPM at 17mm.

Frequently Asked Questions
Q: What is the difference between WC20 and WC25 shanks?
A: WC20 signifies a 20mm shank diameter, while WC25 is 25mm. Ensure your tool holder matches the 20mm shank of this model.
Q: Can I use SP inserts in this drill?
A: No, this body is specifically designed for WC (Trigon) style inserts size 03.
Q: Is the coolant pipe included?
A: The drill body has internal channels. Standard coolant connectors for your machine will be needed.
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.
