Technical Data & Metric/Imperial Comparison
| Feature | Metric Model | Imperial Equivalent |
|---|---|---|
| Cutting Diameter (SD) | 37.0 mm | 1.457" |

Recommended Cutting Parameters
Maximize your WC06 insert holder performance with these settings:
- Cutting Speed (Vc): 110 - 180 m/min (Material dependent).
- Feed Rate (f): 0.06 - 0.14 mm/rev.
- Coolant Strategy: High-pressure internal coolant is mandatory for 4D depth to flush chips effectively and protect the drill body.
Material Excellence & Spiral Flute Design
Constructed from high-strength alloy steel with specialized anti-vibration quenching, this 37mm indexable drill bit offers extreme durability. The wide spiral flute geometry is specifically engineered for "forced" chip removal, preventing chip-packing—the primary cause of tool failure in large diameter drilling. The nickel-plated surface provides excellent corrosion resistance and enhanced tool life.
WC Series U-Drill: Pros & Cons
- Uses WCMX / WCMT inserts with 4 cutting edges (Cost-effective).
- Better stability on uneven or curved entry surfaces compared to SP drills.
- Superior chip breaking performance on carbon and alloy steels.
- Higher torque requirements than SP series drills.
- Requires high-power CNC spindles for 37mm diameters.
Pro-Tip: Choosing Drill Depth (2D to 5D)
The L/D ratio determines stability and application range in CNC metalworking:
- 2D/3D: Maximum rigidity; ideal for shallow holes and high feed rates.
- 4D (This Model): The industrial standard for deep-hole drilling; provides reach without sacrificing stability.
- 5D: Extreme depth; requires very high coolant pressure and precise alignment to prevent tool breakage.
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.
