Recommended Cutting Parameters
Optimize your CNC metal drilling performance with these reference values:
- Cutting Speed (Vc): 110 - 180 m/min (Adjust based on material).
- Feed Rate (f): 0.06 - 0.12 mm/rev.
- Coolant Requirement: Internal High-Pressure Coolant is mandatory for 5D depth to clear chips effectively.
WC Type U-Drill: Pros & Cons
- 4 cutting edges per insert (Cost-effective).
- Better stability on uneven entry surfaces.
- Uses widely available WCMX / WCMT inserts.
- Slightly lower feed rates compared to SP series.
- Requires higher torque for deep hole operations.
Material & Flute Geometry
Constructed from high-strength alloy steel with specialized anti-vibration heat treatment. The spiral flute geometry is wide-designed for "forced" chip evacuation, preventing chip-packing—the primary cause of tool breakage in deep hole drilling. This WC06 insert holder is nickel-plated for superior corrosion resistance and prolonged tool body life.
Pro-Tip: Choosing Drill Depth (2D to 5D)
Selecting the correct L/D ratio is critical for CNC tooling performance:
- 2D/3D: Maximum rigidity. Best for high-speed shallow holes.
- 4D: The universal standard for general purpose machining.
- 5D (This Model): Specialized deep-hole drill. It requires high-pressure internal coolant and precise spindle alignment to ensure straightness and tool longevity.
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.
