Recommended Cutting Parameters
Optimize your CNC metal drilling performance with these reference values for 31.5mm drills:
- Cutting Speed (Vc): 100 - 180 m/min (Adjust based on material hardness).
- Feed Rate (f): 0.05 - 0.12 mm/rev.
- Coolant Requirement: High-pressure internal coolant is mandatory for 5D depth to ensure effective chip removal and prevent tool overheating.
Material Excellence & Slot Design
This WC06 insert holder is forged from high-strength alloy steel with specialized anti-vibration heat treatment. The spiral flute geometry is wide-designed for "forced" chip evacuation, which prevents chip-packing—the primary cause of tool failure in 31.5mm deep hole drilling. The nickel-plated surface provides excellent corrosion resistance and enhanced tool life in demanding CNC environments.
WC Type U-Drill: Advantages & Considerations
- Uses WCMX / WCMT inserts with 4 cutting edges (Highly 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 precise spindle alignment for 5D deep-hole applications.
Pro-Tip: Choosing Drill Depth (2D to 5D)
The L/D ratio determines stability and application range in CNC tooling:
- 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 allows for deep penetration but requires high-pressure internal coolant 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.
