Recommended Cutting Parameters
Optimize your CNC tooling performance with these verified parameters:
- Cutting Speed (Vc): 100 - 180 m/min (Material dependent).
- Feed Rate (f): 0.05 - 0.12 mm/rev (Standard carbon steels).
- Revolution (n): Approx. 1400 - 2500 RPM for 22.5mm diameter.
- Coolant: High-pressure internal coolant is mandatory for 5D depth to ensure chip clearance.
Premium Material & Flute Geometry
This WC04 insert holder is manufactured from high-grade alloy steel with specialized heat treatment for anti-vibration performance. The spiral flute geometry is wide-designed for "forced" chip evacuation. This prevents chip-packing—the primary cause of tool failure in 22.5mm deep-hole drilling. The nickel-plated surface ensures superior corrosion resistance and reduces friction during the machining process.
WC Series U-Drill: Pros & Cons
- Uses WCMT / WCMX inserts with 3 cutting edges for cost-efficiency.
- Superior stability when entering uneven or curved workpieces.
- Excellent chip breaking on low-carbon and alloy steels.
- Higher machine torque required compared to SP series.
- Requires strict spindle alignment for 5D deep-hole precision.
Tool Tip: Selecting Drill Depth (2D to 5D)
The L/D ratio is critical for CNC machining success:
- 2D/3D: Highest rigidity. Best for general shallow holes and high-feed applications.
- 4D: A balanced universal standard for most CNC workshops.
- 5D (This Model): Specialized deep-hole drill bit. Capable of reaching deep cavities but must be used with adequate internal coolant pressure (minimum 20 bar) 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.
