Recommended Cutting Parameters
Optimize your CNC metal drilling performance with these reference values:
- Cutting Speed (Vc): 110 - 180 m/min (Material dependent).
- Feed Rate (f): 0.07 - 0.15 mm/rev.
- Coolant Requirement: High-pressure internal cooling is mandatory for 5D depth to ensure effective chip evacuation.
Advanced Material & Flute Geometry
Constructed from high-strength alloy steel with specialized anti-vibration quenching, the BEYOND U-Drill offers exceptional durability. The spiral flute geometry is wide-designed for "forced" chip removal, preventing chip-packing during deep hole drilling. Using WC08 carbide inserts, this holder features four cutting edges per insert, making it a highly cost-effective CNC tooling solution.
WC Type U-Drill: Pros & Cons
- 4 cutting edges per insert (Economic).
- Better stability on uneven entry surfaces.
- Widely available WCMX/WCMT insert compatibility.
- Slightly lower feed rates than SP types.
- Higher thrust requirements for large diameters.
Pro-Tip: Choosing Drill Depth (2D to 5D)
The L/D ratio determines stability and application range:
- 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. Requires high-pressure internal coolant and precise spindle alignment to ensure straightness.
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.
