Recommended Cutting Parameters
Optimize your CNC machining with these reference values for 36.5mm U-Drills:
- Cutting Speed (Vc): 110 - 180 m/min (Material dependent).
- Feed Rate (f): 0.05 - 0.12 mm/rev.
- Coolant: High-pressure internal cooling is mandatory for 5D depth to clear chips effectively.
Material Excellence & Slot Design
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—the primary cause of tool breakage in deep hole drilling. This WC06 insert holder is nickel-plated for superior corrosion resistance and surface hardness.
WC Type U-Drill: Pros & Cons
- Uses WCMX/WCMT inserts with 4 cutting edges (Highly cost-effective).
- Better stability on uneven entry surfaces compared to SP drills.
- Superior chip breaking performance on carbon steel.
- Higher torque requirements than SP series.
- Strictly requires precise spindle alignment for 5D depths.
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 and precise spindle alignment to ensure straightness and tool longevity.
