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.
