Recommended Cutting Parameters
Achieve peak performance for your 27mm indexable drill bit with these settings:
- Cutting Speed (Vc): 100 - 180 m/min (Depending on material hardness).
- Feed Rate (f): 0.05 - 0.12 mm/rev.
- Coolant: High-pressure internal coolant is mandatory for 5D depth to clear chips and protect the WC05 insert holder.
Material Science & Spiral Flute Geometry
Constructed from premium alloy steel with specialized anti-vibration quenching, this tool body ensures maximum rigidity. The wide spiral flute geometry is designed for "forced" chip removal, preventing chip-packing—the primary cause of tool failure in 27mm deep hole drilling. This WC05 insert holder is nickel-plated for superior corrosion resistance and a longer lifespan in harsh CNC tooling environments.
WC Series U-Drill: Pros & Cons
- Uses WCMX/WCMT inserts with 4 cutting edges (Highly cost-effective).
- Exceptional stability on irregular or curved entry surfaces.
- Superior chip breaking on low-carbon and alloy steels.
- Higher torque requirements compared to SP series drills.
- Sensitive to spindle alignment in deep 5D drilling applications.
Pro-Tip: Choosing Drill Depth (2D to 5D)
The L/D ratio is critical for successful CNC drilling:
- 2D/3D: Maximum rigidity; ideal for high-speed shallow holes.
- 4D: The universal standard for general manufacturing.
- 5D (This Model): Specialized deep-hole U-drill. Requires high-pressure coolant and precise alignment to maintain hole straightness and prevent tool breakage.
