Recommended Cutting Parameters
Optimize your CNC lathe and milling machine performance for the WC40-4D-SD41-WC06:
- Cutting Speed (Vc): 110 - 160 m/min (Material dependent).
- Feed Rate (f): 0.07 - 0.14 mm/rev.
- Coolant Strategy: High-pressure internal coolant is mandatory for 41mm diameters to flush chips and ensure tool life.
Advanced Material & Chip Groove Design
This WC06 insert holder is manufactured from high-performance alloy steel with specialized anti-vibration quenching. The wide spiral flute geometry is designed for "forced" chip evacuation, preventing chip-packing—the primary cause of tool failure in large diameter drilling. The nickel-plated surface ensures superior corrosion resistance and reduces friction during deep hole machining.
WC Series U-Drill: Pros & Cons
- Uses WCMX / WCMT inserts with 4 cutting edges (Cost-effective).
- Stable entry even on uneven or curved workpiece surfaces.
- Excellent chip breaking on low-carbon and alloy steels.
- Requires high spindle torque for 41mm diameter operations.
- Sensitivity to spindle alignment for maximum 4D precision.
Tool Tip: Selecting Drill Depth (2D to 5D)
The L/D ratio is critical for CNC tooling success:
- 2D/3D: Highest rigidity. Best for general shallow holes.
- 4D (This Model): The balanced universal standard for industrial deep-hole machining.
- 5D: Specialized deep-hole drill bit. Requires extreme coolant pressure to flush chips.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
