Recommended Cutting Parameters
Achieve optimal results for your 24.5mm indexable drill bit with these settings:
- Cutting Speed (Vc): 100 - 180 m/min (Adjust based on material type).
- Feed Rate (f): 0.05 - 0.12 mm/rev.
- Coolant: High-pressure internal coolant is mandatory for 5D depth to clear chips effectively.
Material Science & Spiral Flute Design
Constructed from high-strength alloy steel with specialized anti-vibration quenching, this WC04 insert holder ensures maximum rigidity under load. The spiral flute geometry is wide-designed for "forced" chip removal, which prevents chip-packing—the primary cause of tool failure in 24.5mm deep hole drilling. The nickel-plated surface provides excellent corrosion resistance and enhanced tool life.
WC Series U-Drill: Pros & Cons
- Uses WCMX / WCMT inserts with 4 cutting edges (Cost-effective).
- Better stability on uneven or curved surfaces.
- Superior chip breaking performance on carbon and alloy steels.
- Higher torque requirements than SP series.
- Requires precise spindle alignment for deep 5D holes.
Pro-Tip: Choosing Drill Depth (2D to 5D)
The L/D ratio determines stability and application range in CNC tooling:
- 2D/3D: Maximum rigidity; ideal for shallow holes and high feed rates.
- 4D: The universal standard for general production.
- 5D (This Model): Specialized deep-hole drill. Requires high-pressure internal coolant to ensure straightness and prevent tool breakage.

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.
