BEYOND WC25-5D-SD22.5-WC04
High-Performance 5D Indexable U-Drill | Precision Deep-Hole Machining
Advanced 22.5mm CNC Drilling Technology
The BEYOND WC25-5D-SD22.5-WC04 is an industrial-strength indexable insert drill engineered for extreme metal removal rates. Featuring a 22.5mm cutting diameter and a 5D depth-to-diameter ratio, this tool is the definitive choice for high-speed internal cooling drilling. It is optimized for processing carbon steel, alloy steel, and stainless steel with maximum structural rigidity.

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.

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.
