BEYOND WC32-4D-SD32-WC06
High-Rigidity 4D Indexable U-Drill | 32mm Precision CNC Drilling
Industrial-Grade 32mm Indexable Drill
The BEYOND WC32-4D-SD32-WC06 is a professional indexable insert drill engineered for heavy-duty metal removal. Featuring a 32mm cutting diameter and a 4D depth-to-diameter ratio, this tool is the ultimate choice for high-speed internal cooling drilling. It is optimized for processing carbon steel, alloy steel, and stainless steel with maximum stability during large hole CNC machining.
Model Code Specification
Metric & Imperial Technical Data

Recommended Cutting Parameters
Maximize metal holemaking efficiency with these standard settings for BEYOND U-Drills:
- Cutting Speed (Vc): 120 - 200 m/min (Depending on material hardness).
- Feed Rate (f): 0.05 - 0.15 mm/rev.
- Coolant: Internal high-pressure coolant is strongly recommended to ensure chip evacuation in 4D depths.
Alloy Steel Material & Spiral Flute Design
Constructed from high-performance alloy steel with an advanced quenching process, this WC06 insert holder offers exceptional anti-vibration properties. The wide spiral flute geometry is specifically designed for "forced" chip removal, preventing chip welding and clogging—the primary causes of tool failure in 32mm deep hole drilling. The tool body is treated with a nickel-plated coating for enhanced wear resistance.
WC Series U-Drill: Advantages & Disadvantages
- Uses WCMX / WCMT inserts with 3/4 cutting edges (Cost-effective).
- Exceptional stability on uneven entry surfaces.
- High efficiency compared to traditional twist drills.
- Requires high spindle power for 32mm bores.
- Surface finish may be slightly rougher than specialized boring tools.
Pro-Tip: 2D vs 3D vs 4D vs 5D Selection
The L/D ratio (Length/Diameter) determines your CNC tooling strategy:
- 2D/3D: Best rigidity; suitable for high-feed roughing and shallow holes.
- 4D (Current Model): The versatile standard for deep-hole drill bit applications.
- 5D: Extreme reach; requires superior coolant pressure and lower feed rates to maintain hole straightness.
Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
