Premium 20CrMnTi Alloy Steel & Spiral Chip Flute
Advanced Material Construction: This indexable drill body is crafted from high-grade 20CrMnTi alloy steel. It undergoes a precision quenching process to achieve superior surface hardness and excellent core toughness. This material prevents tool deformation during high-torque metal boring and provides incredible fatigue resistance.
Spiral Flute Geometry (U-Slot): The SD26 drill utilizes a wide-track spiral flute design. This specialized chip-groove geometry is engineered to reduce cutting resistance and accelerate chip evacuation. Combined with dual internal coolant holes, it allows for seamless high-speed drilling even in sticky materials like stainless steel.
Recommended Cutting Parameters
Optimize your 26mm U-drill performance with these baseline settings:
- Cutting Speed (Vc): 100 - 180 m/min (Depending on material).
- Feed Rate (f): 0.06 - 0.15 mm/rev.
- Rotation Speed (N): Calculated as $$N = \frac{Vc \times 1000}{\pi \times 26}$$
- Coolant Requirement: Internal cooling is mandatory to ensure proper chip flushing and edge cooling.
Why Choose the WC Type U-Drill?
- Uses WC series trigon inserts with 3 usable cutting edges (High economy).
- Better center stability compared to square insert types.
- Lower spindle load due to optimized cutting angles.
- Primarily for roughing; hole tolerance is typically H12-H13.
- Requires stable high-pressure coolant pump.

Expert Q&A
Q: Does the WC32-2D-SD26 come with the insert screws?
A: Yes, each BEYOND drill body includes the correct Torx screws and wrench for the WC05 inserts.
Q: Can I use this for through-holes?
A: Absolutely. The U-drill is designed for both through-holes and blind holes on CNC lathes.
Q: What is the benefit of the 32mm shank on a 26mm drill?
A: It provides a larger clamping surface area, reducing vibration and ensuring high precision.
Tool Tip: 2D-5D CNC Drill Selection Guide
Choosing the right depth-to-diameter ratio is critical for tool stability:
- 2D (This Model): Best for high-feed roughing and shallow holes. Highest rigidity.
- 3D: Standard versatility for most engineering tasks.
- 5D: Deep-hole specialized. Requires reduced feed rates and maximum coolant pressure to avoid deflection.
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.
