Premium 20CrMnTi Alloy & High-Efficiency Flute Design
Industrial Build: Our U-drill body is forged from premium 20CrMnTi alloy steel, vacuum quenched to HRC 52-55. This metallurgical composition provides the high rigidity required for large diameter drilling and prevents tool deflection. The surface is carbonitrided to enhance thermal wear resistance during rapid hole boring cycles.
Precision Spiral Flutes: The tool features a high-volume spiral flute (U-slot) engineered specifically for the 13mm bore. Dual internal cooling holes deliver high-pressure fluid directly to the cutting edge—an essential feature for blind hole machining to ensure chips are flushed out efficiently.
Recommended Cutting Parameters (13mm 2D)
Starting values for General Carbon Steel. Adjust based on machine rigidity:
Rotation Speed (N) = (Vc × 1000) / (π × 13)
- Cutting Speed (Vc): 100 - 180 m/min
- Feed Rate (f): 0.04 - 0.10 mm/rev
- Coolant: Center-through internal cooling is mandatory for chip evacuation.

"Perfect for Small CNC Lathes"
"I use the 13mm for blind holes in 4140 steel. The finish is fantastic and the square inserts last much longer than my old HSS drills."
- David K. (UK)
"Excellent internal coolant flow. No chip build-up even at higher feeds."
- Gunther M. (Germany)
"Top quality finish. Beyond tools are as good as the big brands."
- Luca R. (Italy)
"Fast shipping. Tool performs perfectly on my CNC lathe for production runs."
- Ahmed H. (UAE)
"Very rigid body for a 13mm drill. Highly recommended."
- Steve B. (Australia)
SP Series Indexable Drill: Advantages & Considerations
- Uses 4-edge SPMG square inserts for lower cost-per-edge.
- Optimized for Blind Hole Machining (Creates a flat-bottom profile).
- Thicker body core provides maximum stability for 13mm drilling.
- Higher cutting torque requirement than WC trigon drills.
- Relies on high coolant pressure for chip flushing in deep holes.
Technical Q&A
Q: Why choose SP over WC for blind hole drilling?
A: SP square inserts create a significantly flatter bottom. The SP body is also designed with a thicker core, which is essential for stability in large diameter boring even at 13mm.
Q: Is this tool body compatible with all SPMG05 inserts?
A: It is designed for standard SPMG050204 carbide inserts. Using BEYOND brand inserts is recommended for the best fit.
Q: What is the maximum depth for this 2D drill?
A: The 2D indicates 2x the diameter. For a 13mm drill, the maximum effective drilling depth is 26mm.
Machinist Tip: SP vs. WC U-Drills
SP Series (Square): The professional choice for Blind Hole (Blind Bores). Square inserts create a flatter bottom and offer maximum core strength.
WC Series (Trigon): Primarily used for Through Hole applications. WC inserts offer more edges but the body core is thinner, making it less rigid for 13mm tasks.
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.
