High-Grade Material & Precision Flute Geometry
Premium Body Construction: This WC indexable drill is crafted from high-performance 20CrMnTi alloy steel. Through vacuum quenching, the body achieves exceptional toughness and surface hardness ($$HRC 50-55$$), providing superior resistance to vibration during high-speed boring.
Spiral Flute & Chip Breaker: The SD33.5 U-drill body features a precision-ground spiral flute designed for rapid chip evacuation. The optimized flute geometry reduces friction and prevents heat buildup. Integrated internal coolant channels ensure that chips are flushed away immediately, extending the tool life of your WCMX / WCMT carbide inserts.
Recommended Cutting Parameters
Achieve optimal results for your 33.5mm hole making with these settings:
- Cutting Speed (Vc): 100 - 180 m/min (Steel), 120 - 220 m/min (Alloy).
- Feed Rate (f): 0.06 - 0.15 mm/rev.
- Rotation Speed (N): Calculated as $$N = \frac{Vc \times 1000}{\pi \times 33.5}$$
- Coolant Strategy: Internal cooling is mandatory to clear chips efficiently.
WC Type U-Drill: Advantages & Considerations
- Uses WC series trigon inserts (3 cutting edges - cost-effective).
- Fast drilling speed with excellent hole surface finish.
- Stable entry on curved or uneven workpiece surfaces.
- Requires high spindle power compared to twist drills.
- Typical hole tolerance (+0.1 / -0.2mm); not for H7 precision.

Frequently Asked Questions
Q: Does the drill body include the WCMX inserts?
A: No, the price is for the 33.5mm U-drill body only. Inserts must be purchased separately.
Q: Can I use this for blind holes?
A: Yes, it is excellent for both through-holes and blind-holes in steel and stainless steel.
Q: What is the benefit of the 2D length?
A: 2D drills offer the highest rigidity, reducing deflection and allowing for faster feed rates compared to 3D or 5D versions.
Drilling Depth Selection: 2D-5D Comparison
Choosing the right depth-to-diameter ratio is critical for tool life:
- 2D (This Model): Max rigidity. Best for general shallow holes and high-feed roughing.
- 3D: Standard versatility for most industrial boring tasks.
- 4D-5D: Deep hole specialized. Requires higher coolant pressure and reduced feed rates to avoid tool breakage.
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.
