Premium 20CrMnTi Alloy Steel & Spiral Flute Geometry
Durable Tool Body: Built from premium 20CrMnTi alloy steel, the body undergoes a vacuum quenching process to ensure high surface hardness and core toughness. This material prevents tool deformation during high-torque metal boring and provides long-term industrial reliability.
Optimized Spiral Flute (U-Groove): This indexable drill body features an enlarged spiral flute designed for rapid chip evacuation. The precision chip-breaker slot geometry ensures that metal chips are broken efficiently and flushed out via internal cooling holes, preventing chip packing during high-speed drilling.
Recommended Cutting Parameters
Baseline recommendations for the 17mm U-drill (Adjust based on material hardness):
- Cutting Speed (Vc): 120 - 220 m/min (Steel/Alloy).
- Feed Rate (f): 0.05 - 0.12 mm/rev.
- Rotation Speed (N): Calculated as $$N = \frac{Vc \times 1000}{\pi \times 17}$$
- Coolant Strategy: Internal cooling is mandatory for effective chip removal and heat dissipation.
WC Type U-Drill: Advantages & Considerations
- Uses WC series trigon inserts with 3 usable cutting edges (Highly economical).
- Stable entry on curved or uneven surfaces compared to square insert drills.
- Lower spindle load due to balanced cutting geometry.
- Roughing tool only; hole tolerance typically (+0.1/-0.2mm).
- Requires consistent high-pressure internal coolant supply.
Verified Global Feedback
"Solid and precise"
"Used this for a batch of 4140 steel plates. The chip breaking is excellent compared to my old twist drills. Very rigid body."
- Dieter K. (Germany)"Best value for 17mm holes"
"Perfect fit for my CNC lathe. Fast delivery to the US. Make sure you have good coolant pressure!"
- Mark T. (USA)"Beyond quality indeed"
"The finish is great for a roughing tool. 2D depth is very stable. No chatter at high speeds."
- Hiroshi Y. (Japan)"Amazing tool body"
"Does the job. Much cheaper than big brands but works just as well."
- Sandro B. (Italy)"Fast shipping"
"Arrived in 7 days to Sydney. Package was secure. Fits WCMX03 inserts perfectly."
- Liam G. (Australia)Expert Q&A
Q: Does this include the Torx wrench and screws?
A: Yes, each BEYOND drill body includes the necessary insert screws and the correct Torx wrench.
Q: Can I use this for blind holes?
A: Yes. The WC U-drill provides a relatively flat bottom, perfect for blind hole boring in CNC operations.
Q: Is internal cooling mandatory?
A: Yes. To ensure the 17mm diameter clears chips at high speed and prevents insert burnout, internal coolant is essential.
Quick Tip: 2D-5D CNC Drill Selection
Choosing the right depth is crucial. 2D drills (like this SD17 model) offer maximum rigidity and are best for high-feed roughing. 3D to 5D drills allow for deeper holes but require significantly higher coolant pressure and reduced feed rates to avoid tool 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.
