BEYOND SVUBR2020K11 Right-Hand External Turning Tool Holder
Product Overview
"Which 20mm right-hand tool holder is most stable for 93° profiling and high-precision finishing with VBMT 1103 inserts?"
The BEYOND SVUBR2020K11 is a professional-grade Right-Hand (R) external turning tool holder with a robust 20x20mm shank. Specifically designed for 35° rhombic VBMT 1103 or VCMT 1103 inserts, it is the industrial standard for precision profiling. Its 93° approach angle provides superior clearance for contouring while maintaining maximum rigidity in steel, stainless, and alloy workpieces.
Key Features
- ✔Quenched Alloy Steel: Heat-treated to HRC 42-45 for superior vibration resistance and high-tensile strength.
- ✔93° Profiling Geometry: Optimized lead angle for complex contouring and longitudinal turning without radial deflection.
- ✔S-Type Screw Locking: Simplified high-precision locking mechanism ensures rapid indexing and rock-solid insert seating.
- ✔Anti-Corrosion Black Oxide: Premium surface treatment prevents chip welding and oxidation in wet machining environments.

Verified Industrial Feedback
"Perfect Profiling"
Mark T. (USA) - Fits our turret perfectly. The 93-degree angle gives exactly the clearance we need for profiling intricate parts.
"Solid and Reliable"
Hans B. (Germany) - Vacuum hardened steel makes a difference. No vibration at high speeds. Very accurate insert seat.
"Excelente Calidad"
Roberto L. (Italy) - Great surface finish on stainless. Fast indexing and simple screw clamping. Highly recommended.
"Industrial Standard"
S. Tanaka (Japan) - Consistent performance across large batches. Standard ISO sizing is precise. Good value.
Technical Support FAQ
A: While the 20mm shank is robust, the 35° VBMT insert is specialized for fine finishing and medium profiling. For heavy roughing, we recommend a CNMG or WNMG holder.
A: Yes, it is fully compatible with both VBMT 1103 and VCMT 1103 standard ISO inserts.
A: Yes, every BEYOND tool holder package includes the correct high-tensile locking screw and the matching Torx wrench.

Equivalent Models: Sandvik SVUBR-2020K11, Kennametal SVUBR2020K11, Iscar SVUBR-2020-K11.
Troubleshooting: If tool vibration occurs, minimize tool overhang and ensure the center height is correctly aligned within ±0.1mm.
Grade Tip: Pair with BEYOND BY815 for high-speed steel turning or BYM25 for heat-resistant alloys.
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.
