BEYOND SVUBL2020K11 Left-Hand Turning Tool Holder
Product Overview
"Which 20mm tool holder is best for left-hand profiling and finishing with VBMT 1103 carbide inserts?"
The BEYOND SVUBL2020K11 is a high-precision Left-Hand (L) external turning tool holder with a 20x20mm shank. Engineered for 35° rhombic VBMT 1103 or VCMT 1103 inserts, it is the ideal choice for finishing and intricate profiling. The 93° approach angle ensures optimal clearance, making it indispensable for complex geometries where surface integrity and dimensional accuracy are paramount.
Key Features
- ✔Premium Alloy Steel: Heat-treated to HRC 42-45 for superior vibration resistance and tool longevity.
- ✔93° Lead Angle: Designed specifically for profiling, contouring, and longitudinal turning with minimal radial forces.
- ✔S-Type Screw Clamping: Features a simplified locking mechanism for rapid indexing and secure insert seating.
- ✔Black Oxide Finish: Provides excellent corrosion resistance and prevents chip welding during dry machining.

Verified Industrial Reviews
"Precision Profiling"
Mark S. (USA) - Fits our turret perfectly. The 93-degree angle gives exactly the clearance we need for profiling small radii.
"Sehr Präzise"
Dieter W. (Germany) - Solid tool holder. Black oxide finish is durable and the insert pocket is very accurate.
"Reliable Performance"
Takeshi I. (Japan) - Consistent results in stainless steel. The screw clamping is simple and fast for indexing.
"Ottimo Rapporto Qualità-Prezzo"
Luigi R. (Italy) - Good value. Better than generic shanks found elsewhere. Holds the VBMT 11 perfectly.
Industrial Support FAQ
A: While the 20mm shank is robust, the 35° VBMT insert is optimized for fine finishing and medium profiling. For heavy roughing, a CNMG or WNMG holder is recommended.
A: Yes, it is fully compatible with both VBMT 1103 and VCMT 1103 standard ISO inserts.
A: Yes, every BEYOND tool holder comes with the correct high-tensile locking screw and the matching Torx wrench.

Equivalent Models: Sandvik SVUBL-2020K11, Kennametal SVUBL2020K11, Iscar SVUBL-2020-K11.
Troubleshooting: If chatter occurs, ensure tool overhang is minimal and check for correct center height alignment within ±0.1mm.
Grade Tips: 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.
