BEYOND SVUBR2020K16 Right-Hand Turning Tool Holder
Product Overview
"Which 20mm right-hand tool holder is best for high-stability 93° profiling and finishing with VBMT 1604 inserts?"
The BEYOND SVUBR2020K16 is a professional-grade Right-Hand (R) external turning tool holder with a 20x20mm shank. Specifically engineered for 35° rhombic VBMT 1604 or VCMT 1604 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 dampening and shock resistance.
- ✔93° Profiling Geometry: Designed for high-clearance facing and contouring with 90-degree shoulder capability.
- ✔Secure S-Type Locking: High-precision screw-down mechanism ensures rapid indexing and insert stability under load.
- ✔Anti-Corrosion Black Oxide: Premium surface treatment enhances chip flow and prevents oxidation in wet machining.

The 20mm shank is optimized for medium-duty CNC lathes and turning centers. It excels in external profiling where high precision and tool clearance are required. Fully compatible with machine turrets from Mazak, Haas, Doosan, Okuma, and DMG Mori.
Industrial User Feedback
"Perfect Profiling"
John D. (USA) - The 20mm shank is surprisingly rigid. Use it for complex contouring on alloy steel daily.
"Excelente Acabado"
Carlos M. (Spain) - The 93 degree angle gives me great clearance. Surface finish is top tier with Beyond inserts.
"Precise & Reliable"
H. Schmidt (Germany) - Vacuum hardening shows in the tool life. Pocket precision is spot on for the VBMT 16 series.
"Good Value"
Y. Tanaka (Japan) - Standard ISO fit. Fast indexing. Does exactly what it needs to at a better price point.
Technical Support FAQ
A: While the 35° VBMT shape is ideal for finishing and profiling, the robust 20mm shank and size 16 insert allow for light-to-medium roughing in many materials.
A: Yes, it is fully compatible with both VBMT 1604 and VCMT 1604 standard ISO inserts.
A: Yes, each holder includes the screw and wrench. We also stock replacement parts for long-term maintenance.

Equivalent Models: Sandvik SVUBR-2020K16, Kennametal SVUBR2020K16, Iscar SVUBR-2020-K16.
Troubleshooting: If tool vibration occurs, check tool overhang and ensure center height alignment is 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.
