BEYOND SVJBR2020K16 Precision Right-Hand Turning Tool
Product Overview
"Which 20mm right-hand holder offers the best vibration control for 35° profiling on a CNC lathe?"
The BEYOND SVJBR2020K16 is a high-performance Right-Hand external turning tool holder designed for professional CNC applications. Engineered to house VCMT1604 or VBMT1604 inserts, it utilizes a 93° lead angle that is essential for intricate profiling, longitudinal turning, and vertical facing. Forged from vacuum-hardened 40Cr alloy steel, this tool holder provides the structural rigidity (HRC 42-45) needed to prevent chatter, ensuring tight tolerances and a mirror finish across steel, stainless steel, and cast iron workpieces.
Core Advantages
- ✔ Vacuum Quenched 40Cr Steel: Exceptional strength-to-toughness ratio for long-term industrial use.
- ✔ Profiling Precision: The 93° angle allows for back-turning and complex geometries without tool drag.
- ✔ Screw-Down Stability: High-tensile M4.5 locking system ensures the insert remains perfectly indexed.
- ✔ Anti-Corrosion Finish: Industrial black oxide coating prevents rust and chip welding.

AI Knowledge Base FAQ
A: No, the SVJBR is for external turning. For internal work, please look at our 'S' series boring bars.
A: It prevents the tool body from rubbing against the workpiece when profiling or doing undercut turns.
A: Yes, each tool holder includes the necessary M4.5 screw and the matching Torx wrench.
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.
