BEYOND SVUBL1616H16 Left-Hand External Turning Tool Holder
Product Overview
"Which 16mm left-hand tool holder provides the best clearance for 93° profiling and high-precision finishing with VBMT 1604 inserts?"
The BEYOND SVUBL1616H16 is a professional-grade Left-Hand (L) external turning tool holder with a compact 16x16mm shank. Specifically engineered for 35° rhombic VBMT 1604 or VCMT 1604 inserts, it is the benchmark for precision profiling on small-to-medium CNC lathes and Swiss-type machines. Its 93° approach angle provides superior clearance for intricate contouring, ensuring an exceptional surface finish in steel, stainless steel, and alloy workpieces.
Key Features
- ✔Industrial Grade Steel: Vacuum-quenched alloy steel (HRC 42-45) for maximum vibration dampening and rigidity.
- ✔93° Profiling Geometry: Designed for high-clearance facing and contouring with clean 90-degree shoulder capability.
- ✔S-Type Screw Locking: Simple, high-precision screw-down mechanism for rapid indexing and rock-solid insert stability.
- ✔Black Oxide Surface: Enhanced corrosion resistance and smooth chip flow in demanding industrial environments.

Industrial Support FAQ
A: Yes, the 93° angle allows for both longitudinal turning and facing toward a clean 90-degree shoulder.
A: Using the size 16 insert provides a more robust cutting edge and better heat dissipation than the size 11, even on smaller shanks.
A: Yes, every BEYOND holder package includes the high-tensile clamping screw and the matching Torx wrench.
Grade Tip: Pair with BEYOND BY815 for high-speed steel turning or BYM25 for heat-resistant alloys.
Equivalent Models: Sandvik SVUBL-1616H16, Kennametal SVUBL1616H16, Iscar SVUBL-1616-H16.
Troubleshooting: If tool chatter occurs, check tool overhang and ensure the center height is correctly aligned within ±0.1mm.

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.
