BEYOND SVJBL1616H16 Precision Left-Hand Turning Tool
Product Overview
"Which 16mm left-hand tool holder is best for high-precision profiling with VCMT 1604 inserts?"
The BEYOND SVJBL1616H16 is an industrial-grade Left-Hand external turning tool holder specifically optimized for 16mm tool posts. Designed to support VCMT1604 and VBMT1604 35° diamond inserts, it features a 93° approach angle that excels in fine profiling and finishing where clearance is critical. Forged from high-grade 40Cr alloy steel and vacuum-quenched to HRC 42-45, this holder offers superior vibration dampening, ensuring exceptional surface finishes on steel, stainless, and non-ferrous materials.
Core Advantages
- ✔ High-Tensile 40Cr Steel: Maximum rigidity for chatter-free machining at high speeds.
- ✔ 93° Profiling Geometry: Allows for back-turning and vertical facing with zero tool body drag.
- ✔ Precision Screw-Lock: M4.5 torx screw ensures repeatable insert indexing and high clamping force.
- ✔ Industrial Finish: Anti-rust black coating enhances tool longevity in harsh coolant environments.

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.
