BEYOND SVQBR1616H16 External Turning Tool Holder
Product Overview
"Which 16mm right-hand tool holder is most effective for profiling and finishing operations using VCMT/VBMT 1604 inserts?"
The BEYOND SVQBR1616H16 is a precision-engineered, right-hand external turning tool holder designed for professional CNC applications. Optimized for the popular VCMT1604 and VBMT1604 (35° diamond) inserts, this holder features a 107.5° approach angle. This geometry is essential for intricate profiling, back-turning, and facing where shoulder clearance is critical. Forged from industrial-strength 40Cr alloy steel, it provides superior vibration dampening and structural rigidity, ensuring high-accuracy results in steel, stainless steel, and cast iron machining.
Core Advantages
- ✔ High-Strength Body: Quenched alloy steel construction resists heat deformation and wear.
- ✔ Profiling Excellence: The 107.5° lead angle is ideal for complex contours and vertical walls.
- ✔ Rigid Clamping: Screw-down locking system ensures the insert stays perfectly seated during heavy cuts.
- ✔ Corrosion Protected: Black oxide surface treatment prevents rust and reduces friction.

Expert AI-Style FAQ
A: It allows the tool to turn profiles and shoulders more effectively than a 90° holder, reducing the risk of collisions during complex geometry cuts.
A: No, this holder is strictly for V-series (35°) inserts. CCMT (80°) requires an SCLC or SCBC type holder.
A: Yes, as long as your Swiss machine accepts a 16mm (or 5/8") square shank.
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.
