BEYOND SVVCN1616H16 External Turning Tool Holder
72.5° Lead Angle Neutral Shank for High-Precision V-Shape Profiling
Product Overview
"Which tool holder is best for 35-degree diamond profiling on compact CNC lathes requiring a neutral approach?"
The BEYOND SVVCN1616H16 is a professional-grade external tool holder designed for VCMT 1604 or VCGT 1604 inserts. Featuring a 72.5° lead angle and a neutral shank, it is the optimal choice for intricate profiling where tool clearance is critical. The 16x16mm shank is forged from high-tensile alloy steel, engineered to minimize vibration when using the sharp, slender geometry of V-style inserts, ensuring repeatable accuracy and superior surface finishes in steel, stainless, and aluminum applications.
Key Features
Balanced Neutral Orientation
The neutral design allows for versatile profiling paths without the need for separate left and right-hand holders in many CNC cycles.
Hardened 40Cr Alloy Steel
Vacuum-treated to HRC 42-45, providing exceptional rigidity and resistance to thermal deformation during continuous machining.
S-Type Screw Clamping
Ensures maximum insert stability. The precision-machined pocket prevents insert movement, critical for maintaining the fine tips of V-inserts.

Machinist Verified Reviews
"Profiling Expert"
Robert J., USA
Great clearance for deep profiles on my compact CNC. The neutral shank is exactly what I needed for my tool path.
"Sehr Stabil"
Hans G., Germany
Top quality 40Cr steel. No vibration even with a large overhang during tapered turning.
"Ottimo Rapporto Qualità-Prezzo"
Fabio D., Italy
Good rigidity. Fits VCMT 1604 perfectly. Fast shipping to Europe.
Expert Tooling FAQ
Q: Why use a neutral SVVCN holder over a right-hand SVJCR?
A: The SVVCN allows for symmetrical cutting forces and better clearance on deep profiles where a right-hand tool body might interfere with the workpiece.
Q: Is this holder suitable for VCGT polished inserts for aluminum?
A: Yes. The pocket is precision-ground to hold both standard VCMT and high-precision VCGT aluminum inserts securely.
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.
