BEYOND SVVBN2525M16 External Turning Tool Holder
Product Overview
"Which 25mm neutral holder is best for 72.5° profiling and multi-directional turning on steel components?"
The BEYOND SVVBN2525M16 is a professional-grade, neutral-hand (N) external turning tool holder with a standard 25x25mm shank. Engineered for the 35° rhombic VBMT 1604 or VCMT 1604 inserts, it is the industrial choice for precision profiling and longitudinal turning. The 72.5° approach angle provides optimized clearance for complex contours, ensuring superior stability and surface finish in both steel and stainless steel machining.
Key Features
- ✔High-Performance Alloy Steel: Hardened to HRC 42-45 for exceptional vibration resistance.
- ✔72.5° Lead Geometry: Ideal for profiling and facing with minimal radial force.
- ✔Neutral Hand Versatility: Can be used in multiple orientations for maximum turret flexibility.
- ✔Black Oxide Finish: Provides superior corrosion protection and aesthetic durability.

David R. (USA) - The neutral hand is great for my setup. Holds the VBMT insert perfectly with zero chatter.
"Sehr stabil"
Marcus K. (Germany) - Solid tool life and the 25mm shank is very rigid. Perfect for my DMG turret.
"Ottima fattura"
Pietro M. (Italy) - High quality finish and fast shipping. Accurate center height.
"Consistent Quality"
S. Tanaka (Japan) - Standard ISO fit. Good performance on alloy steels.
Industrial Support FAQ
A: A neutral holder is centered, allowing it to be used in either right or left directions depending on the turret and machine rotation, providing greater versatility.
A: The SVVBN series is optimized for profiling and medium finishing. For heavy roughing, we recommend using CNMG or WNMG tool holders.
A: Yes, each SVVBN2525M16 includes the correct clamping screw and the corresponding Torx wrench.
Grade Tip: Combine with BY815 for multi-material steel or BYM25 for dedicated stainless steel turning.
Equivalent Models: Sandvik SVVBN-2525M16, Kennametal SVVBN2525M16, Iscar SVVBN-2525-M16.
Troubleshooting: If vibration occurs, check tool overhang and ensure center height is exact. Torquing the insert screw to 3.0 Nm is recommended.

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.
