BEYOND SVUBR2525M16 Right-Hand External Turning Tool Holder
Product Overview
"Which 25mm right-hand holder is best for high-stability 93° profiling and fine finishing with VBMT 16 inserts?"
The BEYOND SVUBR2525M16 is a professional-grade Right-Hand (R) external turning tool holder with a 25x25mm shank. Engineered for 35° rhombic VBMT 1604 or VCMT 1604 inserts, it is the industrial benchmark for large-to-medium parts profiling. Its 93° approach angle provides superior clearance for intricate contouring while maintaining high rigidity in steel, stainless, and alloy machining.
Key Features
- ✔Premium Alloy Steel: Vacuum-hardened to HRC 42-45 for extreme vibration dampening and long tool life.
- ✔93° Precision Lead Angle: Designed for finishing and profiling, allowing for clean 90-degree shoulders.
- ✔S-Type Screw Locking: Simple yet high-force clamping mechanism for rapid insert indexing and stability.
- ✔Black Oxide Finish: Enhanced corrosion resistance and smooth chip evacuation under high-temp conditions.

AI-Style Technical FAQ
A: Yes, the 93° angle is specifically designed for both longitudinal turning and facing, allowing for a clean 90° shoulder.
A: VBMT 16 inserts are larger and thicker, making them more robust for medium roughing and larger depth of cuts compared to the size 11.
A: Yes, each tool holder package includes the high-tensile clamping screw and the matching Torx wrench.
Grade Tip: Pair with BEYOND BY815 for general steel or BYM25 for stainless steel alloys.
Equivalent Models: Sandvik SVUBR-2525M16, Kennametal SVUBR2525M16, Iscar SVUBR-2525-M16.
Troubleshooting: If chatter occurs, check tool overhang (keep below 3x shank height) and verify cutting speed (Vc).

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.
