BEYOND SVUCR2525M16
Right-Hand 25mm External Profiling Tool Holder
Product Overview
"Which high-rigidity tool holder is best for aggressive profiling and external finishing using 35-degree diamond inserts on large CNC lathes?"
The BEYOND SVUCR2525M16 is a professional-grade, right-hand external turning tool holder engineered for precision profiling. Designed for use with VCMT1604 or VCGT1604 inserts, this 25x25mm shank holder features a 93° approach angle. This geometry is specifically optimized for clearing complex contours while maintaining maximum rigidity, effectively eliminating vibration during high-speed finishing passes in steel, stainless steel, and cast iron.
Core Industrial Advantages
Quenched Alloy Steel
Forged from high-tensile alloy steel (HRC 42-45) to ensure durability and resistance to thermal deformation during prolonged runs.
Screw-On Clamping Stability
The precision-machined screw-on system provides a low-profile head for better chip clearance and unmatched insert security.
93° Profiling Precision
The 93-degree approach allows the tool to face and turn profiles with a single setup, reducing cycle time and increasing accuracy.

Industrial User Feedback
Solid and Reliable
"Zero chatter on my 4140 steel shafts. The 25mm shank is beefy and handles the load well."
— David K., USA 🇺🇸Precision Fit
"BEYOND holders always deliver. The V-insert pocket is perfect; repeatability is excellent."
— Gerhard S., Germany 🇩🇪Great Value
"Using this for profiling stainless. Holds up much better than cheaper generic brands."
— Antonio R., Italy 🇮🇹Technical FAQ
Q: What is the difference between SVUCR and SVUCL?
A: SVUCR is a Right-Hand (R) tool holder, while SVUCL is the Left-Hand version. Most standard lathe setups use Right-Hand tools for OD turning towards the chuck.
Q: Can I use both VCMT and VCGT inserts?
A: Yes. Both VCMT (Steel semi-finishing) and VCGT (Aluminum/Finishing) 1604 size inserts will fit this holder perfectly as they share the same base geometry.
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.
