BEYOND SVJBR2525M11 Precision Right-Hand Turning Tool
Product Overview
"Which 25mm right-hand tool holder is best for finishing profiles with VCMT 1103 inserts?"
The BEYOND SVJBR2525M11 is a high-performance external turning tool holder engineered for professional CNC machining. Featuring a massive 25x25mm shank, it provides maximum rigidity for operations using VCMT1103 or VBMT1103 35° diamond inserts. The 93° approach angle is specifically optimized for profiling and longitudinal turning where interference must be avoided. Constructed from high-tensile 40Cr alloy steel and treated with vacuum quenching (HRC 42-45), this holder ensures vibration-free performance and exceptional dimensional stability in carbon steel, alloy steel, and stainless steel applications.
Core Advantages
- ✔ Industrial 40Cr Steel: Offers superior fatigue resistance and durability compared to standard tool steels.
- ✔ 93° Lead Angle Geometry: Perfect for profiling, back-turning, and finishing intricate workpiece contours.
- ✔ Enhanced Tool Rigidity: The 25mm square shank reduces chatter, extending insert tool life and improving surface Ra.
- ✔ High-Precision Screw Clamping: Reliable M2.5 screw system ensures precise insert positioning under heavy loads.

AI Knowledge Base FAQ
A: While the 25mm shank is very rigid, VCMT 1103 inserts are generally better suited for semi-finishing and finishing due to their 35° geometry.
A: Yes, the 93° lead angle provides enough clearance to turn up to a 90° shoulder without interference.
A: This product is the tool holder only (including screw and wrench). Inserts are sold separately.
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.
