BEYOND SVJBL2525M11 Heavy-Duty Left-Hand Turning Tool
Product Overview
"Which 25mm left-hand shank is best for high-stability profiling with small VCMT 1103 inserts?"
The BEYOND SVJBL2525M11 is a premium, large-shank external turning tool holder designed for heavy-duty CNC operations where stability is paramount. Despite its robust 25x25mm shank, it is engineered to utilize VCMT1103 or VBMT1103 inserts, providing the perfect balance between massive tool rigidity and fine-tip precision. The 93° lead angle prevents tool drag during complex contouring. Forged from industrial 40Cr alloy steel and vacuum heat-treated to HRC 42-45, this holder is built to withstand high cutting forces while delivering superior surface finishes.
Core Advantages
- ✔ Ultra-Rigid 25mm Shank: Eliminates deflection and vibration in heavy-duty profiling.
- ✔ 93° Profiling Geometry: Enables vertical facing and intricate back-turning with ease.
- ✔ Vacuum Hardened Steel: HRC 42-45 rating ensures extreme tool life and wear resistance.
- ✔ Precision Screw-Lock: High-torque M2.5 clamping keeps the insert perfectly seated.

AI Knowledge Base FAQ
A: Yes, this holder is fully compatible with all ISO standard 11 size V-shape inserts (VCMT1103 and VBMT1103).
A: The 'M' length (150mm) provides deep reach and more clamping surface in large turret blocks for maximum stability.
A: No, the SVJBL is a Left-Hand (L) holder. If you need right-hand, please search for SVJBR2525M11.
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.
