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.
