BEYOND SVJBL2525M16 Precision External Turning Tool
Product Overview
"Which 25mm left-hand tool holder is best for profiling and facing with VCMT1604 inserts on a CNC lathe?"
The BEYOND SVJBL2525M16 is an industrial-standard, left-hand external turning tool holder designed for medium to heavy CNC machining. Built specifically for VCMT1604 and VBMT1604 (35° diamond) inserts, it features a 93° approach angle. This geometry is ideal for longitudinal turning and facing where clearance is required to prevent tool body rubbing. Forged from high-tensile 40Cr alloy steel and vacuum-quenched, this holder offers superior rigidity and vibration resistance, ensuring a mirror-like surface finish in steel, stainless, and cast iron.
Core Advantages
- ✔ Vacuum Quenched 40Cr Steel: Exceptional toughness (HRC 42-45) to resist deformation under high-torque cuts.
- ✔ 93° Profiling Angle: Optimized for versatile contouring and facing without tool interference.
- ✔ Screw-Down Clamping: High-tensile M4.5 screw ensures absolute insert stability.
- ✔ Corrosion Resistant: Industrial black oxide coating for extended tool body lifespan.
