Advanced Machining Logic & Rigidity
The 266RKF-32-16 is a professional-grade Internal Threading Boring Bar specifically engineered for high-performance CNC turning applications. At the core of its design is the proprietary iLock™ interface, a rail-shaped Insert Seat that eliminates tangential forces and micro-vibrations during the metal drilling and threading process. By maximizing Clamping Stability, this tool ensures precise thread pitch and exceptional Stability, even when machining challenging alloy steel and stainless steel workpieces.
