CoroThread 266 has iLock insert locking system that simplifies tool set-ups, eliminates potential insert movement during machining, and disperses cutting forces with no pressure points, reducing strain on both tool and insert. High-precision threading tool has axial and radial E-tolerance of 0.0004 and 0.002 in., respectively, minimizing effects of changing cutting edges to ensure maximum product consistency. Threading tool is intended for use in oil, gas, and mechanical engineering industries.
