this drops directly into static block stations designed for 1-1/4 inch round boring bar bodies utilizing metric tool conversion sleeves

use a CVD coated carbide grade

External reverse threading is notoriously prone to harmonic micro-vibrations because the pointed nose geometry of threading inserts creates concentrated tool pressure

Advantages:Superior oxidation resistance with well balanced wear resistance and toughness
