The AS5202-X will cut the required spot face and counterbore only; it does not cut the thread minor diameter. A coolant hole to each flute aids with increased chip evacuation, higher speeds and feeds, and longer tool life. The polished flute face optimizes performance for a smoother surface finish. The body of the port tool is made of heat- treated alloy steel and the brazed inserts are made of premium quality sub-micron carbide.
