YG-1 Z7 series vanadium alloy HSS roll form tap with oil groove. High-speed steel tools are good for most general purpose applications, offering a combination of hardness and toughness for wear resistance. Titanium nitride coatings add a hard layer of gold-colored ceramic to the surface that extends tool life and permits faster cutting speeds than uncoated tools. Round shanks allow use with a wide variety of toolholding systems. Straight flute tools allow chips to collect in the flutes as they cut and are well suited for most applications in shallow cuts. Right-hand cut tools have a cutting action that engages when they are run in a clockwise direction. Applications: Excellent for low carbon/free machining carbon steel, medium to high carbon steel, free machining stainless steel, pure aluminum/aluminum alloys, aluminum alloy castings, pure and alloyed copper, free machining brass/alloyed brass, zine, magnesium.
