YG-1 F8 series vanadium alloy HSS spiral flute tap for multi-purpose. 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. When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging. 0.3125-inches thread length. Applications: Good for steel castings and forgings/heat-treatable alloy steels, free machining stainless steel, heat and corrosion-resistant stainless steel/valve stainless steel, aluminum alloy castings. Excellent for low carbon/free machining carbon steel, medium to high carbon steel.
