Cemented Carbide Taps ●The flute shape develops less flute damage · The MC-AD-CT is a ultra fine grain cemented carbide tap ⑤ with superior wear resistance · The superior carbide combined with an optimum coating produces a 5 times longer tool life than conventional aluminum taps. ●The center through coolant hole shape is designed for internal lubrication and mist applications. The lubrication or air lowers the temperature by cooling even in dry tapping. It is effective in removing chips from the pilot hole during tapping and prevents chip welding.
