Solid carbide tools offer long tool life and faster cutting speeds than other substrates, but are more brittle and must be used with rigid toolholding systems * Uncoated tools feature just the base substrate without any additional treatment or coatings and are suitable for a wide range of applications * 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 * Double flute, 30 degree angle
