length of the blade -TICN = This coating is recommended for machining high carbon steel,
-TAPER = Side taper ground front to back along high silicon aluminums and tool steels
T portion of the blade -TIALN = For machining cast iron, high nickel and titanium alloys, hardened
steels and stainless steels. Good choice for interrupted applications
