  • Three flutes provide better chip-carrying capacity than four flutes and a finer finish than two, reducing the need for a second finishing cut in some applications
  • Square nose end mills (also called square end) create sharp, unrounded cuts
  • Titanium aluminum nitride (TiAlN) coating lubricates the end mill for high-temperature stability and abrasion resistance at high cutting speeds, offering better heat resistance than TiN and TiCN coatings
  • Carbide can run at higher speeds than high-speed steel, resisting abrasion and high cutting temperatures
  • Center-cutting design allows the end mill to plunge into material like a drill bit while also performing conventional surface milling
