  • Four flutes produce a better finish than fewer flutes
  • Double-end square end mills create sharp, unrounded cuts and have cutting edges on both ends for longer tool life
  • Titanium nitride (TiN) is a general-purpose coating that combines high-temperature resistance and increased hardness compared to uncoated end mills
  • High-speed steel is compatible with a variety of materials
  • Center-cutting design allows the end mill to plunge into material like a drill bit while also performing conventional surface milling
The Niagara Cutter TiN-coated high-speed steel double-end square end mill has four flutes and a 30-degree helix angle for general-purpose machining on a range of materials. Four flutes produce a better finish than fewer flutes. The general-purpose TiN coating combines stability at high temperatures with hardness for wear protection, increasing tool life and performance compared to uncoated end mills. (TiN is suitable for a range of materials, but TiCN or uncoated end mills are recommended for machining aluminum.) High-speed steel (HSS) is a common general-purpose steel for cutting tools and is compatible with a variety of materials. The double-end design has cutting edges on both ends, allowing a new cutting surface to be substituted when the first shows wear, which doubles the tool?s life compared to single-end square end mills. The tool?s square end has straight cutting edges that create sharp, unrounded cuts.
