Six flute end mills are generally used for finishing or high efficiency milling (HEM) operations. The increased number of flutes means higher feed rates and productivity. These are available in mostly high performance and general purpose geometries. They come in square end and corner radius designs with and without variable pitch.
Two flute end mills are used for all end mill operations. The flute volume is more with 2 flute mills, but the feed rates are lower. The fewer number of flutes allows for better chip evacuation in grooving operations. These mills come in flute lengths stub, standard, long, and extra extra long. The end geometry can be square, ball or corner radius.
5/8" (Inch) End Mills. These 5/8" end milll bits have a cutting diameter and shank diameter of 5/8 (0.6250"). They come in ball end, square end, corner radius, and high performance variable flute geometries. They come as uncoated solid carbide, and as PVD coated with AlTiN, AlCrN, TiN, TiCN, and ZrN. The come in 2, 3, 4, and 6 flutes.
End mills with higher counts of 5, 6, and 7 flutes are increasingly being used to cut harder materials, as a higher flute count allows for a tool with more strength and less wear, resulting in a longer tool life. High flute counts can also be beneficial in specialty applications when dealing with certain kinds of ferrous materials.

· A roughing end mill with serrations on the cutting edges assist with material removal and a smooth edge version for finishing. These tools have a special ground geometry specifically for machining copper. The tool is balanced and strong, producing minimal vibrations which translates into good surface finishes. Our triple fluted tools are better ...
The new Z-Carb HPR Five Flute Roughing End Mills are ideal for achieving high metal removal rates (MRR) and a finish of 80 RMS or better on most materials. The specialized five flute design is engineered for increased productivity over three and four flute end mills. The variable indexing geometry allows for improved chatter suppression over ...
