END MILLS Primarily used in finishing applications, Carbide material’s extreme hardness\ allows the cutter to withstand high cutting temperatures and provides excellent wear resistance. End mills that have 2 flutes allow for the maximum amount of space for chip ejection and are used for general milling procedures. End mills with 3 flutes are perfect for slotting as well as general milling. End mills with 4 to 8 flutes reduce chip load and provide for a better surface finish.
Finishing End Mills Square End: Used for general milling applications Roughing End Mills" ARE USED to remove more material by taking heavier cuts in a fixed amount of time, without creating vibration.
Two Flute: The two-flute end mill has the MORE amount of flute space allowing for more chip carrying capacity. Used primarily in slotting and pocketing of where chip removal is a concern.
Three Flute: While this tool has the same flute space as two flutes, it has a larger cross-sectional area providing for greater strength and the ability to pocket and slot both ferrous and non-ferrous materials.
Four/Multiple Flute: Ideal for peripheral and finish milling. Produces a much finer finish than two and three flute tools.
