The number of flutes is an essential part to control the performance of end mills. Generally, if there are few flutes, it is easy to discharge chips, but relatively section areas get smaller so that it makes the rigidity of tools fall down and enable tools to sway on cutting. On the other hand, if there are many flutes, the section areas get larger and the rigidity gets higher, but the chip capacity goes down owing to lessening the chip pocket and it is easily blocked up by chips.
The rigidity of tools by the length(L) of the flute
The shorter the length of tools, the higher the rigidity and performance of cutting.
The length of the flute becomes twice, the rigidity of end mills falls to 1/8. Because end mills are the tools to move horizontal, it is important for the rigidity of tools to be in inverse proportion to the length of tools. Using a longer flute that needs to be is not good.
