2019426&ensp·&enspthe hss end mill isn't the limiting factor on your machine it's the low spindle speed and limited feed rates that the average human can produce. like i said if you're trying to cool and lubrie the end mill you're better off setting up a mist/fogless coolant system.
2019102&ensp·&ensp machiningcloud inc. end mill materials 7 end mill materials end mills are made out of either cobalt steel alloys (known as high speed steel or hss) or from tungsten carbide in a cobalt lattice (shortened to "carbide"). high speed steel (hss): provides good wear resistance and costs less than cobalt or carbide end mills.
20191028&ensp·&enspend mills for aluminum are often available in either 2 flute or 3 flute styles. with higher flute counts it would become difficult to evacuate chips effectively at the high speeds at which you can run in aluminum. this is because aluminum alloys leave a large chip and chip valleys become smaller with each additional flute on an end mill.
yes it may cost 2050% more but a coated end mill will last 35x longer than hss (and many "carbide" end mills). most coatings also have a finer grain size and nicer molecular properties than the "solid carbide micro grain" material they coat they are "slipperier" than uncoated end mills.
20191028&ensp·&enspmany configurations of single end and double end hss end mills with a variety of flute configurations are available. high speed steel tooling is an economical product used in many machine tools not equipped with the latest technologies.

if a person just grabs a cheap end mill and runs it at whatever rpm the mill happens to be set at then they shouldn't expect it to work properly or last any length of time. here's my rules of the thumb for settings feeds and speeds for both hss and carbide endmills. 6061 aluminum 400 now for uncoated carbide tooling multiply those sfm
