Single end 4 flute center cut end mill made from premium submicron grain carbide. Used for finishing operations. The 4 flute design allows for a high feed rate as less material is removed per flute. Ideal for milling, slotting, profiling and trace milling.

If greater swarf removal is desired, consider one of our 2 flute end mills.

Chris' Tips
Conventional wisdom is that 2-flute end mills are used on aluminum, while 4-flute end mills are used on steel and brass.

2-flute end mills are used on aluminum because aluminum is easy to machine and you can take big cuts. Two-flute end mills provide a lot of room between the flutes for the big chips produced when making heavy cuts.

4-flute end mills can produce a slightly better finish at the same cutting speeds because there are twice as many cutting edges, each taking off half as much material. But again, if you are not trying to maximize production, you can simply slow the feed rate with a 2-flute end mill for the same effect.

End mills are also classed as "center cutting" or "non center cutting". With a center cutting end mill, you can plunge the end mill into the work as you would a drill. This is important if you are cutting a slot that does not extend to the edge of the part. Center cutting end mills are easy to identify. If the flutes meet in the middle of the end of the end mill, it is a center cutting end mill. In some cases, one of the flutes will be longer, reaching right to the center. If the flutes stop short of the center, leaving a space with no flutes in the center, it is a non-center cutting end mill.
