I ordered some of their 3 flute variable helix end mills for aluminum for use on a CNC mill, and they rock. They clear chips just as well as 2 flutes, but cut soooo smoothly, and leave perfectly formed chips and a great surface finish.

They're ~$35 for a 1/2" end mill which may be expensive depending on what kind of tooling youve been purchasing, but they're a great deal for us, since the previous 1/2" end mills I've been purchasing were ~$45 for 2 flute TiN coated carbide.
