Review on SpeTool 5Pcs/Set Flat Nose Double Flute Carbide End Mill 1/32" Cutting Dia Router Bits Cutter CNC Machine Tools For Carbon Steel Soft Alloy Steel Die Steel Tool Steel Cast Iron Wood by Kyam Deriphonse

The cutter performed really poorly under my normal aluminum cutting feeds and speeds. The flutes seem oddly small and quickly clogged with aluminum.I would have given it one star, but I didn't go searching for a set of parameters that might make it happy. I'm not really interested in having a 1/16 end mill that requires entirely different parameters than my other 1/16 end mills.
