Kapex blade for aluminum?

Try Amana, CMT, Diablo, Freud, Tenryu or Evolution for starters. I have the Festool blade and it’s really nice.
 
Hi, not a whole of cuts made but oshlun for 65$ has been great, good reviews as well.
 
Almost as important as the blade, aluminum cutting lube will make a significant difference.

In the olden days, they used a white stick that they would call “hog grease”, and it probably was as when my German Shepherd got a whiff of it he went crazy.

I think they use synthetics nowadays. But use something, it makes a difference.

I have no specific recommendations, but take a look here:
