Mitre Saw recommendation for cutting Aluminum Profiles / Extrusions

Good day gentlemen!

I do have quite a bit of Aluminum Profiles / Extrusions from my project left over.

I would like to seek your kind recommendations with a good mitre saw / blade / model / cordless for one to cut these in to precise and clean cut for my home storage rack.

And i would like to also do a proper tapping of the extrusions like M6 / M8 screws , what should i do it with? A hand drill with tap or maybe a bench drill?

Any comments are welcome! Thank you!
