Yes, I was just bragging about cold saw we have. I only spins at about 30 RPM and has a water based flood cooling system. It is not a carbide blade. It is high speed steel and cost about $100.
We regularly cut 1/4" 6061-T6 sheets on a standard 10" table saw with a carbide tipped blade. You can get an equivalent blade at the Home Depot for less than $20.
I also have a 14" abrasive cutoff saw that I got from Lowes for $25 (beat up missing parts). I does a good job cutting steel square tube and rebar, but I would not cut aluminum on it. It would make a horrible cut. A friend tried an abrasive blade on his chop saw with steel. The sparks and heat started to melt the plastic insert and almost started a fire in his dust bag.
