Do you all use cutting fluid when you cut thick chunks of aluminum on your 4x6? I imagine the blade life is longer wet? Messier to clean up though

I have used cutting oil, which really needs blade wipers to keep the chips out of the guide bearings and the wheels. I also have used some left over cross country ski wax, those _wood_ x/c skis with cable bindings have not seen use in decades, nor the bamboo poles and the leather boots. The ski wax is soft and works well, and I have at least half a dozen tubes of different ones with varying hardness for different snow conditions, will probably last me a life time on my saw. Klister waxes might turn out to be a mess, about like very thick honey at room temperature

I bought a 4 inch carbide saw blade at Menard's and it works great as a slitting saw or for 3/4 inch or less material on aluminum.
I have been sawing with it dry. Blade thickness is about .050 I think. Price about $9. I have been
using 100 rpm or so and it seems to do fine with a slow feed rate. I havn't tried it on mild steel yet and probably won't.

Amen on the Wax stick. I use it on the band saw, hole saws, and pretty much anything with saw teeth., including hack saws.
I like DoAll, Castrol and Walter Tech. wax sticks.

Wax sticks work great , I've also used my mister if I don't want to sit over the saw.

Unlike most responding here I cut aluminum dry. I use a Startrite H175 vertical/horizontal band saw. The saw has coolant capability, but I never use it. Most often I use a 10-14 tpi variable pitch bimetal blade .035 thick at 80 fpm. The down pressure is set at 6 psi. The saw also has a circular wire brush just beyond the exit side blade guide. The blade stays clean and will easily cut through a 3" x6" block without more than a couple thousandths variance from top to bottom.

Depending on the use and materials I usually get 2 or more years from each blade.

Without it, everything just stops cooperating
