Rage saw blades?

[Talonmotorsport]

Cheers guys just needed to know wether the blades where up to much use? I would have thought that a blade with that few teeth would'nt be any good for thinner gauge box section, hacking it at high speed instead of cut? My cold saw has 180 teeth and runs at 850rpm. I found some simular blades for £20-25 but as ali is more like wood from a blades point of view it might last a little longer. I'll let you know how I get on....Nurse?!
