"When the blade is new it's amazing, cuts through mild steel very well indeed. However after a few cuts the blade starts to dull and it ends up cutting less cleanly with more mess. The blades are expensive so it's not an economical way of cutting steel in the long run. Oh and when the blade's dulled a bit, don't try to cut aluminium! It'll weld onto the inside of the teeth and it's £55 for another new blade.
The main problem I think is because the saw spins too fast. If it was half the speed the blade would last a whole lot longer and do just as good a job. I know they make it this fast so it can cut a variety of materials but honestly for wood I'd rather a mitre saw anyway.
The powdercoating also wears off too easily. Good idea in theory, I'd recommend it over an abrasive chop saw I guess but for cutting steel on a regular basis a cold saw or a bandsaw will work out cheaper in the long run."
