Cold saws are called cold saws because they stay cold, seems to make sense but it's how it stays cold that makes it a cold saw. Traditional chop saw blades get super hot because of the friction created from their abrasive blades coming in contact with the metal, as well as the strain on the motor as it becomes harder for it to turn the blade because of the friction there. So the blade becomes hot and wears out faster, the motor consumes more power, and the piece you're working on is ultra hot and potentially warped which is especially true on alumnium and stainless steel. Cold saws don't make any of the same mistakes. First it starts with its gear reduction, giving the saw lower RPMs while maintaining constant torque so it can pull up big chips without so much as slowing down. Also cold saws use special blades made from high speed steel (HSS) or carbine tipped blades meaning they're much harder than the materials they're cutting, instead of softer like abrasive cutting blades, and because they're steel, are perfectly resharpenable.
But, where did the heat go? Technically I already explained it. The combinated of hardened blades, high torque and low speed cutting result in big 'chips' which are essentially metal that has been removed in order to make the cut. So friction is created where ever two solids are in contact, and where the blade contacts the metal it's removing that same metal and the heat created goes with the chip leaving the work piece and the blade relatively cool.
Ontop of that we flood each part with coolant so literally the blade and piece being cut are constantly cold. There's do deburring, no dust, just machine quality finish.
