We sell a version of this at my work. The chop saw that was mentioned earlier was most likely a Milwaukee. Model number is 6190-20. As seen here:

The machines are specially designed to work with these blades, they are low RPM (the circ saw is about half of normal 7 1/4 in circ's), high torque motors. I used the circ saw to cut out my 3/16" steel floor for my K5. It took me about 45 minutes to measure and cut. I didn't have to buy it, cause I "demo-ed" it from the Milwaukee rep
The blades have carbide tipped teeth, which is what stops sparks and allows it to cut cool. It really leaves a nice finish, but as was mentioned, enough torque and ripping power to leave you limbless if you're careless.
It will cut through 1/4 steel all day long. Any thicker and you have to run it a certain distance, and then let it cool, either sitting or run it with no load for 1 minute.
Great product, it works amazing. If anyone wants more information, just post here.
