Hey Guys, I never understood the difference and what application should one use over the other.
An abrasive cutoff disk is similar to a grinding wheel, and exposes new grit as it wears. Downside to these is that they wear quickly.

The metal cutting saw blade is like a regular carbide blade with tooth geometry optimized for steel. The last a lot longer, and cut much cleaner.

so why would one use an abrasive cut off wheel if a carbide blade last longer and cuts much cleaner?
Abrasive wheels will cut harder metals like cast iron. The blades are thin and will make radius cuts better. They are also cheaper.

Just a different tool for a different application.

Because the abrasive cutoff wheels are much cheaper. If you only have a few cuts to do, this is the way to go.
