The type of blade & saw are called a
dry cut chop saw as opposed to an abrasive cut chop saw. The motor RPM is roughly half that of an abrasive saw, and the blade is carbide-tipped.
Makita, DeWalt, Milwaukee, Hitachi, Jepson, etc., all make their version - all are pretty much identical except for color
They all claim phenomenal blade life
which is true if you cut what they were designed to cut - gauge thickness metals & thin rounds. Start cutting larger material (like the 3" solid that was mentioned) and you might get 100 cuts per blade.
I bought the DeWalt Multicutter when it first came out & sold it a couple of years later - it was replaced by a wet-cut horizontal bandsaw. Quite a few reasons I didn't like it:
Tiny footprint (like all chopsaws). Easy to tip.
Very light construction.
Universal motor (brush type) means limited motor life.
Expensive blades that don't last nearly as long as claimed.
Noise level much like an F15 Eagle at takeoff with both engines on full burner.
There are, however, quite a few people who like them. For me, the cost per cut was the final straw - probably ten times higher than a wet-cut band saw.
