It sure looks like a variety of concrete cutting chain. They are generally diamond impregnated and can cost $$.

40-60 linear feet of 6”. Concrete is its lifespan

what does one use something like that for?

 

[Steve Connally]

I was gonna say concrete. We had concrete saws on out Heavy Rescue Collapse Trailer. Sometimes those work better than the circular. Pretty messy though. Cut like a champ

I once had a fellow tell me they're carbide and also used to cut square corners openings in concrete chambers or vaults when circular blades can't. Sure play hell on the bar! Water feed? Oil? Surely not dry. Diamond make sense for durability, but concrete drill bits are just carbide.
