Yes, the mesh part can block up to 75% of the air going through.

And what are the size of those fans, and where? They look like 140s.
lol...nevermind, you said 120s. They look bigger than normal though, for some reason.
They are compound action action tin snips (notice there are 2 pivots, it makes them cut very thick material)
The ones I have are from Wiss (one of the best) I have had a pair for 30 years and they still cut good. The red handle ones are designed to cut straight and left hand circles. They have them at HomeDepot for like $14.
The fans look big because the motor assembly (center section) is smaller to permit more airflow. Those are the scythe ones, Silenx fans are similar as well.
I like Dremels too, BUT they cost just way too much to use to make big cuts
