A typical chop saw runs around 4000rpm.  These slower (slower) chop saws
run around 1300 which should reduce heat buildup.

Something I've noticed but haven't handled one in person is that the
motor appears to be fully enclosed on them. I wouldn't buy one that
isn't🤷️

I fix stuff for friends and family on the cheap (free) and I've had two
abrasive cut-off saws and one 4" angle grinder with shorted windings in
the armatures. They had A LOT of metal slag and crud floating around,
stuck inside the motors. Armatures are expensive. Only fixed one of
them, a Dewalt ~14 inch saw with a new armature. Even that a was big
pain in the butt. Had to mod a home made arbor press to remove some of
the bearings...
