I've been having opportunity to cut a variety of materials lately,
and have found that the high speed of the saw with a bi-metal blade
can cut steel (low carbon or small chunks of O1), brass, and aluminum
with no visible ill-effects.
Also...since I haven't gotten my motor replaced or fixed or anything,
and I'm still having to add weight to the saw to cut less bumpily, I
used a dumbell with threaded collars and hooked it onto the hand
guard. I added a 2.5# plate to it, and the blade is contacting both
rear bearings now while cutting. Looks odd, but works well.
