aluminum 5/64 thick
I found it hard to saw, a lot of flapping, the blade grabs the material real easy.
used some #0 blades special for iron to cut in the A and M.
only on the A I wasted 5 blades
as soon as I went back a little and turned it just a fraction the blade snapped.....
but Mikes FD-UR #2 and #3 blades cut like a hot knife trough butter!
