Gosh - I've been using a radial arm saw to cut FR4 PCB material for at
least 20 years. The blades are 10" carbide with 60 or more teeth. Nice
clean cuts so long as the blade is sharp - which is quite some time. I
don't have hour figures at hand but I have half a dozen blades (all used
for different purposes) that I get sharpened about once a year.
The bi-metal blades for my Bosch jigsaw work OK as well and seem to be
fairly long lived.
I currently use the saws to cut 3' x 4' panels down to the size my 30"
shear can handle. Before we had a shear, we used the radial arm saw to do
all the cutting. Although the radial arm saw is noisy and dangerous, it
had NO problem cutting all the PC material we threw (and throw) at it. A
table saw with a nice, sharp carbide tooth blade and a fence that is
accurately aligned should work just as well.
