As a electronic guy I often need to cut 1/16-3/16" & sometimes 1/2 small pieces of Aluminum, I have a Craftsman cast iorn 12" bandsaw. They sell metal cutting blades for these all the time however I know I will have to drop the rpm. One blade has 9 tpi the other 14 tpi but neither say what rpm to run. The stock saw has 1725rpm motor 2/1 pully for 862 rpm of the 12" wheel. If i figure it right thats around 2700 fpm, again this is for wood cutting. What would be a good fpm to go for when cutting aluminum. Another thing is both say for non ferrous metals but will also cut thin ferrous metals, one 9tpi and ones 14tpi both fit the same model saw, I guessing the9tpi could run a faster fpm?
