Just purchased the 120. Is the standard blade ok to cut Aluminium 20/80 or do I need to invest in the Specific Al cutting blade. I only need to do a half dozen cuts?
I don't recommend trying to cut non ferrous metals with the standard kapex blade. You risk kickback and other horrible things. You'll need to invest in a TCG Triple chip grind blade which is a more shouldered tooth. You can use the blade for laminate, lexan, Plexiglas.
I buy my blades from Toolstoday......................Amana/AGE, in the past I've bought industrial blades fro Freud. Amana's Blukote blades are amazing, I no longer use WD-40 as a lube unless I'm cutting 3/8"+ aluminum.
