I had the idea to ask chatGPT Is the Einhell TE-SM 2131 Dual miter saw suitable to cut aluminium? and it answered "not suitable..., only for wood and plastic..." I asked again Why is the Einhell TE-SM 2131 Dual miter saw now suitable to cut aluminium? (Misspelling NOT by NOW, whyever!) and it answered THIS The Einhell TE-SM 2131 Dual miter saw has been upgraded to include a special blade designed specifically for cutting aluminium. This blade is made from high-grade steel and has a special coating that helps to reduce friction and heat build-up when cutting aluminium. The blade also has a special tooth design that helps to reduce the risk of chipping and splintering when cutting aluminium. (OMG, I felt like we are all forked...) Asking again with NOT gave The Einhell TE-SM 2131 Dual miter saw is not suitable to cut aluminium because it is not designed to handle the heat generated when cutting aluminium. Aluminium requires a special saw blade with a high tooth count and a high speed motor to prevent the blade from overheating. The Einhell TE-SM 2131 Dual miter saw does not have the necessary features to safely and effectively cut aluminium. Okay, so AI plus NI lead to my conclusion: Exchanging the standard blade by a HMS blade with high tooth count (60+?) designed to cut aluminium and it will be okay.
