Ready for another Saturday night silly question?
What is the difference between a ferrous and non-ferrous circular saw metal cutting blade? I know the difference between the two metals. I have a small Makita 5-3/8" cordless metal cutting circular saw. I have 30-tooth and 50-tooth blades but they both say they are for ferrous metals. Looking on-line I see that most blades are advertised as being for ferrous but a few are in fact labelled as non-ferrous. Both style blades come in 30T and 50T and are carbide tipped. So what makes one 30T or 50T carbide blade suitable for non-ferrous and another one not?
I have to make a 6-inch cut through 1/4-inch thick 6061 Aluminum Tooling Flat Sheet Plate Bar Mill Stock and I'm trying to decide if I can use either of the blades I currently have.
