1. What’s the difference between HSS and (T)CT saw blades?

    The most common types of circular saw blades are HSS, made of high-speed steel, and (Tungsten) Carbide Tipped, with very hard metal (HM) tooth tips.
  2. The advantage of HSS blades (1) is that they make a very clean cut.
  3. Carbide Tipped blades (2) give a good cutting result and stay sharp up to 5 times as long.
