I bought this saw for residng a garage with Hardy Plank. When I received the saw it had a standard carbide blade. Amazon.com customer service was very nice and shipped out another saw. It too shipped with a standard blade. I ordered a $59 Hardy blade because I needed it and they gave it to me for no charge. What a difference it made using the hardy blade. Less dust, quieter, and very smooth cuts.Get more detail about Hitachi C7YAH 7-1/4-inch Dust Reducing Circular Saw with PCD HardiBlade.
