Item specifies carbide teeth. I highly doubt they are hard metal. I couldn't cut a single nail while removing the window sill. The blade was so worn that the teeth were left dented by the nail. The coating has peeled off the blade so it looks like it has been dyed to look like carbide. Then I used a regular wood and metal blade and cut through the same nails. I would not recommend purchasing this product at any price due to the sheer quality of the blades.
