Don?t let an inferior saw blade slow down your circular saw. Step up to a Dewalt Construction Saw Blade and slice through a variety of jobsite building materials, including construction lumber, plywood, OSB and siding. The contractor-duty, thin-kerf blade features extremely durable tungsten carbide teeth, which stay sharper longer than standard carbide blades. It also has a specially formulated anti-stick coating that reduces friction and sticky gum buildup, and ribbed heat vents that allow the blade to run cooler and cut quicker while eliminating warping.
