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.
