The coarse tooth saw blade has larger teeth for aggressive cutting. It is designed for cutting wood, drywall and other soft material. This blade will cut through a few nails but is mainly used for softer applications. Almost as fast as a reciprocating saw, they can be used for cutting under the kick plate when installing new kitchen flooring, undercutting door jambs or flush cutting tongue-and-groove. They have a flush-cut design to allow the operator to lay the blades flat on surfaces perpendicular to the cut.
