These E-Cut blades have a Japanese pull-saw tooth pattern for a very aggresive cut. They are designed for cutting wood, plaster, drywall and other soft material.
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. Avoid materials that might include nails.
