A plain tooth, also known as a regular tooth or standard tooth, is a tooth geometry found on band saw blades, characterized by a straight, uniform profile, a 0-degree rake angle, and evenly spaced teeth. Plain tooth blades are designed for general-purpose cutting and provide a balance between cutting speed and surface finish. They are suitable for cutting a wide range of materials, including wood, plastic, and metal. However, they may not perform as well as specialized tooth geometries in certain applications.
