A plunge cut is when you cut right into the middle of the material. This is particularly convenient with the DSM20, since its cutting wheels do not have teeth, but abrasive grit, ensuring a smooth dive into the material. In addition to that, the spring loaded foot helps you to plunge cut into the material precise and safe. Flush cutting is possible with the DSM600 Multipurpose Cutting Wheel. This special accessory is an offset wheel with dome shape allowing you to cut at surface level. A rip cut is a straight cut-off of a piece of material, usually parallel with the grain (in wood).
