Why the Double Cut Provides Exceptional Smoothness and Control

Imagine rubbing sandpaper in two directions rather than one – it smooths rough spots more efficiently and reduces vibration. This effect not only leaves a cleaner finish but also helps you steer the tool with precision, so you can shape your workpiece exactly as planned without unexpected skips or chatter.
