A Single Bevel Mitre Saw has a saw head that only tilts (bevels) in one direction. A Double Bevel Saw can rotate both left and right, about the vertical plane, to make bevel cuts on both sides without having to flip the workpiece.  A Double Bevel Mitre Saw provides greater versatility and precision. These saws are ideal for making complex, decorative cuts on intricate work, such as crown moulding where cut angle precision must be exact in both directions.
