The adjustable Angle GD-900H is suitable for the processing of the workpiece with the size above the cigarette box, and the non-adjustable Angle GD-900 is suitable for the small workpiece below the cigarette box. The adjustable GD-900 working plate has a hole in the middle of the cutter to facilitate the adjustment of the Angle, so the workpiece smaller than the cigarette box is not safe when sliding.
