The Excalibur 21 in. variable speed scroll saw's unique design provides a stable platform when cutting straight or on an angle. Unlike other scroll saw where the table is tilted for angles cuts, the entire head of the Excalibur tilts 45 deg to the left or the right. This allows the user to better control the work piece on a flat table surface, for more safe and accurate cut, and the covenient foot switch. Solidly built upper and lower parallel arms keep the blade straight with minimal blade deflection allowing for precise cuts. The Flexi shaft dust blower clears saw dust dust from your work area as you saw to give you precise cuts with a clear line of vision.
