The Dahle 14" Rotary Trimmer is designed for professional use and is indispensable in advertising agencies, graphic design and photographic studios, as it gives a burr-free cut on thick medium materials. Its features include ground upper and lower steel blades along with an automatic paper clamp. The rugged base helps maintain its stability while the clearly marked surface grid gives you precise registration points. Safety is ensured by totally enclosing the blade in a plastic housing. The cutting table pre-printed with reference grid lines and the adjustable backstop fits either side. The scale bar calibrated in both inches and centimeters and the entire unit can be wall mounted.
