Maximize your efficiency with this 51-inch Dahle premium rotary trimmer, which can cut up to 30 pages at once. The self-sharpening circular blade keeps a perfect cutting edge, so you don't have to worry about rough spots or annoying burrs on your cut pages. The blade works in both directions, and it is enclosed in a protective plastic covering for safety. Because it's designed for heavy duty use, this trimmer can handle thicker materials, such as mat board, with ease. An aluminum guide rod and pre-printed surface ensure that your finished pieces come out exactly the way you want. You can use this trimmer on any flat surface, use an optional mounting stand or mount the trimmer on a wall to save space in your office or studio.
