The twin-guide rail design and nylon bearings on the Rotatrim trimmers ensure silent, resistant-free and accurate cutting. Versatile and affordable, the Professional Rotatrim is used extensively for cutting 12" to 54" film, laminated materials and digital media output from image setters and plotters. An ergonomic die-cast steel housing over the cutting wheel ensures the operator is safe. Its cutting wheel self-sharpens the sheffield tungsten steel cutting blade on every return pass - making for smooth, clean cuts every time.
