The RotaTrim® Professional Rotary Trimmers offer a unique twin-guide rail design and nylon bearings that ensure silent, resistant-free and accurate cutting. It can be used to cut paper, film, laminated materials and digital media output from image setters and plotters. A die-cast steel housing over the cutting wheel keeps the operator safe. The cutting wheel self-sharpens the sheffield tungsten steel blade on the return pass enduring smooth, clean cuts for years to come. Each Rotatrim Professional Cutter comes with a 5 year manufacturer guarantee on all parts (excluding flat blades, clamp strips and cutting wheels).
