The Challenge Spartan 150SA semi-automatic paper cutter is similar to the Spartan 150M but a little more feature-rich, with more room for cutting. The 9 inches in front of the cutting blade gives you a little more space than the 150M cutter's 6 inches. The manual hand crank wheel clamping system supplies more force than lever systems, helping you achieve sharp, precise cuts every time. The manual clamp, combined with the cutting line and precision LED digital back gauge position indicator, produce the best cuts. The auto-release front shield opens after the cutting is completed, which makes retrieving your paper virtually effortless. There is also a safety cover on the rear table. The dual cut buttons require both of your hands, protecting them during operation. This paper cutter proves to be long-lasting, with steel and cast iron construction and bronze bearings on the majority of the wear surfaces. The Challenge Spartan 150SA cutter is highly suitable for a number of work environments, including offices and copy centers.
