Akiles’ biggest corner rounder, the Diamond 7 can cut through 700 sheets (of 20lb paper) or 2.75″ at once. Metal guides keep large quantities of paper neatly aligned for the cleanest cut while the protective safety cover prevents any potential user injuries. Simply stack paper against the guides and easily round corners. Choose between operation modes of automatic foot pedal and manual hand operation (with a switch). Manual or automated, the Diamond 7 will deliver the perfect trim every time. And just in case of emergency, users can stop the Diamond immediately. As an exclusive feature of the Diamond 7, the detachable pressing bar holds tall paper stacks in place and is easily removed for easy replacement of knives. The patented upper die design is paired with a micro-adjustable lower die for easy cutting. The large work table comfortably holds many paper dimensions as to not compromise the accuracy of the cut. A handy built-in bin holds tools, and clean-up is made easy with the scrap collecting bin. The Diamond 7 comes standard with a 1/4″ die but there are up to 7 available dies – 1/8″, 3/8″, Straight, Half-Moon. 1/2″ and 5/8″ dies must be special ordered. The Diamond 6 handles slightly smaller stacks than the Diamond 7. The Diamond-5 is smaller but still a heavy duty trimmer. The only manual corner rounder, the Diamond-1 is also incredibly compact, and still delivers a quality cut.
