| 31.3 | 8.69 | 59.0 | Aluminum Cutting Machine Aluminum shears cut scrap metal and help to separate different material types, earning you more money from your metals. Our shears are ideal for recycling scrap bar, tube, extrusions, car radiators, gear boxes and gate valves. We have been manufacturing alligator shears for more than 30 years. Ecohydraulic shears come in all sizes and are typically described according to blade length in mm. They can be powered by both single and 3 phase power supplies. Some shears have a diesel option. Operator safety is upper-most in mind so our range of shears are equipped with blade guards and foot-operated switches.
