Cutters (Electric)
A cutter (electric) is a cutting machine that is supplied with power from a cord or battery and cuts various materials with little effort. Multi-cutters include examples with heated blades that are optimal for processing styrofoam, and examples that can cut various materials such as cardboard and carpet. All-screw cutters are dedicated for cutting threaded bolts, and are made to be suitable for upward facing work as hey are often used near the ceiling. By simply changing the blade, they are able to handle all kinds of screws. Ultrasonic cutters can smoothly cut plastic products, rubber products, and composite materials by vibrating blades 20,000 to 40,000 times per second. Electro-hydraulic rebar cutters can cut steel bars for reinforced concrete without generating fire, and a number of easy-to-use ergonomically designed products have been developed.
