Electric disc cutters are usually lighter, more compact and easier to handle than petrol ones, making them a better choice for general work and projects that require more precision. They also produce less noise and emissions than petrol disc cutters, making them more environmentally friendly. Electric disc cutters also provide instant torque at all times and don’t require revving up to start a cut.
Petrol powered disc cutters use a fuel and oil mix that requires mixing before use, they produce more noise, exhaust fumes and are usually heavier and larger that electric disc cutters. They do provide the ability to be used in places where there is no power and the largest petrol models can provide more power than their electric counterparts.
The choice between electric or petrol power will come down to many factors such as power, cost, weight, ease of use and the type and size of job.
