A jackhammer, also known as a demolition hammer, is a type of power tool used to break apart rocks, asphalt, and concrete. It can also be used to remove tiles, tree stumps, bricks, and even frozen ground. This tool mimics the up and down motion of a hammer, chipping away and breaking apart rocks and concrete with every blow.
Jackhammers are either powered by compressed air or electricity. Some are powered by gasoline, while larger models that are mounted to backhoes and excavators are equipped with a hydraulic engine. Air-powered and electric jackhammers are usually light and portable, but a pneumatic jackhammer’s hose or an electric hammer’s cord can be self-limiting. You always need to have an air compressor around in the case of a pneumatic model or have access to an electrical outlet or generator in the case of an electrical model.
The most portable jackhammers, on the other hand, are those that are powered by gasoline. These tools don’t have cords and are not attached to hoses. All you have to do is mix the right ratio of gasoline to motor oil, place the mixture inside the jackhammer’s canister, and you’re good to go.
In this review, we’re going to set aside hydraulic jackhammers, and focus on models that are powered by air compressors, electricity, and gas.
