A higher BPM will allow you to get your work done much faster, and many times it can make up for a lower impact force by delivering more blows against the concrete. Beats per Minuteīeats per minute is a measure of how many times the chisel hits the ground in one minute, and it’s directly related to the strength of the engine. Companies list impact force in foot-pounds, and we recommend purchasing a unit that delivers at least 25-ft/lbs of impact force.
Higher values equate to a stronger engine, allowing you to smash up denser material and thicker concrete. Impact ForceĪnother way you can determine the motor’s strength is by checking the impact force delivered by the tool. We recommend a jackhammer rated at least 1,200 watts or 12 amps, which all the brands on our list achieve. When comparing two brands, higher values equate to a stronger motor. Most models will have one or the other listed on the package though some may have both or neither. When looking over the packaging, one way to figure out the motor’s strength is by looking at the amp and watt rating. We recommend an extension cord no smaller than 12-gauge to avoid an electrical hazard. You measure wire thickness by gauge, and extension cords are available in 10, 12, 14, and 16-gauge sizes. When purchasing an extension cord to use with your electric jackhammer, it’s important to get one that can handle the amount of electricity it needs, or it can get hot or even create an electrical hazard. Some of the jackhammers on our list have extremely small cords, and you will need to purchase an extension cord to get any range. The cord is also in an awkward place, and it tends to leak a little oil. We’re sure this flexibility will result in a broken handle down the line. The biggest downside of the XtremepowerUS Electric Demolition Jack Hammer was that the handle is not very sturdy and flexes quite a bit while you are using it. It also comes with an impact-resistant case, gloves, protective glasses, and a protective mask to help keep you and the tool safe. It includes a 16-inch bull point chisel and a 16-inch flat chisel so you can get started at once. An adjustable 360-degree foregrip allows you to use the machine at the most effective and comfortable angle. It features adjustable speed, and an anti-vibration system minimizes fatigue while you are using it. It is lightweight at just 45 pounds and is well balanced and easy to control. It uses a 2,200-watt motor to deliver 55 ft/lbs impact force at a rate of 1,800 BPM. The XtremepowerUS Electric Demolition Jack Hammer is our pick as the best electric jackhammer for the money.
