A jackhammer is an electro-mechanical or pneumatic tool that combines a chisel and a hammer. While most hand-held jackhammers are powered by compressed air, some actually use electric motors. They are most commonly used to break up concrete, pavement, and rock, and were developed in the 19th century as a response to the needs of tunneling, excavating, quarrying, and mining.
For the best overall jackhammer, you can’t go wrong with Bosch, particularly the Bosch 11335K 35-Pound 1-1/8-Inch model. It weighs close to 38 pounds, and the all metal housing allows it to stand up to even the most difficult conditions. Bosch carries all types of breaker hammers, rotary hammers, demolition hammers, and chipping hammers. For a great pavement breaker, check out the DEWALT D25980K model, which is a corded electric jackhammer with 61 feet/lbs of impact energy. It is one of the best performance jackhammers on the market.
Before you start working, make sure you have all the necessary protective gear, such as earmuffs and safety goggles. Plug in the jackhammer, and position the jackhammer over the surface that you wish to break. You will want to use a prying motion to force the concrete, or whatever surface you intend on breaking, upwards as the jackhammer cuts into it. When the jackhammer loosens a large chunk of material, break the chunk into the smaller pieces, and then remove them from the job site. This will give you a clean area to work with, and allow you and the machine to rest for a short period. When you have finished, turn off the jackhammer f and unplug it.
Safety Features & Guidelines
Jackhammers are designed to break rocks, concrete, and asphalt, and thus are extremely powerful. Without proper protective equipment and training, workers can easily injure themselves while operating a jackhammer. There are several safety guidelines you can follow to help prevent injury. Always wear eye protection, steel-toed boots, long-sleeved clothing, and safety gloves. You should also wear ear protection because the machine can get very loud. Inspect the jackhammer for any defect or damage before you start working, and always use the proper type of jackhammer for the job. Make sure to operate the tool at a slight angle to prevent the point from getting stuck in the material. This will also allow you to control the jackhammer more easily. You should also barricade the work area as much as you can to prevent people or animals from wandering into the job site.
Pros & Cons
Using a jackhammer is a quick, efficient way to break-up concrete or cement. It is much easier to use at a large job site as opposed to a sledge hammer, which is better for smaller jobs.
Jackhammers can be dangerous if the person operating the machine doesn’t know how to, however, so always make sure you have someone who knows what they are doing working with the jackhammer. This can help prevent injury or other potentially dangerous situations from arising. Jackhammers are also heavy, and it can be a strain on your body, particularly your arms, if you have to use one for an extended period of time.
