1. Jackhammer

   A jackhammer (pneumatic drill or demolition hammer in British English) is a pneumatic or electro-mechanical tool that combines a hammer directly with a chisel. It was invented by William Mcreavy, who then sold the patent to Charles Brady King. Hand-held jackhammers are generally powered by compressed air, but some are also powered by electric motors. Larger jackhammers, such as rig-mounted hammers used on construction machinery, are usually hydraulically powered. These tools are typically used to break up rock, pavement, and concrete. A jackhammer operates by driving an internal hammer up and down. The hammer is first driven down to strike the chisel and then back up to return the hammer to the original position to repeat the cycle. The effectiveness of the jackhammer is dependent on how much force is applied to the tool. It is generally used like a hammer to break the hard surface or rock in construction works and it is not considered under earth moving equipment, along with its accessories (i.e., pusher leg, lubricator). In British English, electromechanical versions are colloquially known as "Kangos".

1. Jackhammer

   A jackhammer is a pneumatic or electromechancial tool that combines a hammer directly with a chisel. It was invented by Charles Brady King. Hand-held jackhammers are typically powered by compressed air, but some use electric motors. Larger jackhammers, such as rig mounted hammers used on construction machinery, are usually hydraulically powered. They are usually used to break up rock, pavement, and concrete. In modern terminology, a "jackhammer" does not have the capacity to drill rock. A jackhammer operates by driving an internal hammer up and down. The hammer is first driven down to strike the back of the bit and then back up to return the hammer to the original position to repeat the cycle. The bit usually recovers from the stroke by means of a spring. The effectiveness of the jackhammer is dependent on how much force is applied to the tool. In British English electromechanical ones are colloquially known as "Kangos".

Examples of jackhammer in a Sentence

1. Joseph Janik:

   Some days he comes in and hes been on the jackhammer for six hours, and hes beat, so we have to adjust the training. Its definitely not ideal. Id much rather if he got up and had a latte, did some Pilates and some cryo(therapy) and then came to the gym. But he likes it. He likes the guys that he works with. I think it helps keep him focused, and he appreciates his moments in boxing even more.
