A jackhammer is a powerful tool used for breaking up hard surfaces like concrete or asphalt. It works by using rapid, repeated impacts to chip away at the material, making it easier to remove. Construction workers often use jackhammers for tasks like road repairs or building demolition, as they can save a lot of time and effort compared to manual tools. These machines are typically heavy and require some strength to operate, but they come in various sizes. Some smaller models can even be used by homeowners for DIY projects. Safety gear, such as ear protection and gloves, is essential when using a jackhammer to prevent injuries from noise and vibrations.
