Percussive Drill

The neighbors next door have been doing a few "minor renovations" for about a month now. Before, the loud noises came from drills and clanking ladders and stools. But now, they've brought in the jackhammer to chisel it's way through the house. A jackhammer is a pneumatic tool that combines a hammer directly with a chisel. 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. The effectiveness of the jackhammer is dependent on how much force is applied to the tool.
