An air hammer, also known as an air chisel, is a pneumatic hand tool used to carve stone and to break or cut metal objects apart. It is designed to accept different interchangeable tool bits depending on the job at hand, so the same powered body can be fitted with a point, a flat chisel or another attachment as the work requires. Because it delivers rapid, powered blows through compressed air rather than through a swung head, it does work that would otherwise take many repeated manual hammer-and-chisel strikes, and it is used across stone carving and metalworking wherever a job calls for that kind of repeated, controlled impact.
Facts
Introduced When (Circa) OriginOne of two pneumatic devices invented in the 1920s, the stone carver's hammer struck at two to three times the speed of the pneumatic rivet gun and was valued for smooth, rapid dressing of granite and marble; in 1930 F.J. Hauschild adapted the concept into a portable hand-held tool for straightening auto bodies. 1 Introduced era (class) In the Other Atlases

In the 1920s, two pneumatic devices were invented that would permanently change the way metal and stone were hammered.

The other new device, hitting at twice or three times the speed of the rivet gun, was the stone carver's hammer, a great blessing for smooth and rapid dressing of granite and marble.
