How a hammer mechanism works

This picture shows a scheme of a hammer mechanism with notched plates as it is typically used in drill hammers.

Part (A) shows the basic position of the hammer mechanism. By turning the upper notched plate, it is lifted from the lower one, thus tensioning a spring in the upper part of the machine. (B)

Further turning of the upper notched plate will cause a release of the saved spring energy. This spring energy is directly converted into kinetic energy. As a result, the drill will move forward, like being hammered while turning.

Using this technique, you can achieve a hammering frequency of up to 200 strikes/second easily.

Any questions or suggestions? Feel free to comment on this.


  1. Dass du dir über sowas gedanken machst, egal gut gemacht! ;)

  2. Not bad. But in time it looks like it will wear off. You'll start losing hammering power eventually.

  3. das ist sehgut! lol thats all the german i know but this stuff is crazy right here!

  4. holy crap really 200 hz? that must be a really loud drill
