What are the impact mechanisms of down-the-hole drills

A is first thought to have been used for rock drilling in 1844. Many quarries used hand held tools that required the driller to suspend himself from a rope over the quarry face in order to place the drill hole in the required position. This system used small diameter holes and was not only terribly inefficient, but very dangerous due to flying rock as a result of the inaccuracy of the drilled borehole. The hammer directly strikes the drill bit, creating a powerful impact that allows for efficient and precise drilling.
