This is how a hammer drill works.

A hammer drill is a powerful tool that combines the functions of a drill and a hammer or chisel by using both to make it easier to finish a wide variety of tasks. But just how does it accomplish this? A hammer drill uses a rotary-percussive action to drill holes in hard materials. It works by first rotating the bit and then striking it at the end of the downstroke when it rotates fully. This is known as a ‘post-impact method.’ The technique is used in ‘percussion drilling’ or ‘hammering.’
