Dry Driling Machine are commonly used to secure long bolts or screws into wood, metal, and concrete, as well as loosening ceased or over torqued bolts. Impact drills come in two major types, pneumatic and electric and vary in size depending on application. Electric impact drills are most often found cordless and are widely used in construction, automobile repair, and fabrication.

Dry Driling Machine preferred over the pneumatic driven because of their maneuverability and ease of use.

The chuck acts more as a collet with a hexagonal shape in which the bits and drivers lock into.
