What's the difference between a drill and an impact drill?
In relatively hard walls or concrete drilling must be impact drilling, drilling on a hard material, electric drill can be pulledThe drill bit of the percussion drill is telescopic and is punched before and after drilling

If you use ordinary drill in drilling stone or concrete, ordinary drill blade will soon be blunt to scrap, and rotation is the impact of improving the drilling efficiency.
An electric drill can drill holes in various metals, woods, plastics, etc.. Because of stone, brick, concrete is hard and brittle properties of metal and bit strong wear on these materials requires the use of drilling drill, drill hammer (hammer) inlaid with hard alloy with high hardness, impact drill impact and rotation (as with the drill rod drill in as the rock), while on one hand, the stone became a little bit to be cut down into a hole.
The only force flat rotary electric drill, impact drill and rotary force (hammer) in addition to one axial vibration force.
