The difference between the electric hammer and drill.
A hand drill used only for rotation without axial impact; used to drill holes in metal material;Impact drilling has both rotation and axial impact motion. It is commonly used to drill holes in brick concrete and rock;Hammer, is more impact drill.
The drill operation is stable, operation of large vibration hammer. Something that is not too hard, such as metal, wood, plastic, etc.. The electric hammer drill are hard or easy to hurt a bit, drilling is generally like concrete.
In other words, hammer beating and smashing finish tasks with the forward shock action, and the drill is along the axis of rotation to complete tasks such as scraping and drilling.
The difference between electric is the former along the extending direction of the impact hammer line work, the latter is to rotate along the axial direction of the drill bit.
