The difference between hammer drill and electric drill

A hammer drill is specifically designed to drill into hard surfaces like masonry, concrete, and stone. It has a piston mechanism that quickly slams the drill bit into the material, providing a hammering action that is necessary for proper drilling. An electric impact drill is a drill that uses electrical energy to produce torque and rotation that are used to power bit tools for drilling or driving. It is mainly used for drilling into softer materials like wood and metal.
