Difference between hammer drill and electric hammer
A percussion drill works by rotation and impact. A single shock is very slight, but a frequency of more than 40,000 shocks per minute produces a continuous force. Percussion drill can be used on natural stone or concrete. However, the impact drill uses the gears on the internal shaft to beat each other to achieve the impact effect, and the impact force is far less than the electric hammer. It can also drill reinforced concrete, but it is not very effective.
1. Different nature
Electric hammer: Electric hammer is an electric rotary hammer drill with a safety clutch attached to a pneumatic hammer mechanism. Percussion drill: Percussion drill relies on rotation and impact to work. A single impact is very slight, but an impact frequency of more than 40,000 per minute produces a continuous force. Can be used in natural stone or concrete.
2. Different principles
Electric hammer: The principle of electric hammer is that the transmission mechanism drives the drill to do rotating movement at the same time, there is a direction perpendicular to the rotary head reciprocating hammer movement. The electric hammer is driven by the transmission mechanism to drive the piston in a cylinder reciprocating compressed air, the air pressure cycle change in the cylinder drive the hammer in the cylinder reciprocating to hit the top of the brick, as if we hit the brick with a hammer, so the name of the electric hammer.
Hammer drill: When the hammer drill is working, there is an adjustment knob at the drill chuck, which can be adjusted in two ways: ordinary electric hand drill and hammer drill. However, the impact drill uses the gears on the internal shaft to beat each other to achieve the impact effect, and the impact force is far less than the electric hammer. It is not suitable for drilling reinforced concrete.
3. Different uses
Electric hammer: Electric hammer is a type of electric drill, mainly used to drill holes in concrete, floors, brick walls and stone. Professional in the wall, concrete, stone above the hole, as well as multi-functional electric hammer, adjusted to the appropriate position with the appropriate drill can replace the ordinary drill, the use of electric pick. The advantages are high efficiency, large aperture and long drilling depth.
Impact drilling: mainly suitable for impact drilling on concrete floors, walls, bricks, stone, wood and multi-layer materials; In addition, it can drill and tap on wood, metal, ceramic and plastic, and is equipped with electronic speed control equipment for forward/reverse functions.
