Demolition hammer is another name for jack hammer (In some countries and regions, it also written as jackhammer), which is also called demolition breaker. Demolition hammer combines the functions of hammer and chisel. Match with different bits, chisels, shovel, it can be used for drilling, concrete/stone breaking, wall digging, tile removal, etc.
Although electric jack hammer is a hand-held power tool, it is usually heavy-duty, the weight of the whole machine can reach 5kg, 10kg, or even 16kg. Its price is also more expensive than ordinary electric hammer.
Demolition Hammer Working Principle
Electric demolition hammer performs hammering action by driving the hammer inside it to move up and down. The hammer is first driven downward to strike backward, and then lifted backward to return the hammer to the original position and repeat the cycle. Hammering effect of electric demolition hammer depends on the amount of force applied.
Where to start hammering is important to the effectiveness of demolition hammer. When working on the floor, start from the edge. If you start from the center or corner, as the debris gradually accumulates, it will cause problems in later operations. It would be better if the work could be done from the inside to the outside, because the debris will be closer to where it is needed and can be easily removed. When working on a wall, start as close as possible to the center of the wall and chisel down. The weight of the top load will cause the concrete to fall on its own.
Placement of the demolition hammer tip directly affects hammering effect. If the demolition hammer lip is pointed straight down or pointed into the surface to be removed, it will cause the hammer to hit the same position continuously, which will only create a hole at that position. The trick is to tilt the drill bit of demolition hammer and point downward. In this way, the lip will chip into the material instead of passing through it.
