1. Electric hammer
Electric hammer is a kind of electric drill. Compared with impact drill, electric hammer needs the minimum pressure to drill into hard materials, such as stone and concrete, especially relatively hard concrete. It can open 6-100mm holes in hard materials such as concrete, brick and stone. Therefore, it is widely used in hard concrete, stone drilling, professional installation, engineering construction and other scenes.
Noted: the electric hammer vibrates greatly during operation, which has a certain degree of damage to the surrounding structures. And it cannot pass through the reinforcing bar in the concrete structure smoothly.
Model selection: electric hammer with speed regulating switch must be selected, so that it can start smoothly, and high speed can also be used to ensure work efficiency during normal operation; In addition, it is best to choose the electric hammer with positive and negative rotation function. If the electric hammer drills deep, the drill bit will inevitably be stuck, and the electric hammer without reverse rotation function is difficult to pull out.
2. Electric pick
The electric pick is a double insulated hand-held electric tool powered by a single-phase series motor. The power of the motor makes the pick have the effect of chiseling the ground. It has very high power. It is completely fearless of hard concrete and stone, but the pick of the electric pick does not rotate and can only dig. It is widely used in construction engineering, crushing and chiseling, excavating, grooving and cutting concrete, brick and asphalt pavement.
Note: the electric pick is an intermittent working tool. When the work is overheated, the operation shall be suspended. It is recommended to cool for 5 ~ 10min after continuous operation every 10 ~ 15min.
Model selection: Electric pick is mostly equipped by professional construction personnel, which are rarely used in ordinary families. Therefore, it is best to choose electric hammers and pickaxes, which can be used in a wider range. The anti-skid performance of the handle of the electric pick is very important, otherwise it is difficult to control the huge recoil force.
