Electric Hammer Drill relies on rotation and impact to work. The impact drill can be used for natural stone or concrete. Compared with percussion drills, electric hammers require minimal pressure to drill into hard materials such as stone and concrete, especially relatively hard concrete.
If the general percussion drill is 6-700W, the size of the hole that can be drilled depends on the size of the matching drill bit. Generally, the maximum diameter is 5 cm. The impact drill relies on rotation and impact to work. A single impact is very slight, but the impact frequency of more than 40,000 per minute can produce a continuous force. The impact drill can be used for natural stone or concrete. The electric hammer works by rotating and beating. A single beating force is very high, and has a beating frequency of 1,000 to 3,000 per minute, which can generate a significant force. Compared with percussion drills, electric hammers require minimal pressure to drill into hard materials, such as stones and concrete; especially relatively hard concrete. Under normal circumstances, percussion drills cannot be used as electric drills. One is that the direction of the percussion drill is not easy to grasp when in use, and it is prone to misoperation, and the opening is too large; the other is that the drill is not sharp and the hole is not neat. Burrs or cracks appear; Third, even if there is a switch on it, try not to use it for drilling, unless you use a special drill bit, but because the speed of the electric drill is very fast, it is easy to make the hole black and make the drill hair hot. Thereby affecting the service life of the drill bit.
The electric drill simply relies on the motor to drive the transmission gear to increase the strength of the drill bit to rotate, so that the drill bit is in metal. Wood and other materials are made to make holes in the form of scraping. When the percussion drill is working, there are two ways of adjusting knob at the drill chuck, adjustable drill and percussion drill. But the impact drill uses the gears on the inner shaft to jump to achieve the impact effect, but the impact force is far less than that of the electric hammer. It can also drill reinforced concrete, but the effect is not good.
The electric hammer is different. It uses the bottom motor to drive two sets of gear structures. One set realizes the drilling and the other drives the piston. It is like the hydraulic stroke of the engine, which produces a strong impact force. With the drilling effect, the force can be Crack the stone and divide the gold.
The electric pick is to let the motor drive the swinging mound to run in a bounce mode, so that the pick has the effect of gouging the ground.
