The working principle of an electric drill is that the rotor of an electromagnetic rotary or electromagnetic reciprocating small-capacity motor performs magnetic field cutting and power operation, and drives the working device through the transmission mechanism, driving the gear to increase the power of the drill bit, so that the drill bit scrapes the surface of the object and penetrates the object better.
An electric drill is a drilling tool that uses electricity as power. It is a conventional product among power tools and is also a product of extremely high demand for power tools. The electric drill only has a rotation method, which is particularly suitable for drilling holes in materials that require very little force, such as cork, metal, brick, and tile. The electric drill simply relies on the motor to drive the transmission gear to increase the force of the drill bit rotation, so that the drill bit can scrape and penetrate metal, wood and other materials. The impact drill relies on rotation and impact to work, and can be used for natural stone or concrete. When the impact drill is working, there is an adjustment knob at the drill chuck, which can adjust the two methods of ordinary hand drills and impact drills. However, the impact drill uses the gears on the inner shaft to jump against each other to complete the impact effect, and the impact force is far less than that of the electric hammer. It can also drill reinforced concrete, but the effect is not good. Electric hammer is a type of electric drill, mainly used to drill holes in concrete, floor, brick wall and stone. It is specialized in drilling holes on walls, concrete and stone. There are also multi-function electric hammers, which can replace ordinary electric drills and electric picks when adjusted to the right position and equipped with the right drill bit. The electric hammer uses the bottom motor to drive two sets of gear structures, one set to complete the drilling, and the other set to drive the piston, just like the hydraulic stroke of the engine, generating a strong impact force, accompanied by the effect of drilling. The force can split stones and separate gold.
