What is a power tool? Is there any difference between a Hammer Drill 28MM BHD 2808, an impact drill, and an electric hammer? How to choose a hand tool for home improvement drilling, or when repairing a computer and screwing screws? hammer.

An electric drill is a drilling tool that uses electricity as power. It is a conventional product in power tools, and it is also a power tool product in high demand. Electric drills only have a rotating method and are suitable for drilling holes on materials that require very little force, such as cork, metal, brick, ceramic tile, etc. The electric drill only relies on the rolling force of the motor to drive the gear bit, so that the bit can scrape through the metal, wood and other materials. Impact drills rely on rotation and impact to work on natural stone or concrete. During the operation of the impact drill, there is a knob at the chuck of the drill bit, which can be adjusted by two methods: the general hand drill and the impact drill. However, the impact drill uses the gears on the inner shaft to beat each other to complete the impact, 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. An electric hammer is a type of electric drill that is used to drill holes in concrete, floors, brick walls and stone. Drilling holes on walls, concrete and stone, as well as a multi-functional electric hammer, can replace the use of ordinary electric drills and electric picks with the appropriate drill bit in the right position. The electric hammer uses the bottom motor to drive two sets of gears, one set to complete its drilling, and the other set to drive the piston, just like the hydraulic stroke of the engine, the impact force generated is accompanied by the role of the drill. Strength can split stone and divide gold.
