Electric drill classification:
1. Hand drill
The hand drill is only available in the rotation method and is particularly suitable for drilling holes in materials that require very little force, such as cork, metal, brick, tile, etc. The electric drill only relies on the motor to drive the transmission gear to increase the force of the drill bit rotation, so that the drill bit is scraped in metal, wood and other substances.
2. Impact drill
Impact drills rely on rotation and impact to work and can be used in natural stone or concrete. When the impact drill works, there is an adjustment knob at the drill bit chuck, which can be adjusted in two ways: ordinary hand drill and impact drill, so it has the function of ordinary hand drill, and can also drill reinforced concrete like an electric hammer, but the effect is not good.
3. Electric hammer
Electric hammers work by spinning and pounding, with a single pounding force being very high and with a thumping frequency of 1,000 to 3,000 per minute, generating significant force. Compared to impact drills, electric hammers require minimal pressure to drill into hard materials such as stone and concrete, especially relatively hard concrete.
4. Electric pickaxe
The electric pickaxe is a double-insulated handheld power tool powered by a single-phase series motor, which uses the power of the motor to make the pickaxe head have the effect of gouging the ground. It is very powerful, full of power, completely unafraid of hard concrete and stone, but the head of the electric pickaxe does not turn, can only be chiseled.
The difference between electric drill, impact drill, electric hammer
1. Electric drill
It is a drilling tool powered by electricity. It is a regular product in power tools, and it is also the most demanded power tool product. Electric drills are only available in rotation and are particularly suitable for drilling on materials that require very little force, such as cork, metal, brick, tile, etc. The electric drill only relies on the motor to drive the transmission gear to increase the force of the drill bit rotation, so that the drill bit is scraped in metal, wood and other substances.
2. Impact drill
Relies on rotation and impact to work and can be used in natural stone or concrete. When the impact drill works, there are adjustment knobs at the drill bit chuck, which can be adjusted in two ways: ordinary hand drill and impact drill. However, the impact drill uses the gears on the inner shaft to jump out of each other to achieve the impact effect, and the impact force is far less than that of the electric hammer. It can also drill reinforced concrete, but it is not effective.
3. Electric hammer
It is a type of electric drill, mainly used to drill holes in concrete, floor slabs, brick walls and stone. Professional drilling on the wall, concrete, stone, as well as a multi-functional electric hammer, adjusted to the appropriate position with the appropriate drill bit can replace the ordinary electric drill, electric pick. The electric hammer uses the bottom motor to drive two sets of gear structures, one to drill, and the other to drive the piston, just like the hydraulic stroke of the engine, producing a strong impact force, accompanied by the effect of drilling. Power can split stones and divide gold.
