Electric drill: is the use of electricity as a power drilling machine. It is not only a conventional product of electric tools, but also the largest demand of electric tools. The electric drill only has rotation mode, which is especially suitable for drilling on materials requiring small force, such as cork, metal, brick, ceramic tile, etc. The electric drill only relies on the driving gear driven by the motor to increase the force of the bit rotation, so that the bit can scrape through the metal, wood and other materials.
Percussion drill: it works by rotation and impact. It can be used in natural stone or concrete. When the percussion drill works, there is an adjusting knob at the bit chuck, which can be adjusted in two ways: the ordinary electric hand drill and the percussion drill. But the percussion drill uses the gears on the inner shaft to beat 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 the effect is not good.
Electric hammer: is a kind of electric drill, mainly used in concrete, floor, brick wall and stone drilling. Professional in the wall, concrete, stone drilling, there are multi-functional hammer, adjust to the appropriate position with the appropriate drill, can replace the ordinary electric drill, a electric pick use. The electric hammer uses the bottom motor to drive two sets of gear structure, one to realize the drilling, and the other to drive the piston, just like the hydraulic stroke of the engine, which produces a strong impact force, accompanied by the drilling effect. Strength can split the stone and divide the gold.
What is the difference between electric drill, percussion drill and electric hammer?
It only has rotation mode, especially suitable for drilling on materials requiring small force, such as cork, metal, brick, ceramic tile, etc. Only relying on the driving gear driven by the motor to increase the rotation force of the drill bit, the drill bit can scrape through the metal, wood and other materials.
It works by rotation and impact. Percussion drills can be used in natural stone or concrete. They are universal, because they can use either "single drill" mode or "percussion drill" mode, so they are basic electric tools worth choosing for professionals and hands-on workers.
Relying on rotation and hammering to work, a single hammering force is very high, and has a hammering frequency of 1000 to 3000 per minute, which can produce significant force. Compared with percussion drills, electric hammers require minimal pressure to drill into hard materials, such as stone and concrete, especially relatively hard concrete.
It is to let the motor drive the swing mound to run in the form of bounce, so that the pick has the effect of chiseling the ground. The hydraulic pump pick uses the air pressure transmitted by the air compressor to drive the pump hammer in the electric pick to bounce back and forth, so as to produce the effect of chiseling the ground. But the electric pick only chisels, and its pick does not rotate.
Electric drill can only drill, percussion drill can drill, but also have a little hammering effect. Hammer drill can drill and high hammer, electric pick can only do hammer but not drill.
Selection of drill, percussion drill and electric hammer
Drilling in wood and metal -- percussion drill
If in addition to concrete drilling, but also in wood and metal drilling, and drilling in concrete below 10 mm, you can consider the impact drill, impact drill by helical gear impact, impact force is not as good as electric hammer. But the price is low, such as 500 Watt percussion drill is a good choice.
Tighten or loosen screws -- electric driver
If you often tighten or loosen screws (as computer enthusiasts often do), or punch holes in wood or iron, you can buy a rechargeable electric driver, which is the most convenient tool in these two aspects. Rechargeable electric driver plus a set of driver head set, easy to do the work at hand.
Drilling on wood or iron plate -- electric hand drill
As we all know, electric hand drill is suitable for drilling holes in wood or iron plate, but don't expect it to do much in drilling holes in concrete wall. It's easy to damage the machine. An electric hand drill is the most economical electric tool. Even if it's imported.
Drilling holes in concrete wall -- electric hammer
Due to the cylinder structure of the electric hammer, the hammering force is very high, and has a hammering frequency of 1000 to 3000 per minute, which can produce significant force, making it easy for you to drill holes in the concrete wall. Equipped with a connecting rod and the chuck of an ordinary electric drill, it can also complete the function of an electric hand drill, so as to achieve the purpose of multi-purpose of one machine. Speed control hammer + transfer rod + 13mm electric drill chuck, plus a few commonly used drills, then most of your home decoration tasks can be completed by yourself. Suitable for home decoration, most suitable for drilling holes with a diameter of 10 mm or less.
