The family of electric drills is collectively dispatched to see the strength of different types of electric drills.

As the saying goes, "When a worker wants to do something good, he must first sharpen his tools." Choosing the right electric drill when installing a punch can have a multiplier effect. There are many kinds of electric drills that are commonly used on the market, such as hand drills, impact drills, and hammer drills, and their application ranges are quite different. This article will introduce the types of electric drills in detail, to see how the different types of electric drills are different from the purchase points, and provide a reference for everyone to purchase electric drills.

Hand drill

The hand drill is only available in a rotating manner and is particularly suitable for drilling holes in materials that require 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, so that the drill bit can be scraped in the form of scraping on metal, wood and other materials.

Hand drill

Scope of application : Screwing, furniture assembly, mounting racks, curtains, etc.

Note : Can not be used to drill cement and brick walls, otherwise it will easily cause motor overload and burn the motor. The key is that there is no impact mechanism in the motor and the bearing capacity is small.

Optional points : There are many types of hand drills. When equipped with positive and negative switches and electronic speed control devices, they can be used as electric screwdrivers. Some models are equipped with rechargeable batteries, which can be used without any external connection within a certain period of time. The power supply works normally; the right angle electric drill, the electric drill head and the fuselage are 90 degrees, suitable for use in a narrow working space. 【

Impact drill

Impact drills rely on rotation and impact to work on natural stone or concrete. When the impact drill is working, there are adjustment knobs at the drill chuck, which can be adjusted by ordinary hand drill and impact drill. Therefore, it has the function of ordinary hand drill, and can also drill reinforced concrete like electric hammer, but the effect is not good.

Impact drill

Scope of application : wood, metal, tile drilling, concrete below 10 mm

Note : Impact drills cannot be used for electric drills in general, because the impact drills are difficult to grasp when used, and are prone to misoperation and large openings.

Optional points : The larger the drill bit size, the higher the price will be. The average household size is usually 20mm. In addition, the same type of impact drill, the more additional functions, the higher the price, the model The presence of R indicates that the drill bit can be reversed and the model has an E indicating that the drill can be adjusted. 【

Electric hammer

The electric hammer works by rotating and beating, has a very high single-strike force, and has a beating frequency of 1,000 to 3,000 per minute, which produces 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.

Electric hammer

Scope of application : hard concrete, stone drilling, professional installation, engineering construction

Matters needing attention : the vibration of the electric hammer is large, which has a certain degree of damage to the surrounding structures; the steel bars in the concrete structure cannot pass smoothly.

Optional points : Be sure to select the electric hammer with speed switch. When the switch is light, the speed is lower, which can help the machine to start drilling smoothly. High speed can be used to ensure working efficiency during normal operation; It is inevitable that the drill will be stuck if the hammer is drilled. If it is not reversed, it will be very laborious and easy to get hurt. 【

Electric pick

The electric shovel is a double-insulated hand-held electric tool powered by a single-phase series-excited motor. The power of the electric motor makes the hoe have the effect of hitting the ground. Its power is very large, full of power, completely fearless of hard concrete and stone, but the electric hoe does not rotate, can only be cut.

Electric pick

Scope of application : Widely used in construction engineering, crushing, leveling, excavating, slotting and cutting concrete, masonry and asphalt pavement.

Note : The electric cymbal is an intermittent working tool. When the work is overheated, the work should be suspended. It is recommended to cool for 5 to 10 minutes after continuous operation every 10 to 15 minutes.

Optional points : Most of the eMules are equipped with professional construction personnel, which are rarely used by ordinary families. Therefore, it is best to use electric hammers for electric power, so that the scope of use is wider. The anti-slip performance of the eDonkey handle is critical, otherwise it is difficult to control the huge recoil
