What Are The Advantages Of Electric Hammer Drills

Electric tools, electric hammers are a type of electric drill, mainly used to drill holes in concrete, floor slabs, brick walls and stone. Professional drilling on walls, concrete, and stone, as well as a multi-functional electric hammer, adjusted to the appropriate position and equipped with a suitable drill bit can replace ordinary electric drills and electric picks. The high-end electric hammer can use the switch to make the drill bit of the electric hammer in different working states, that is, it only rotates without impact, only impacts without rotation, and both impacts and rotates.

Advantages and disadvantages of electric hammer

Advantages: high efficiency, large hole diameter, long drilling depth.

Insufficiency: The vibration is large, and it has a certain degree of damage to the surrounding structures. The steel bars in the concrete structure cannot pass smoothly. Due to the requirements of the working range, they cannot be too close to the building

HAMMER DRILL
How to choose electric hammer drill

Choose a multifunctional electric hammer, that is, an electric hammer with two functions: hammer drill and flat drill. In this way, it can also be used as an electric drill when adjusted to the level drill gear. It can be used to make holes in metal or wood, and it can also be used to unscrew and unscrew screws when installing the cabinet. The electric hammers currently on the market are basically multifunctional.
Electric hammer with speed switch. When the switch is touched, the speed is low, which can help the machine to start drilling smoothly (for example, drilling on a smooth surface such as a tile, which can not only prevent the drill bit from slipping, but also prevent the hole from breaking). The high speed can be used to ensure the work during normal work. efficient.
The function of forward and reverse rotation is indispensable. When the electric hammer is drilled into the wall, it is inevitable that the drill bit will be stuck. At this time, you only need to adjust the reverse direction and gently pull it out, and the drill bit will come out. If there is no reversal function, it will be very laborious and easy to get injured.
Choose an electric hammer with a shock absorption system. A good shock absorption system can make the operator comfortable to hold and relieve fatigue. Soft rubber handles can also increase grip comfort.
A lighter weight electric hammer can make your work easier. It is recommended to use a light electric hammer, the weight is best controlled below 3KG, it will not be too difficult when working upwards.
Lithium electric hammer is more convenient. Lithium batteries can be charged and used, and storage is more concise. It’s just that there are not many lithium electric hammers currently on the market.
Pay attention to the electric hammer chuck device. If the chuck is square and four pits, you need to buy a square four pit drill. If the chuck is two pits and two grooves, you need to buy a two pit and two groove drill. If you buy randomly without paying attention to the model of the drill bit, it will be troublesome to buy the drill bit that does not fit.
Precautions for the use of electric hammer and electric drill

Check before operation: a. The shell and handle are not cracked or damaged; b. The cable cord and plug are intact, the switch action is normal, and the protective zero connection is correct, firm and reliable; c. All protective covers are complete and firm, The electrical protection device is reliable.
After the machine is started, it should run without load, and the machine should be checked and confirmed that the linkage of the machine is flexible and unimpeded. During operation, the afterburner should be steady and not too strong.
The handle of the electric drill or electric hammer should be mastered during the operation, and the drill bit should be placed on the working surface of the special-shaped rivet when drilling, and then actuate with moderate force to avoid shaking; if the speed drops sharply, reduce the force to prevent the motor from overloading, and it is strictly forbidden to use wood Pressurize.
When drilling holes, pay attention to avoiding the steel bars in the concrete.
The electric drill and electric hammer are 40% intermittent work system, and can’t be used continuously for a long time.
When the working aperture is more than 25mm, there should be a stable working platform, and guardrails should be arranged around it.
Overload use is strictly prohibited. Attention should be paid to the sound and temperature rise during operation. If abnormalities are found, the machine should be shut down for inspection immediately. When the working time is too long and the temperature rise of the machine exceeds 60°C, the machine should be shut down and allowed to cool down before starting work.
During the operation, do not touch the cutting tools, molds and grinding wheels of the electric hammer or electric saw with your hands. If it is found to be blunt or damaged, it should be shut down immediately for repair or replacement, and then continue the operation.
Don’t let go when the machine is rotating.
