Nowadays, families use many electric tools, but there are also many types of electric hammer drills. If you don’t know, it will have an impact. I teach you the main points of buying a (21v li ion cordless brushless hammer drill).
First of all, what is a hammer drill?
An electric hammer is a type of electric drill, which is mainly used to drill holes in concrete, floors, brick walls, and stones. Drill holes in walls, concrete, and stones, and use a multifunctional electric hammer. Adjust to a suitable position and install a suitable drill bit, which can replace ordinary electric drills and electric picks. The advanced hammerhead switch makes the hammer bit and bit in different working conditions. In other words, only applying rotation will not produce impact, only applying impact will not rotate, and impact and rotation can be applied at the same time.
Secondly, what are the advantages and disadvantages of a ( power drill)?
Advantages: high efficiency, large aperture, long injection depth.
Disadvantages: The vibration is large, and it has a certain destructive effect on the surrounding structure. The steel bars in the concrete structure cannot pass smoothly. According to the requirements of the scope of work, not too close to the building.
Finally, how to buy a hammer drill
1. Positive and negative functions are indispensable. When installing the hammer on the wall, the drill bit will inevitably be stuck, but at this time, just put it back and gently pull it out, and the drill bit will come out. If there is no flip function, it will be very difficult and easy to get injured.
2. Choose a multifunctional electric hammer, that is, an electric hammer with both percussive drill function and drill bit function. After adjusting to the flat drill file, it can also be used as an electric drill. When installing the cabinet, metal holes or wood holes can be used, and the screws can also be removed. The electric hammers currently on the market are basically multifunctional.
3. Lithium battery is more convenient. After lithium is charged, storage becomes simple. However, there are still few lithium hammers on the market.
4. Hammer with governor switch. As the speed is low when the switch is tapped, it helps the machine to drill smoothly. During normal work, high speed can be used to ensure work efficiency.
5. Use a light hammer to make the work easier. It is recommended to use a light hammer. Do not weigh more than 3 kg, and do not use force when working upwards.
