1. Working principle
The impact drill mainly relies on rotation and impact to work, although a single impact is very slight, but up to 40,000 times per minute impact frequency can produce continuous force; The electric hammer, which mainly relies on rotation and hammering to work, has a very high single hammering force and a high hammering frequency, with 1,000 to 3,000 hammering frequencies per minute, which can produce significant force.
2. Applicable objects
The percussion drill is mainly suitable for drilling on wood, metal, ceramic and plastic, and can also impact drilling on concrete floors, walls, bricks and stones, but the effect is not ideal; The electric hammer is very effective for hard concrete, stone, wall brick drilling, can produce a strong impact, accompanied by the effect of rotary drilling, the force can be split stone gold.
3. Compare advantages and disadvantages
Hammer drill is widely used and convenient to use, but the direction of hammer drill is not easy to grasp when it is used, and it is easy to operate wrong, resulting in a large opening. In addition, the drill is not sharp, so that the opening of the hole is not neat, burr or crack; The advantages of the electric hammer are high efficiency, large aperture, long drilling depth, and the disadvantage is that the vibration is large and the surrounding structures have a certain degree of damage.
4. Is it better to use a hammer drill or an electric hammer for decoration?
Hammer drill can drill with a little hammering effect, suitable for metal, tile, wood drilling, can also drill reinforced concrete, general family assembly furniture, installation shelves, lamps and other applications; The electric hammer can not only drill and high hammering effect, suitable for concrete, stone drilling, is the first choice for professional installation, engineering construction.
