This article mainly introduces the working principles of impact drills and electric hammers, applicable objects, comparison of advantages and disadvantages, and suggestions for use in decoration.

Working principle: 

Impact drills mainly rely on rotation and impact to work. Although a single impact is very slight, the impact frequency of up to 40,000 times per minute can produce continuous force; while electric hammers mainly rely on rotation and hammering to work. , the single beating force is very high and has a high beating frequency, with a beating frequency of 1,000 to 3,000 per minute, which can produce significant force.

Applicable objects: 

The impact drill is mainly suitable for drilling in wood, metal, ceramics and plastics. It can also impact drill on concrete floors, walls, bricks and stones. However, the effect is not very ideal, while the electric hammer can drill holes on harder materials. Drilling holes in concrete, stone, and wall tiles is very effective and can produce strong impact. Along with the effect of the rotary drill, the power can split stones and divide gold.

Comparison of advantages and disadvantages: 

Impact drills have a wide range of uses and are easy to use. However, it is difficult to grasp the direction of the impact drill when using it, and it is easy to make operating errors, resulting in larger openings. In addition, the drill bit is not sharp, making the holes not neat, with burrs or burrs appearing. Cracks: The advantages of the electric hammer are high efficiency, large hole diameter, and long drilling depth. The disadvantage is that the vibration is large and it has a certain degree of damage to surrounding structures.

Is it better to use an impact drill or an electric hammer for decoration? 

Impact drills can drill and have a bit of a hammering effect. They are suitable for drilling holes in metal, ceramic tiles, and wood. They can also drill reinforced concrete and are generally used for home assembly of furniture, installation of shelves, lamps, etc. Applicable; the electric hammer can not only drill but also has a high hammering effect. It is suitable for drilling on concrete and stone. It is the first choice for professional installation and engineering construction.
