Percussion drilling hole is too large
1. Generally, electric drills are of low power. They drill iron sheets and wood. Percussion drills are usually made of concrete, or holes in the wall, which has a high power.
2. Ordinary electric drill has only rotating force, while impact electric drill has an axial vibration force besides rotating force.
3. Ordinary electric drills can drill holes in various metals, wood, plastics and other materials.
Because of the hard and brittle characteristics of stones, bricks and concrete and the strong wear and tear of metal drills, it is necessary to use impact electric drills to drill holes in these materials. The impact and rotation of impact electric drills are used to drive and rotate while beating and turning, and the stones are cut and ground bit by bit into a hole.
If ordinary electric drill is used to drill holes in stone or concrete, the edge of ordinary drill is quickly worn out. The purpose of impact and rotation is to improve the efficiency of drilling.
4. Ordinary electric drills can only be used to drill metal, wood, or screw and other operations, not to drill concrete. In addition to drilling metal and wood, percussive drilling can drill bricks, walls and ordinary concrete.
For families, percussion drill is more suitable for home users. Although electric hammer can hit the wall and can also be fitted with connecting rod chuck, the accuracy of electric hammer clamp is not as good as percussion drill, because electric hammer is most suitable for wall drilling, and percussion drill appears to have a wide range of functions, which is the best choice for home users.
