The difference between electric drill, electric hammer and percussion drill and USES

 Electric drill, electric hammer, the similarities and differences between the impact drill and drill have only rotating way, particularly suitable for the need to a small force on the materials of drilling, such as cork, metal, brick, tile, etc. Electric hammer and pounding on spin to work. A single pounding force is very high, and have the beat frequency of 1000 to 3000 per minute, can produce significant force.

Compared with percussion drill, electric hammer need minimum pressure to go hard material, such as stone and concrete; Relatively hard concrete especially.

Impact drill and impact on spin to work. The impact of the single is very slight, but the impact of more than 40000 times per minute frequency can produce continuous force. Impact drill can be used for natural stone or concrete. They are universal, because they can use the "single diamond" model, also can use "percussion drill" model, so for professionals and for themselves, it is worth to select the basic electric tools.

Electric drill, electric hammer, impact drill is used to punch, electric hammer are commonly used to drill on concrete is hard objects, bit is alloy steel, while drilling, has the function of the hammer. Electric drill is used to drill on relatively resilient objects, bit is generally steel.

Impact drill with electric hammer and drill function, it can used as a hammer, and as a drill. There are two types of drill bit.

Electric drill and the difference between electric hammer drill and electric hammer has the essential difference between: (1) the size is different. (2) of course component is also not the same. Electric drill, only the motor (rotor and stator) and gear bite each other and some revolutions, electric hammer is different, should be called "hammer" so it have impact, can drill concrete, stone and other hard material. So the volume of a hammer bigger than a drill, there is a cylinder should be electric hammer, connecting rod, piston and other important parts.

And electric drill can drill drilling wood, iron, plastic and other materials.

Electric hammer is the use of the piston movement, compressed gas drill bit, do not need to hand make how much strength, can be in the concrete. The bricks. Stone and other hard material 6-100 - mm hole, hole hammer on the above materials with high efficiency, but it cannot open hole on the metal.

Electric drills impact, need human pressure on metal, wood and other materials in the hole, 6-50 mm diameter. The advantage is little vibration, high precision hole, the price is not high. In addition they use the drill bit is different also, the former is set with alloy bit, which is common cutting bit. Electric hammer and percussion drill can be hole in concrete structures.

Both have the function of the piston movement, electric hammer is suitable for large diameter such as more than 30 mm. The advantage is with high efficiency, large aperture, long drilling depth. The disadvantage is that vibration is big, damage to the surrounding structures have a certain degree. Impact drill is suitable for the 25 mm or so small and short condition such as drilling depth. Such as installing bolts, etc.

Little effect on the destruction of the surrounding structures. Air conditioning installation besides wear wall Kong Yi electric hammer. Other location should use electric drill.

The difference between; Electric hammer drill with clip-on lock assembly, simple, without any tools. Drill bit needs special key to tighten
