What is the principle of impact drill? How to use the impact drill correctly?

Percussion drilling relies on rotation and impact to work, and is mainly suitable for Impact Drilling on concrete floors, walls, bricks, stone, wood and multilayer materials. One of the more commonly used hardware tools in the decoration industry, perhaps many people do not know much about it, so what is the principle of the impact drill? How to use the impact drill correctly?

Impact drill principle:
The working principle of the Electric Drill is that the motor rotor of the electromagnetic rotary or electromagnetic reciprocating small-capacity motor does magnetic field cutting work, drives the operating device through the transmission mechanism, drives the gear to increase the power of the drill, so that the drill scrapes the surface of the object and penetrates the object better. The impact mechanism of theelectric drill has two kinds: canine and ball. The ball type impact drill is composed of a moving disc, a fixing disc and a steel ball. The driving disc is connected with the main shaft by thread and has 12 steel balls; The fixed plate is fixed on the housing by the use of pins, and has 4 steel balls. Under the action of thrust, 12 steel balls roll along the 4 steel balls, making the carbide drill bit produce rotating impact movement, which can drill holes on brittle materials such as bricks, blocks and concrete. Take off the pin, so that the fixed disc rotates with the moving disc, without impact, can be used for ordinary electric drill.

How to use the impact drill correctly?
First, before the use of the Hammer Drill, it is necessary to see whether the rated 220V voltage phase on the power supply and thehammer drill is compatible, and do not mistakenly connect to the 380V power supply.
Second, before the hammer drill is plugged in, carefully check the insulation protection of the body. If the broken copper wire is found to be exposed, wrap it with insulation tape immediately and check whether the screws on the body of the drill are loose.
Third, in accordance with the allowable range of percussion drill bits to install the matching standard drill bits, do not force the use of drill bits beyond the range.
Fourth, when the hammer drill is used with electricity, the wire should be protected, and it should not be dragged on sharp metal objects, prevent rolling and cutting, and do not drag the wire into the oil and chemical solvents to avoid corrosion of the wire.
Fifth, the power socket of the hammer drill is equipped with leakage switching device. If the hammer drill is found to have leakage, abnormal vibration, high heat or abnormal sound during use, stop working immediately and find an electrician to check and repair in time to eliminate the fault.
Sixth, when replacing the drill bit for the hammer drill, use a special wrench and the drill to lock the key, and do not use a hammer, screwdriver, etc. to knock the hammer drill.

The above is the introduction of the principle of impact drill and how to correctly use impact drill, I believe you should have more understanding after reading it, and hope to help you.
