Impact drills rely on rotation and impact to work, and are mainly suitable for impact drilling on concrete floors, walls, bricks, stones, planks and multi-layer materials. One of the most widely used hardware tools in decoration and other industries, many people may not understand it, so what is the principle of impact drill? How to use the impact drill correctly? Next, Hanguda will explain it to you, let's take a look together.

The principle of impact drill:

The working principle of the electric drill is that the motor rotor of the electromagnetic rotary or electromagnetic reciprocating small-capacity motor performs magnetic field cutting and work operation, and the operating device is driven by the transmission mechanism to drive the gear to increase the power of the drill bit, so that the drill bit scrapes the surface of the object and penetrates the object better. . The impact mechanism of the impact drill has two types: dog tooth type and ball type. The ball impact drill is composed of a moving plate, a fixed plate, and a steel ball. The moving plate is connected with the main shaft through threads and has 12 steel balls; the fixed plate is fixed on the casing with pins and has 4 steel balls. Under the action of thrust, the 12 steel balls roll along the 4 steel balls. The cemented carbide drill bit produces rotary impact motion, which can drill holes on brittle materials such as bricks, blocks, and concrete. Take off the pin so that the fixed plate rotates with the moving plate without impact, which can be used as a common electric drill.

 

How to use the impact drill correctly?

First, before using the impact drill, plug the power supply to see if the power supply matches the rated 220V voltage on the impact drill, and do not connect it to the 380V power supply by mistake.

Second, before the impact drill is plugged in, carefully check the insulation protection of the body. If the broken copper wire is found to be exposed, immediately wrap it with insulating tape to check whether there are loose screws on the hand drill body.

Third, install the standard drill bits that match the allowable range of the impact drill bits, and do not force the use of drill bits that exceed the range.

Fourth, when the impact drill is energized, the wires should be well protected, and they should not be dragged on sharp metal objects to prevent them from being rolled and cut, and do not drag the wires into oil and chemical solvents to avoid corrosion of the wires.

Fifth, the power socket of the impact drill is equipped with a leakage switch device. If the impact drill is found to have leakage, abnormal vibration, high heat or abnormal noise, stop working immediately, and find an electrician to check and repair it in time to troubleshoot.

Sixth, when replacing the drill bit for the impact drill, use a special wrench and drill bit to lock the key, and it is strictly forbidden to use a hammer, screwdriver, etc. to hit the impact drill.

 The principle of impact drill and the introduction of how to use it correctly, I believe you should have more understanding after reading it. The content is for your reference only, and I hope it can be helpful to you.
