How to use an electric drill? What are the precautions for using an electric drill correctly?
As a hand-held power tool, electric drill has the advantages of small size, light weight, easy to carry, safe and reliable to use, etc. It is widely used in the drilling of metal or non-metal parts in construction, wood processing, bridge construction, mechanical assembly and other departments Operation. So, how do you use an electric drill? We all know that the correct use of electric drills is very important, so how to use electric drills correctly? Before using the power drill, you need to install the drill bit first. If the drill bit is not installed or installed incorrectly, it is easy to be dangerous in use. So, this step is very important. How to install the drill bit? First, the power drill needs to be disconnected. Then, put on gloves as much as possible, hold the electric drill with one hand, hold the hoist opening of the electric drill with the other hand, and rotate it hard to expose the hole where the drill bit is installed. If the electric drill has a ring of teeth in the front section, it is necessary to use a special key to determine the installation hole position. Next, hold the drill bit to be installed, put it on the hole exposed at the front end of the electric drill, turn the drill bit clockwise, and adjust the depth of the main drill bit into the hole at any time, until it is finally tightened and locked. Finally, connect the power supply, after the power is turned on, idle for 2 seconds to confirm whether the drill is installed firmly. In fact, many electric drill bits are installed in a similar way and can be installed according to the instructions in the manual. Before using it, you also need to fully understand the functions of some other accessories of the electric drill. For example, on the fuselage of the electric drill, you can choose the drilling direction. The arrow of the button is forward, that is, it rotates clockwise, and the arrow of the button is reversed, that is, it rotates counterclockwise. The turning circle of the fuselage head can adjust the torque of the electric drill, and the torque can control the power of the drill bit. The top of the fuselage can adjust the drilling speed. The force of pulling the trigger can be used to adjust the speed at which the drill turns. In front of the base of the electric drill you can place spare drill bits, etc. In addition, among the types of electric drills, there are hand-held electric drills, impact drills, and corded electric drills. Among them, the power of the impact drill is relatively large, and the drill bit is designed with a slot. In use, do not rotate and fix it. Cord drills are relatively powerful and are mostly used for larger projects. After mastering the various functions of the electric drill and installing the drill bit, just power on the electric drill and you can use it. Generally, when using the electric drill, you only need to hold the electric drill, fix the object that needs to be drilled, and pull the trigger of the electric drill. However, in actual operation, there are still some matters that need to be paid attention to, which are related to personal safety and operation efficiency. The first is to do personal protection before use. Wear a face shield and protective glasses, especially when working with your face up. If you are working at heights, you should also pay attention to taking measures to fall from heights. Secondly, when using it, try to hold it tightly with both hands, and try not to operate it with one hand. In addition, the drilling force should be moderate, and the drilling force should not be too strong or too violent, so as to avoid the drill bit flying out and hurting people. During use, if it is found that the spark is too large, the electric drill is overheated, etc., be sure to stop and check to see if there is dirt to be removed, or the brush is worn and needs to be replaced, etc., and do not continue to operate with dangerous factors. After use, remember to maintain and check. If the drill bit is found to be dull or bent, it needs to be replaced with a new one, or if the fastening screws of the electric drill body are found to be loose, they need to be re-tightened in time. In this way, the electric drill can be better used for work. In fact, after understanding how to use the electric drill, you will find that the use of the electric drill is quite simple. However, only by using the correct method of use in the use of the electric drill can the safety of the operation be ensured, and the electric drill can be used by us and play its due role. Therefore, when using an electric drill, be sure to use it correctly and pay attention to safety.
