How to choose an electric drill? Look here if you are inexperienced

Electric drills are commonly used power tools in home decoration and maintenance. They are mainly used for drilling, tapping and screwing. When purchasing an electric drill, you need to consider it based on your actual needs and budget. The following will introduce the key points for purchasing an electric drill to help you choose the one that suits you.

1. Types of electric drills

1. Hand drill

A hand drill is a lightweight power tool that is easy to use and can be carried anywhere. It is mainly used for drilling holes in materials such as metal, wood and plastic. Hand drills have lower power and speed and are generally used for home repairs and DIY projects.

2. Impact drill

An impact drill is a power tool that has both impact and rotation capabilities. It can drill holes in hard materials such as concrete and brick walls at a fast drilling speed. Impact drills have high power and rotational speed and are suitable for home decoration, construction sites and other occasions.

3. Hammer drill (electric hammer)

A hammer drill is a power tool that combines impact and rotary functions. It has strong electric power and can easily drill through hard materials such as concrete, brick walls, etc. Hammer drills are suitable for use in many areas such as home, renovation, and construction sites, such as home wiring, construction sites, etc.

2. Material of electric drill

do you know? Electric drills are made of a variety of materials, including metal, polymer materials, and tungsten steel alloy. I don’t know if you made the right choice? Let me explain it to you!

1. Metal material

Metal electric drills usually use high-speed steel or carbide steel as the drill bit, and the drill bit and the handle are connected by friction welding. Electric drills made of this material have better cutting performance when drilling and can drill holes quickly. However, metal electric drills are relatively heavy and may make your arms sore when used for a long time.

2.Polymer materials

The drill bit made of polymer material is made of high-strength engineering plastics and has the characteristics of light weight, cheap price and easy use. This kind of electric drill is suitable for small-diameter drilling, but its cutting performance is relatively poor and it is easy to get stuck or burn out the drill bit.

3.Tungsten steel alloy

Tungsten steel alloy is a material with high hardness and high wear resistance, which is often used to make high-speed cutting tools. Electric drills made of this material have high drilling accuracy and cutting performance, can drill holes quickly and are not easy to get stuck. However, tungsten steel alloy electric drills are relatively expensive and not suitable for all users.

3. Use of electric drill

1. Drilling

Electric drills can be used to drill holes and have a wide range of uses. Among them, high-speed drill bits are suitable for drilling wood, plastic, aluminum, etc., while low-speed drill bits are suitable for drilling steel, iron, brass and other metal materials.

2. Polish

Electric drills can also be used for grinding work. Using different grinding heads or grinding wheels, they can grind various materials such as stone, ceramics, glass and metal.

3.Punch holes

Electric drills can be used to drill holes, and the drill bits can be made into different diameters and shapes to meet different needs, such as drilling holes, screw holes, hardware accessory holes, etc.

In summary, a power drill is a versatile power tool that can be used for a variety of tasks such as drilling, sanding, and drilling. Users need to choose the appropriate electric drill type and accessories according to specific work needs to improve work efficiency and quality.

4. How to choose an electric drill

1. Consider power

The power of an electric drill is an important factor affecting its performance. The higher the power of the electric drill, the greater the torque and speed it can produce, and it is suitable for drilling and tapping operations that require greater force. Generally speaking, the power of household electric drills is more common between 700W and 1000W.

2. Consider the speed

The rotational speed of an electric drill is also an important factor affecting its performance. The higher the rotational speed, the faster the electric drill can produce and is suitable for cutting harder materials such as metal. Generally speaking, the rotation speed of household electric drills is more common between 0-1300 rpm.

3. Consider the motor

An all-copper motor means that the winding wire of the motor is pure copper, while an aluminum wire motor means that the winding wire is aluminum. In general, all-copper motors have higher power density, smaller rotational inertia, and relatively larger starting torque, so the performance of all-copper motors is better than that of aluminum wire motors. In addition, the resistivity of the all-copper motor is small, which can effectively reduce power consumption and temperature rise, and improve the service life and stability of the motor. Therefore, when choosing an electric drill motor, it is recommended to choose an all-copper motor.

Key knowledge about electric drills

1. What should I do if the electric drill suddenly stops spinning?

① Check whether the battery is out of power, and replace it if it is out of power.

② Check whether the switch is in poor contact or accidentally touched. If there is any problem, replace the switch.

③ Motor failure requires inspection by professional maintenance personnel.

④ Check whether the drill bit is too tight or too loose and adjust it.

⑤ Check whether the wrong mode is selected and adjust to the correct mode.

2. What should I do if the electric drill wire suddenly emits smoke?

① Turn off the power immediately, pull out the power plug of the electric drill, and cut off the power supply.

② Check whether the insulation layer of the wire is damaged. If there is any damage or burnt phenomenon, replace the wire immediately.

③If the wire is intact, it may be caused by overheating of the electric drill. Place the drill in a well-ventilated place to cool down naturally before using it again.

A power drill is a very useful power tool that can be used for a variety of tasks, including drilling, sanding, and punching holes. By understanding the uses, materials and characteristics of electric drills, users can better select and use electric drills and improve work efficiency and quality. I hope this article can help readers better understand the electric drill as a power tool and play a greater role in practical applications.
