As is well known, electric hand drills are drilling tools powered by AC power or DC batteries, and are a type of handheld electric tool. It is mainly used in industries such as construction, decoration, furniture, etc., to make holes or pierce through objects. In some industries, it is also known as an electric hammer. There are quite a few drilling tools on the market now. How can I choose a good pistol style electric drill?

Nowadays, there are mainly two types of drilling tools: impact drills and electric hand drills. Impact drills are generally used to drill concrete or holes in walls, with relatively high power, while electric hand drills are generally low-power, such as drilling iron sheets or wood. And for our general civilian use, hand electric drills are about the same. Because electric drills are used to drill metal, wood, and plastic. Not suitable for drilling buildings, inefficient. The structure of a motor is reduced by gears to increase torque.

Electric drills are one of the most commonly used handheld electric tools. General hardware stores, ranging from professional hypermarkets to small roadside hardware stores, sell electric drills. In order to purchase satisfactory electric drills, the following points should be noted.

1、 Electric drill products are mandatory certification products stipulated by the National Certification and Accreditation Administration. Therefore, when purchasing, the first step is to check whether the tool has the 3C mark. The general method of checking is to check whether there is the 3C mark on the outer packaging or nameplate of the tool. If there are still doubts about this (due to the manufacturer of electric drills not passing the annual supervision and review, the National Certification and Accreditation Administration may suspend or revoke their certificate), they can go to the website of the National Certification and Accreditation Administration, Check if the 3C certificate for this tool is currently valid.

2、 When purchasing electric drills, it is recommended to choose reputable and influential large companies, as these companies have strong technical capabilities, strict quality control, and standardized after-sales service. Users with strong purchasing power can also choose to purchase tools from international brands.

3、 According to the needs of users, it is necessary to distinguish between home use and professional use. Since most electric drills are designed for professionals, it is important to distinguish between professional and general home use tools before purchasing. The difference between professional and general household tools is usually in terms of power. Professional tools have a higher power to facilitate professionals in reducing workload. General household tools, due to their small engineering size and relatively small workload, do not require a large input power.

4、 Observe the outer packaging of the electric drill. The outer packaging of the tool should have clear patterns and no damage. The plastic box should be sturdy, and the buckle for opening the plastic box should be firm and durable.

5、 Observe the appearance of the electric drill. The appearance of the tool should be uniform in color, with no obvious shadows or dents on the surface of the plastic parts, no scratches or collision marks. The assembly misalignment between the shell parts should be ≤ 0.5mm. The aluminum casting coating should be smooth and beautiful without defects, and the surface of the entire machine should be free of oil stains and stains. When holding with your hand, feel good and the handle of the switch should be flat. The length of the cable should generally not be less than 2 meters.

6、 Check the nameplate and instruction manual of the electric drill, and the nameplate parameters of the tool should be consistent with those on the 3C certificate. The manual should include detailed addresses and contact information of the manufacturer and manufacturer. There should be a traceable batch number for the product on the nameplate or certificate of conformity.

7、 Hold the electric drill with your hand, connect the power, frequently operate the switch with your hand to start the tool frequently, and observe whether the on-off function of the tool switch is reliable. Simultaneously observe whether there are any abnormalities in the television and fluorescent lights on site. To confirm if the tool is equipped with an effective radio interference suppressor.

8、 The electric drill should be powered on for one minute and held by hand during operation. There should be no obvious abnormal vibration in the hand. Observe the commutation spark, and the commutation spark should not exceed level. Generally, when viewed from the air inlet of the tool, there should be no obvious arc light on the surface of the commutator. During operation, there should be no abnormal noise

Correct Use and Selection Method of Lithium Electric Drill

The main components of a hand electric drill include a drill chuck, output shaft, gear, rotor, stator, casing, switch, and cable. There are not many parts, but most lithium drills have poor cost-effectiveness. The Baichen pistol type electric drill has a continuously variable speed, self adjustable reverse rotation, and intelligent automatic braking function. This electric drill has a powerful motor with high functionality and a lithium battery with long standby time, making it very stable and convenient for us to operate. I like the big advantage of it is that it can drill with infinitely variable speed at a speed that is super fast and super awesome. With its humanized pistol handle, women can also operate it freely, which can reduce the user's workload and avoid fatigue. There is a self-locking switch in the handle position that can be locked at any time. It is both convenient and safe to operate, and very simple. Due to its small size, durable all bearings, and stepless speed regulation for forward and reverse rotation, this electric drill is fully capable of replacing screwdrivers and keyless self-locking chucks, allowing for quick replacement of drill bits. It is lightweight and convenient. It is a good choice to use in daily life.
