Why do I need a household electric drill as a young man? First, I saw a lot of people in the online comment area before asking whether the "
Mijia Electric Screwdriver" can be used as an electric drill. In fact, this
Electric Screwdriver has only 5N.m high torque and is equipped with 12 S2 steel bits. Can't reach the function of electric drill. Therefore, household electric drills still have demand scenarios for some people. Second, in the home, it is inevitable to punch holes on the wall, for example, to install a
Vacuum Cleaner bracket or picture frame on the wall. Thirdly, electric drills are also a must-have tool for some craft lovers with strong hands-on ability.
For this reason, I recently started a crowdfunding in Xiaomi Mall. The crowdfunding price is 449 yuan (original price 499 yuan). The Mijia brushless smart home electric drill. How does this young man`s first smart electric drill perform?
After using it for a few days, personally, I think this product is good. To sum it up, there are the following 5 points. First, the use method is also simple and easy, because the Mijia brushless smart home electric drill provides three operation modes ( Manual M gear, smart A gear, pulse gear), press the button at the bottom of the display to switch at any time.
Second, it is not only a household electric drill, but also an electric screwdriver. Someone complained or worried that the Mijia electric screwdriver could not be used as an electric drill. Now this product has solved it perfectly.
Third, the body adopts Type-C charging interface + built-in 2000mAh high-capacity lithium battery. This design has advantages and disadvantages. The advantage lies in the innovative battery layout design, without the need for additional bulky battery packs. The disadvantage is that the battery cannot be removed and replaced. Once the battery is dead, it needs to be fully charged before use.
Fourth, for soft pine, hard beech and other wood, aluminum alloy pipes, steel plates and other metal and plastic water pipes, acrylic and other plastic materials, Mijia brushless smart household electric drills can easily deal with them. They can be drilled and screwed. During use, It is important to note that you cannot drill into the wall.
Fifth, in terms of safety, it not only adopts continuously variable trigger design and release slow stop design, which can protect users in high torque mode, but also adopts brushless motor, which is safe and non-sparking, which further guarantees the safety of use.
In appearance, the Mijia brushless smart home electric drill uses a minimalist screwless design. The product continues the minimalist design style of Mijia screwdrivers, with smooth lines and no visible screws on the surface. Coupled with a grip design that fits the Asian hand shape, the grip is more comfortable and reliable.
In terms of material, the whole machine adopts PC+ABS high-strength engineering plastics, which is sturdy and durable. In addition, the body's metal baking paint + UV topcoat has two surface processes, presenting a high-grade matte metal texture, which is scratch-resistant and stain-resistant.
As a smart product, it is bound to break the traditional tool concept. This product is equipped with a smart high-definition display at the back of the fuselage, which can display the current operating mode and manual gear numbers in real time. It is worth noting that the battery status and the gear position in manual mode can also be displayed on the display.
Therefore, compared with the traditional electric drill without a display screen, the working status of the electric drill cannot be known during operation, which is very easy to cause mistakes. Mijia's brushless smart home electric drill breaks through the traditional tool concept, allowing the working status of the electric drill to be seen at a glance, and the working status is under control.
Compared with the traditional brushless motor, which is small in size and strong in power, the Mijia brushless smart home electric drill uses a powerful brushless motor with a maximum torque of 30N.m and a maximum speed of 1400rpm, thus achieving the goal of safety and no sparks. Of course, the brushless motor also has many characteristics of "small wear, low noise, high power conversion rate, no need to replace carbon brushes, and longer service life".
In addition, the handle has a built-in 2000mAh high-capacity battery. It is reported that 550+ self-tapping screws can be drilled under full power, or continuous 6mm steel plate 22+ times, or 4cm deep holes in the wood board 280+ times.
In terms of charging interface and battery life, the body adopts Type-C charging interface, with the included 22.5W fast charging adapter and 1m charging cable, which is convenient for charging at any time.
1. Two gears, one machine for two purposes
The Mijia brushless smart home electric drill has a built-in all-metal variable-speed gearbox, and you can freely switch the drilling gear/screw gear by turning the shift button on the front of the fuselage.
In the actual experience, I moved the shift button on the front of the fuselage to freely switch the drilling gear/screw gear. The actual operation experience diagram:

Drilling block
In addition, in actual experience, I found that the back half of the grip is covered with matte TPU soft rubber, which is comfortable to the hand and has a certain anti-slip effect. It is reported that TPU soft glue is not easy to turn yellow and sticky. This can only be verified after using it for a long time in the future, but such a design can be regarded as a bonus item for the product.
2. Three usage modes
Three operating modes: smart A gear/manual M gear/safe pulse gear, which can be switched at any time by pressing the button at the bottom of the display. 1) Smart A gear Built-in smart chip, automatically matching the appropriate torque according to the use scene, the screw is automatically locked after being tightened, and the screw is tightened in one step to avoid damage or spattering of the screw due to over-turning.
2) Manual M gear For the advanced needs of professional users, it is recommended to use manual M gear. First, the 360° stepless knob, up to 30 gears, can be adjusted step by step, and can also be quickly turned to skip gears. Second, the maximum torque or speed can be controlled separately according to the different modes of drilling/screw screwing, accurately and meticulously.
3) Safe pulse block For novices, it is recommended to use safe pulse block. First, the intelligent chip controls the speed, and the electric drill starts and stops intermittently to further ensure the safety of use. Second, it can also effectively reduce the damage to the material when it is used on soft materials.
3. Infinitely variable speed, release and slow stop Dynamic demonstration:
The infinitely variable trigger design of the Mijia brushless smart household electric drill, the speed gradually increases with the pressing force. It is worthy of praise that such a release and slow-stop design can protect the user in high torque mode.
4. Installation and use
In terms of installation, you need to pay attention to the "extension rod" only when you switch to the screw stop, as shown in the following figure:
And when installing the drill bit, first move the shift knob on the front of the fuselage, switch to the screw stop, and then rotate the position of the drill bit on the front of the fuselage to clamp and fix the extension rod.
Similarly, installing the drill bit is the same operation, but there is a slight difference. The front of the fuselage also needs to be rotated several times. The three embedded metal brackets are screwed out, and the small drill bit is clamped and fixed firmly to the rear before use. . By comparing the following two pictures, we can see the difference before and after the drill bit is installed.
Before installation
After installation
When switching to the drill block, you also need to pay attention to the use scenarios and differences of the 7 drill bits. Among them, 3 black twist drills are only suitable for metal drilling, and the other 4 woodworking drills are suitable for wood or plastic.
Dynamic demonstration of metal drilling and perforation:
Dynamic demonstration of drilling wood:
On the outer packaging, the product adopts a minimalist packaging design, the front is the physical rendering of the product, the lower left corner is the product selling point, the lower right corner is the batch number, and the back is the product parameter information.
In terms of accessories, the accessories are also very abundant, including electric drill host, manual, a Type-C charging cable, integrated storage carrying case, and 24 S2 steel bits of different models.
Among them, the integrated storage portable bag is made of water-repellent fabric. The main unit, accessory box, adapter and charger can all be stored in the bag, which is simple and neat.
In addition, there are 24 S2 steel bits of different models, including 9 common categories, with a hardness of up to 60HRC, which is tough and durable.
In addition to looking good and many, a wealth of bit accessories can also meet your drilling requirements of various materials, such as a 60mm magnetic extension rod, which fully covers a variety of operating scenarios; 8 woodworking drills and metal twist drills of different specifications, calmly deal with Drilling needs of various materials.
Dynamic demonstration of batch removal and storage:
Of course, the product also has shortcomings. First, the built-in battery is not removable and does not support replacement. Second, it does not support Mijia APP access. For example, it can perform battery query and real-time data synchronization, and Mijia APP directly controls gear switching. One-key setting of manual velocity value, etc.
In summary, the Mijia brushless smart home electric drill has an exquisite appearance design and a small and exquisite shape. It is not only an electric drill but also an electric screwdriver. The key is to break through the concept of traditional tools and integrate into the smart display design, real-time display the direction of rotation of the electric drill in the current operating mode, turning out and turning into the control room, improving the overall portability and operating pleasure. In addition to 24 S2 steel bits of different models and support for Type-C charging, the carrying case is integrated in one storage. Whether you are from a tool novice to a professional player, or from daily use to renovation, it can reach different groups of people with one click Use requirements in multiple scenarios.
