After knowing what is worth buying a website a few months ago, I discovered a lot of interests and breaking news. Thanks to the friends for recommending, chopped some cost -effective tools, and I also hope to have some rewards and sharing. As a tool control, the tool series of Fractal1 is naturally happy. Although his own modesty tools are not top -level, the Bosch and Dewei series he configured is high -end in China. As a consumer who cares about cost -effectiveness, the author hopes that the same budget can purchase more categories to enrich DIY capabilities and choices. Therefore The scope of choice of friends.
As a tool -loving tool control, the operating scope includes home improvement/furniture repair, power model, and cooperate with children with small technology production (51 single -chip machine or ARDUino -controlled machine, electrical toys), etc., involving wood, plastic, aluminum, occasional concrete and other materials. The requirements of the tools are different from the decoration company, and they pay more attention to the light, controlled, quality, accuracy, and durability of the tools, rather than a large power and torque. Of course, it is also used by selling iron prices that exceeds the demand, occupying space, which causes family dissatisfaction. For family harmony, it will not be exposed to the uniform works. (Multi -map early warning)
In terms of the selection of the regular electric screwdriver, the function is based on the function of the manufacturer’s propaganda. Because everyone rarely works on the assembly line, it has high requirements for mobility, and rope drills that can screw screws are not considered. In this way, the comparison samples include the Scream function of 5601, 5241, 5262,5228, 1702, and 1702, and take a group photo. The reference information is mainly based on Bosch’s foreign websites, so I thank you! I really hope that domestic manufacturers will also introduce more about how to use them. In the text, try to replace Chinese with the English name of the tool, which is relatively short, otherwise the “rotation impact electric screw batch” similar text will occupy the unnecessary time of everyone.
Principles and measurement
In terms of choosing the right ScrewDriver according to needs, you can refer to the figure below:
The screws often tighten the two workpieces together. The metal class is small in elastic deformation. The wood is that the elasticity is larger. The two workpieces are close to the screw head. The same screwDriver, hard torque is greater than soft torque. The Self-Drilling Screws in the figure should not refer to ordinary self-attack screws, but the screw with a drilling blade on the head. The advantage is that there is no pre-drilling hole. According to different operating conditions, the choice of ScrewDriver is mainly the speed and whether it is impacted by rotation.
5601 belongs to the Housing Grip ScrewDriver. The 3.6V single -section Sanyo dynamic lithium battery is powered. The planetary gear is only 180rpm after the deceleration.
The advantage is that the torque is relatively large, the volume is small, the weight is light, and the rubber package grip is very comfortable.
There are positive and reverse indicators, which are clearly visually suitable for novice use. The lighting switch is controlled independently and can be temporarily a small flashlight. The disadvantage is that there is no torque cup, the torque setting cannot be reduced, and there is no speed regulator (so slow and adjusting). When it is about to be tightened, the electricity can be given to the power. The batch head interface is elastic socket. It is not as convenient as 5228 fast connection, and the same heart is lower. However, its speed is very low, the batch is short, and there is almost no effect. There is no fast charger, which requires enough charging time before use.
The 5601 data I used to introduce torque 5nm, it is estimated that it is a hard twist. Although there is no torque cup, there is a clutch. After reaching the limited torque, it will slip, so that the motor will not be blocked. This time, the newly purchased one, the test machine was clamped by the hexagonal head with a pliers, and even worn the pliers and did not slip. It was suspected that it was to reduce the cost, removed the mechanical clutch, and used the electronic flow limit to protect the motor. The torque is not marked. ~ Just guessing, the limit situation has little impact on most users. This tool can meet the needs of most household disassembling plate furniture and pine wooden furniture screws, which are cost -effective. Although there is no torque adjustment, just twist a dozen screws to adapt. The concentricity is low, the speed is slow, and it is not suitable for drilling. At present, the price of Yi Xun’s mobile terminal is 89 yuan, with a minus of 30 at over 100.
5241 is a single -speed 12V lithium drill with a speed of 500rpm and a maximum torque of 18Nm.
As a ScrewDriver, 5241 is a pretty good choice. As a drill, 10mm jacking is basically enough, but the speed is still slower. It is best to use it as a ScrewDriver, and cooperate with another high -speed electric drill, first guide the guide hole, and then screw the screw, which is very efficient. If there is only one multifunctional diamond, it is troublesome to change back and forth between the drills. This 5241 is the best design and workmanship in the author’s tools. The pointed diamond clamp does not stop the sight when using the short -batch head, and the exhaust port at the tail is protected to prevent foreign objects from entering the carbon brush replacement. The weight is 1 kg, holding the gel, “suitable for Asian hand”. The shell plastic feels delicate and red. It is said to be BASF raw materials.
This tool is suitable for use of high torque requirements for disassembling screws. For example, screwing screws on metal materials, wirling on the wall nails on light steel keels, mechanical screws below M6, and long hexagonal wood screws, in a long hexagonal wood screw, in the screw of hexagonal screws, in the hexagonal screws, in it Screw screws on the hard wood furniture (the expensive wood is used without the screws). A scope of the application scope will be posted later. The author was purchased in JD.com in 2014. At present, Jingdong’s price is not very attractive. If it is not just needed, just wait for the store to celebrate the special offer.
5262 belongs to the 12V dual -speed lithium drill, which is suitable for ScrewDriving and Drilling. The speed is 400rpm and 1300rpm, and the maximum torque is 28Nm. It is very fierce for this 1 kg diamond. The sculpture range is larger than 5241. In addition to the handle, the tail and the deceleration group also have a glue at the tail and the deceleration group, which has a certain anti -fall ability.
However, the detail design is not as good as 5241. For example, the drilling chip is more blunt, and some lighting light will be blocked when the short batch head is used. The grille grille is too thick, and foreign bodies are easy to enter the motor.
The biggest advantage is the dual -speed design. When you need to carry it, you can use it with multiple machines. Drilling and screwdriver tasks are fully covered. It should be reminded that its torque is fierce. Be sure to tighten the pinch, tighten, and tighten it to avoid slipping and wear the drill to reduce the accuracy. In order to improve the efficiency of work, you can match it with a fast -fitting head, as shown below.
It is convenient to change the batch header than the drill clip, and the concentricity is better than the normal extension rod. This attachment single purchase should be around 10 yuan, with more expensive sets. It is recommended to buy a set of more commonly used batch heads. Let ’s introduce the working principle of ScrewDriver to compare with the later 5228 to analyze their respective scope.
The picture above is the clutch of ScrewDriver. Use a torque cup to adjust the pressure of the spring. When the setting value is reached, the spring is compressed. The power input shaft and the output shaft are disconnected. To the sound. For the tight screws, because the peaks are one by one, there is no cumulative contribution, and the degree of screw fastening is almost not strengthened, as shown in the curve below. Therefore, the ScrewDriver with a torque cup is suitable for the occasion that requires precision to control the torque to avoid damaging the workpiece. For example, when uncertain torque can be affected by a certain kind of wood, try to find a safe and effective parameter with a torque cup.
This tool is also purchased from JD in 2014. It is 20 % off from the timing special area of the mobile APP, and the dual -electrical version is about 390 yuan. This year, JD.com was reduced by 30 during the 618th store celebration, and it was stronger. Coupled with several discount wool, it is easy to buy this price.
5228 belongs to the Rotary Impact ScrewDriver. It is more accurate to translate into a “rotation impact electric screwdriver” and avoid some purchase misunderstandings. The maximum torque is 100Nm, the rotation shock plus the influence of the influence, and in the hands of the experts, it is a professional screw tool with strong applicability.
The working principle is shown in the figure below.
The screws are pre -tightened by ordinary rotation, and the torque is low. After the pre -tightening is completed, the power output disk cannot be turned, and the power input shaft drives the metal shock block to continue to rotate. Each turns are turned, and the impact block is embedded in the output disk twice. High -frequency knocking continuously to achieve the effect of output high torque, that is, the screw still has a high tightening ability to the screw after the sound. Moreover, because the clutch frequency is high, the vibration is small, and the head is not easy to slip. The torque curve is shown in the figure below.
Its torque output is similar to a square wave. Because the impact block is heavier and has a certain inertia, each embedded output shaft can drive it to rotate a little, which can accumulate the effect of the screw and form a gradual increase in tightening. It should be emphasized that the Rotary Impact ScrewDriver has higher requirements for use experience. The relationship between the torque output and time is like a matrix curve. %, 5 seconds are close to the maximum, with curves with load torque output similar to the figure below. 5228 has an electronic speed regulator. Through speed control can also reduce the output power of the motor, combined with the impact time, it can reach a large range of torque adaptation, but personally feel that hundreds of experiences of screws in different operating conditions accumulate. Correctly grasp how much the speed switch is pressed and when to start and stop.
5228 maintains a large level of workmanship (not soft text, which is not available later). The shell is exquisite and powerful. The handle and the tail have imitation leather bag, and there are hanging rope holes. The grille grille is fine and good for the motor.
The batch head interface is fast -loaded, good at concentric, and convenient replacement. However, the manual reads the long batch head to adapt to the tail of the hexagonal handle. It is not easy to find except the original double -headed head. The use of conventional batch head trials can also work normally, that is, the quantity is a bit large.
5228 can basically meet the work of all screws and bolts, which is more suitable for hard twisting. In addition to home improvement, it can also be used in car maintenance and maintenance. Of course, there are many sleeves. It is a 4S shop. The author’s 5228 series was purchased in Jingdong during 618 in 2015. At 599 yuan, a 50 % discount coupon was added, and the real -time paid was about 390 yuan. Jingdong’s electric tools often circulate price reductions, and those who want to buy and don’t worry about keep paying attention.
The weight of the above -mentioned 12V lithium battery tools is well controlled at about 1 kg. It is easy to carry out and is not easy to use for a long time. The most important thing is that it is easy to control at work, reducing the probability of damaging workpieces.
1702 is “a hammer of a special lithium”.
Compared with other large products, failed to maintain a consistent level of workmanship, the plastic shell and assembly process are worse, and even the Devon logo is not printed outside the toolbox. In order to make full use of the rotation of the motor, the designer stuffed too many functions in it, which can achieve the Applications of Hammer Drilling, Drilling, and ScrewDriving, which is not proficient. According to the scope of the application of non -rope electric tools, it is best to hit concrete 24V, 12V 1702 6mm, 8mm is okay, and it will be strenuous. In order to increase the function, the designer set the interface of the hexagonal handle batch head behind the electric hammer. In order to avoid interference with each other, the steel balls of the electric hammer chip popped up high, and the positioning edges were short (compared to other light electric hammer), which caused the electric hammer head to connect very loose. The fixed length of the hexagonal handle is short, and the front is not supported, and the concentricity is not good. When used as a ScrewDriver, it is okay to screw a few screws. For a long time, the center of gravity is high, and it is more tired. In addition, it cannot be systematically compatible with various commonly used batch heads because the inner hole is too long. The figure below is a commonly compared comparison with its special batch head, which is difficult to match its special version.
If the purchasing demand is to do some supplements after the decoration, such as hanging paintings, lamps, installations, etc., basically use a 6mm swelling tube or 6mm expansion bolt to support, and below 8mm holes are enough. Or a worker who specializes in the Anshui electric line, to climb a lot of 6 ~ 8mm holes to fix the bracket. This light and rope is indeed a great advantage. In the scope of discussion in this article, it is not suitable for ScrewDriver.
The author’s purchase of it is based on the rich tool category and supplement the battery reserves. It is purchased during the 618 Jingdong store in 2015. 599 shall be reduced by 100 and 30 plus coupon wool, and the real pay is about 390 yuan. It is worth buying the news that Amazon Z -shot as low as 189 yuan (estimated to be sold at 1515). Pay attention to the follow -up, really shipped, it is a pity not to catch up, and there will be no price in the future.
Rope -free electric screw knife applicable range
The above figure lists the most applicable electric tool type under different functional and different diameter screw conditions, and the corresponding battery voltage (basically reflects the power size). It can be seen that the classification of tools corresponding to different needs is very fine, and it is suitable for friends to choose the corresponding product according to the needs. If you want to be in place, Rotary Impact ScrewDriver has a wide range of applications. After Fractal1 recommends Bosch GDR, it is worth buying Bosch Rotary Impact ScrewDriver. It is deeply affected by the electric tools and strong consumption. Talking about two lessons here, the most common words and cross screws are not designed for large torque. Such large torque electric tools are easy to break the screws. If you ca n’t get it, you ca n’t get new. You ca n’t even buy it even if you buy it. It ’s very troublesome. Now a small amount of screws is often manual, with spiny wheels, and the two -way umbrella teeth are also very fast.

Battery and charger
The battery of the 12V series of electric tools is universal. The batteries have been upgraded from 12V, 1.3AH to 12V, and 1.5AH power lithium battery, which is fixed in a buckle.
There are 5 electrode interfaces, which are positive and negative electrodes, C1, C2 electrode taps used in balanced charging, and a temperature sensor contact. The battery temperature is measured during large current charging discharge. It can be said that the charge and discharge protection protection is relatively complete. Some tools charger directly charged safer.
There are two types of chargers, which are 30 minutes ordinary charger and 15 minutes/70%fast charger. The 30 -minute model is configured in various intermittent work tools, such as drilling, hammer, 15 minutes/70%configuration in continuous consecutive consecutive configurations The tools of work, such as round saw, curve saw. The difference is shown in the figure below. Because the round saw is very consumable, if the battery is not much, it is necessary to charge quickly.
Batch head extension rod
ScrewDriver is best to keep concentric without extending rods. When there is a need, there are several common options below.
The top is the fast -loading joint. The best concentricity is the best, but it is convenient to change the head, but the general tools are not attached. The following two are sent with the attachments, which are integrated in the middle. The concentricity is better. The following is a split. When you find that the screw head of ScrewDriver shakes, it is best to check whether the extended rod is concentric. The split lever sent in the author’s tool accessory is not a good concentric.
Due to the lack of textbook -level tool applications, the author can only be evaluated based on incomplete use experience, and it is inevitable that it is inevitable. It is believed that through the exchange with a lovers worth buying tools, we can jointly enhance application experience. Use good tools to enrich life!
