The modern range offers many different models from leading manufacturers. How not to get confused in such a variety and make a purchase that will last more than one year? What to look for when choosing? Which battery is a screwdriver better? – In this article, you will find answers to these and other questions and will be able to understand which tool is best for you.
Before deciding which cordless screwdriver to choose for one purpose or another, you should study the criteria that matter, and which ones can be completely ignored.
And the main parameters for choosing a screwdriver are:
- Manufacturing firm;
- Dimensions, weight;
- Ease of use;
- Battery type and capacity;
- Torque and shaft speed;
Depending on these characteristics, the cost of the tool is determined. But more expensive is not always better. So, for example, if you plan to use a screwdriver extremely rarely and exclusively for domestic purposes, additional functions, increased power and a high-capacity battery are unlikely to be as useful as compact dimensions and low weight. Therefore, if you want to purchase such a tool, you first need to decide for what tasks it is needed.
For home or industrial use
Professional tools are superior to household tools in many ways, and screwdrivers are no exception. But the price for professional models is appropriate. The significant difference lies in the torque (130 Nm vs. 15 Nm). It should be understood that for working with ordinary nuts, screws or self-tapping screws, the power of a household appliance will be quite enough.
Another advantage of more expensive models is fast battery charging (up to 1 hour). Together with such a device, you can save your time, and also not wait for 3-5 hours until the battery is charged. If charging time is not an important criterion for you, an ordinary amateur screwdriver will meet all your expectations.
Batteries in a screwdriver are the main source of power; without a normal battery, not a single device will work normally. Since we are talking specifically about battery devices, you need to have an idea about the types of batteries. Distinguish:
- nickel-cadmium batteries;
- nickel-metal hydride;
The first type of battery is becoming less and less popular over time, because it contains an allergenic substance. However, tools with such a power source can still be found and bought. Among the advantages of a nickel-cadmium battery, it should be noted the ability to endure even extreme cold and withstand about 1000 charges. A feature and weakness is the loss of capacity with each charge.
The second type of battery is lightweight, but not as durable. On average, its operating time is approximately 500 charges.
By choosing a tool with a lithium-ion power supply, you get a powerful, reliable and durable device. Like nickel-cadmium batteries, such batteries are not afraid of the cold, and they have no memory effect, i.e., there is no limit for charging and discharging in this case.
Buying a battery separately is very expensive and unprofitable, so when choosing a screwdriver, first of all, pay attention to models that come with not only the main battery, but also a spare battery. It may not be useful to you soon or not at all, but in the event of a failure of the main battery, you can immediately replace it quickly and free of charge.
Torque and speed
The maximum torque is a certain load threshold of your device. It is designed to ensure that the engine serves you as long as possible and does not fail ahead of time. As mentioned above, depending on whether it is a household or professional instrument, this value can fluctuate over a wide range. When choosing a screwdriver, keep in mind that less than 10 Nm is almost always enough to drive screws, and if you also want to drill holes, a high torque drill driver is a good buy.
When figuring out which cordless screwdriver is better, it is important to note that you will find a torque limiter on the body of a quality device. With the help of such a regulator, you will reduce the wear of the nozzle and ensure that the screw goes to the required depth. And the more adjustment steps, the better.
Shaft speed is another important parameter. A speed of 400-500 rpm is good for screwdriving fasteners when a fast shaft movement (up to 1300 rpm) is suitable for drilling. If you want to purchase a universal device, pay attention to the presence of a speed controller.
Don’t know which one to buy? – Opt for one that comes with a spare battery and more attachments. Decide if you need a flashlight for work. It is very convenient and practical if the tool is sold in a compact suitcase. So you can store the tool and all the attachments, as well as easily take it with you.
The presence of certificates and documents is a guarantee that confirms the originality of the manufacturer and high quality. There are many fakes being sold today, so looking at such papers will protect you from being deceived.
If the product is really of high quality, and its characteristics satisfy you, it makes sense to consider the device in more detail. Take it in hand, try all the buttons and switches. Many hardware stores also have special test benches. Do not miss this moment, because only in practice you can feel all the strengths of the device.
Looking at a window in a specialty store, you will see a dozen or more manufacturers. Bosch (Germany); Makita (Japan); AEG (Germany); Hitachi (Japan); Black & Decker (USA); Sparky (Germany) – not the whole list of popular brands. But which company is the best?
In fact, they all differ in their features, advantages and disadvantages. Against the background of most manufacturers, it is worth noting the top three – Bosch, Makita, Hitachi. Products of these brands have decent build quality, functionality and durability. By choosing one of these manufacturers, although you will overpay extra money only for the brand, you are unlikely to regret your decision.
Mini-review of popular models
So, having understood how to choose a cordless screwdriver, we will try to identify the advantages and identify the disadvantages of popular models from well-known manufacturers. Let’s take a closer look at the following devices:
- Makita 8281DWPE;
- Hitachi DS12DVF3;
- Bosch GSR 12-2.
The first model is an excellent tool, equipped with a lithium-ion battery and a shock function. Its price is 5-8 thousand rubles, which is consistent with the quality and capabilities of a screwdriver. The kit comes with two batteries and a powerful charger that can fully charge the battery in just one hour. The rotational speed is divided into two ranges: up to 400 and 1300 rpm, respectively. Among the shortcomings, it is worth noting the low battery capacity and a weak cartridge for a tool with a percussion function.
This screwdriver is somewhat cheaper than the first model, its cost ranges from 3-6 thousand rubles. The tool differs, first of all, in a very exotic appearance, which is difficult to fake. It is also able to effectively protect the instrument in case of a fall. The kit includes a flashlight, a charger and a 1.3 Ah battery that charges in just one hour. Among the weaknesses, one can note the obsolete cartridge, but it copes with its work without problems.
Bosch GSR 12-2
A very common model, it has a traditional appearance for this manufacturer and has two rotation speed ranges (up to 400 and up to 1200 rpm). Its cost is almost comparable to the model above. Features include a keyless chuck, cushioned grip and 25 steps of torque. In the package you will find two batteries with a capacity of 1.5 Ah.
Video tips for choosing
If you have any questions, we recommend watching this video. It explains in detail which is better to buy a cordless screwdriver.
Which cordless screwdriver is better, be it Makita, Bosch or another manufacturer – it’s up to you to choose. Remember that it is not at all necessary to choose expensive models, because for home, repair or basic household needs, a less powerful model will be more than enough. If you need a tool for every day, we recommend choosing professional models. They cost a lot more, but this price is well justified.
Now you know how to choose the right cordless screwdriver and you can easily make a good purchase at minimal cost!
