The fast battery charging time is remarkable in comparison with our other tested products.

  • If you are drilling, you should wear hearing protection.
  • Use safety glasses to protect against dust.
  • The direction of rotation should be maintained until the screw head is firmly seated. Otherwise it may have a negative effect on the gear unit.
  • Stand behind the drill and lean lightly with the weight against the device.
  • Do not wear necklaces, scarves or loose clothes while working, because they can quickly get caught in the device.
 

How do we test at askgeorge.com?

Live and authentic: We get the devices into our Hamburg test laboratory. Here we take a close look at everything.

Each test is preceded by an extensive search:

  • Which suppliers are on the market?
  • What current products are there?
  • What are the comparison criteria?
  • What tests are we going to run?
  • What is the test procedure?

When everything's settled, we'll bring the devices to us. For each product the test procedure, the measured values and product properties are documented in detail. We create photos and videos. We evaluate the results for you, summarize everything in a test report and calculate the test grade.

Have fun!

Before the test, we defined practical requirements and the following test criteria:

  • Handling
  • Battery performance
  • Safety and security
  • Processing

In order to evaluate these criteria, we have defined several tests for the cordless drills. In the test different boards of different thicknesses are drilled through. Meanwhile, handling, operation and safety are checked. In addition, the volume is measured and the ergonomics are evaluated. For safety reasons, the devices are tested for automatic shutdown in case of overload. In order to test the battery performance, the time for charging and discharging the drills was measured.

All our test products have to drill through the same wood types and board thicknesses.

In order to avoid mistakes and to ensure the load of everyday use, each test takes place in several runs.

The test criteria are given percentages depending on their importance. The final score is then objectively calculated from the test criteria using an algorithm.

Product selection

Our product selection is based on observation of the current market. In addition to popular branded products, we also include insider tips in our selection. Criteria such as price and functionality are an important factor for us. The test field is determined by analysis and evaluation of customer reviews and external tests (e.g. Stiftung Warentest).

The devices are purchased anonymously or lent to us by the manufacturer. Retailers and manufacturers have no influence on the tests and our evaluation.

As soon as new relevant products come onto the market, our test field is extended by them. The new products are tested in the same way as the already tested devices.

Stiftung Warentest first tested cordless drills in February 2019. 17 drills went through the test. Of these, ten drills achieved a good result. The rest consists of three satisfactory tools, two sufficient and two defective ones. The two losers are inexpensive Obi tools from the Lux Tools series. The WX 175 from Worx came very close to first place. This result consists of three criteria: Function (50%), handling (35%) and durability (15%).

Three different materials were used for drilling: beech, sand-lime brick and steel. Almost no drill has a problem with wood. With the inexpensive Einhell and Obi tools it takes much longer to drill in wood, but with other materials they fail. The Makita machine is best suited for drilling holes in sand-lime bricks. The Worx rechargeable drill drills best through steel. Meanwhile, the efficiency of drilling was evaluated. With a full battery and after a charging time of 15 minutes it was checked how many holes can be drilled into the beech wood. Only three battery drills turned out to be really efficient. The Bosch Easy Drill 1200 was only able to deliver a poor result.

In order to assess the handling, attention was paid, among other things, to the comprehensibility of the instructions for use and the charging time. With four units, charging takes far too long in relation to the working time. In addition, the handling and user-friendliness of the drills were evaluated by three experienced craftsmen. The examiners also assessed the versatility with regard to the firm hold of the drill heads, LED equipment and adjustment options. Meister's MAS18xMZ was the most convincing in terms of handling.

Finally, the cordless drills were subjected to an endurance test. The devices had to drill in pine, beech wood or steel for 33 hours. In between there were phases of resting. This simulated a workload of more than 16,000 drill holes. After about ten percent of the testing time, the Obi devices were already in a state of disrepair. All cordless drills withstood the drop test on concrete from a height of one meter very well.

The products tested by Stiftung Warentest were not directly included in our practical test. However, there are overlaps in the evaluation of the cordless drills from Bosch, Einhell and Makita. A Metabo device was not tested by Stiftung Warentest.

To get started directly at home or on the construction site, a cordless drill, screwdriver or both are often available with various accessories. In most cases, these include a second battery, which enables work to be carried out without interruption because it can be charged with the first battery parallel to drilling and screwing and can be used directly if necessary.

A further accessory is a so-called hanging bracket for belt or trouser pocket. The cordless screwdriver can be attached to it so that it is not necessary to constantly put it down and pick it up - this guarantees back-friendly working.

Of course, the bits should not be missing from the scope of delivery. These are screwdriver blades for the screw head profile of the device. According to the bit holder on the cordless screwdriver, the holder is square or hexagonal. Depending on the shape of the screw, the appropriate bit is placed on the device. The bit itself is magnetic so that the screw cannot fall off.

Attachments are available for the drilling function. These are attached to the cordless screwdriver and held using a quick-release fastener. For example, attachments with a corkscrew function can also be purchased from retailers, so that the cordless drill can fulfil even more functions in the household and on the construction site.

Probably the biggest advantage of cordless screwdrivers is their wireless design. For an effective work no cable drum is needed and therefore there are no cables on the ground which could be tripped over. This contributes significantly to safety at the workplace or construction site. Thanks to the rechargeable battery, it is also possible to work in places that are not yet supplied with electricity.
A cordless screwdriver combines two functions in one device - drilling holes and screwing. For both activities the purchase of only one device is therefore necessary. Thanks to the variety of different models, the right device can be found for every project.

The basic equipment of the devices available today includes a two-speed gearbox so that the speed of the activity can be adjusted in the twinkling of an eye.
Most cordless screwdrivers are equipped with an integrated light which allows working in the dark - without any additional light source.
Many models also have a capacity indicator on the battery so you can easily estimate how long the battery will continue to provide power for drilling and screwing.
Integrated temperature monitoring and overload protection in most of today's commercially available cordless screwdrivers ensure safe operation and long service life.

The first step to use a cordless screwdriver is to press the switch, which is located on the handle of most models and can be operated by grabbing it. A charged battery is of course a prerequisite for the operation of the device. When the switch is actuated, control currents flows to the control electronics via conductor paths.

The components of the control electronics regulate the clockwise and counterclockwise rotation of the cordless drill as well as the torque control and motor rotation. The required current flows from the battery cells directly to the motor. So-called EC motors, which have no carbon brushes that cause wear, have higher efficiencies. The transmitted electricity generates a rotating field whose speed can be adjusted and regulated by the user of the cordless screwdriver via the control electronics. This results in the rotation of a multipole permanent magnet that produces sensor signals.

These signals reach the sensor, which in turn detects the position of the pole wheel and supplies the control and power electronics with information on speed and position. A gear wheel transmits the energy that is developed in the motor to the gearbox. From there it is transmitted to the tool holder via a drive shaft.

Depending on the application, a device with a suitable energy output should be used. The voltage and capacity can be calculated - the product of both gives the energy content of the battery in watt hours. The higher this is, the longer the device can be used for working.

The term cordless screwdriver is often used in our everyday lives. Is there a difference between cordless drills and cordless screwdrivers? The answer is yes. As the names already suggest, these are different devices that are used for screwing or drilling.

A cordless screwdriver, in contrast to a cordless drill, is used if you work with screws. It is practically the electronic version of a screwdriver, which can make the work much easier.
Cordless screwdrivers have a hexagonal holder for so-called bits - more about this later - or less often a square holder for sockets instead of a drill chuck.

Most cordless screwdrivers, like cordless drills, have a gear shift. The reason for this is the fact that lower speed is required for screwing than for drilling. Cordless screwdrivers are therefore not as powerful as cordless screwdrivers.
Over the years, the functionality of tools has become more and more important, so that devices have been developed that allow both drilling and screwing - so-called cordless screwdrivers.

These can be used flexibly, almost two devices in one.

The first hand drill with electric motor was launched by the company Fein in 1898. The same was done by the well-known electronics manufacturer AEG. The sensation at that time was that they were transportable devices. AEG further developed the electric drill in the following years and sold the first model with a metallic housing as early as 1901.

After manufacturing its one hundred thousandth drill in 1906, Fein specialised in the production of power tools - leaving the field to AEG. Two years later, the company introduced a drill with a pistol grip, which in the course of development up to the present time has been replaced by the ergonomically more advantageous T-handle. In 1912, the first devices with a built-in speed governor were introduced.

But other manufacturers also conquered the market. The well-known Japanese company Makita, for example, was founded in 1915 and started to further develop cordless drills. The patent for drills with pistol grip and pressure switch was secured in 1917 by the American company Black & Decker.

Several years passed and the German company Metabo also developed an electric drill, which was available from 1934. At that time AEG caused a sensation with the first double insulated motor and Black & Decker sold their one hundred thousandth model as early as 1950. Two years later Metabo introduced the practical quick-action drill chuck to the market. Atlas Copco, a Swedish company, developed the first pneumatic drill, which was available for purchase from 1954. One year later Metabo sold the first impact drill. The patent for the first electric drill with plastic housing was given to Fein in 1956, a company already mentioned at the beginning. Almost ten years later, AEG published the impact drill with two gears. Thanks to Metabo, the electronic automatic control system was added for the first time in 1969.

All these developments were followed by numerous optimizations of the functions within these companies.

The very first battery-powered drill was launched by Makita in 1969 - the battery-powered 6500D drill. Over ten years later, the first model with a nickel-cadmium battery appeared. Makita continued to develop and finally released the rechargeable drill with nickel hybrid technology in 1997.

In the same period, the German manufacturer BOSCH had become known and sold cordless screwdrivers with lithium-ion technology so successfully that over time they became the most purchased tool.

Makita took this as an example and started producing cordless drills with lithium-ion technology in 2005.

The competition of these companies over the years resulted in a multitude of different models of cordless drills with different technical features. Nowadays, every DIY store has several devices of this type in its product range. For unique applications in domestic use, devices are often available for loan.

As the name already implies, it is an electrical device powered by a rechargeable battery and is used to drill holes.

The devices vary in shape and size as well as in their technical features and the associated performance. Mini versions are available for domestic use, which are particularly easy to handle and have a compact design, so that they are ideal for situations where the working area is very limited.

In the daily life of a do-it-yourself enthusiast, different tasks arise. Typical examples are the attachment of curtain rods and the assembly of furniture. Both require holes to be drilled. Cordless drills are useful helpers who fulfil this purpose and therefore should not be missing in any do-it-yourself household.

The market offers a variety of devices from different manufacturers, such as AEG, Makita, BOSCH, Metabo, to name just a few examples. Both hobby do-it-yourselfers and professional users will find the right model for their projects and requirements.

As the consumer magazine Stiftung Warentest found out in 2015 based on a comparison, a good cordless drill does not necessarily have to be expensive. Criteria that play a decisive role in the purchase of such a device are, among others, the materials to be processed - because drilling holes in stone and concrete requires a different performance than drilling holes in wood - and the frequency of use - because if the device is only used occasionally in the household, it certainly does not have to be an expensive professional version.

Here you can find out exactly what a cordless drill is and how the device was developed, what differences there are to cordless screwdrivers, how such a tool works and which accessories are necessary for its use.
