Electric drill is a tool for drilling holes in hard and soft materials. It is used in construction, finishing, carpentry, and locksmith work. The standard electric drill is suitable for drilling metal, wood, or drywall. The impact drill can handle concrete, brick, or stone. With special attachments, this tool is also used for grinding wood and plastic.
The impact drill differs from the non-impact drill in that it is suitable for drilling holes in strong materials, such as concrete, stone, or brick. This makes it look like a hammer drill. However, the cost of an impact electric drill is lower than that of the cheapest hammer drill. The capabilities of such a tool are limited, for example, impact models can not withstand constant intensive work with hard and dense materials. If you use an electric drill only for concrete or brick, it will lose its drilling accuracy or simply fail. If you have a need to regularly drill dense and strong materials, then instead of a drill on concrete, we recommend buying a hammer drill.
TOP-5 impact drivers to buy in 2022
Choose one of these impact drivers and you will get great results.
Everything you need for an amateur drill is a here-an an ergonomic handle, a good balance, quite a decent power of 680 watts. The speed control, however, is more suitable for the big-handed owner – personally, I found the slider placed on the sidewall convenient, but with a smaller brush size in the upper-most position, it will be difficult to grasp it with a short thumb. The same can be said about the weight-1.8 kg for someone you can use with one hand, someone will not interfere with an additional handle.

Weight 1.8 kg.
The metal housing of the gearbox initially attracted attention – although it is a rather fragile grade of silumin, a clear application for a good resource at high loads. In terms of its power (850 W), the impact drill has almost caught up with the leader of the best rating, and in terms of weight, it is completely similar to him. So in the amateur models presented to your attention, the competition for the second place was tough, although it is as a shock drill that is less successful, won by a small margin precisely for ergonomics with the most frequent household work. If the shock mode is supposed to be used more often, then this model gets a certain advantage.
Not comfortable for big hands.
Ergonomics - under the index finger is the trigger, above it is a transverse reverse switch, equally convenient for both left-handers and right-handers. The choice of the operating mode (screwdriver/drill/impact drill) is made on the ring located under the usual tightening force limiter.
The maximum torque of 63-newton meters is slightly more than in the "gentle" mode, but after all, it has a second maximum torque mode, which has nothing to oppose. In the shock mode, the lower weight of the screwdriver immediately affects – a one-and-a-half kilogram fairly itches in the palm, since the rubber pads on the handle are thin and do not save much from vibration. The battery is drained faster, as it lags behind in the capacity.

For both left-handers and right-handers.
Note the indisputable advantage of the impact drill in the form of a brushless motor (from the tools that got into the rating, LUDYVI was the only one with a motor of this type) - this is an increased resource (no brushes – no problems), and reduced energy consumption. As a result, having the same five-amp battery LUDYVI on one charge will work longer.
The three-position speed controller seemed an interesting solution. After the usual two-positioner, at first, it is unusual... but then you realize that this "average" mode is often not enough.

Reduced energy consumption.
Not the most powerful model.
It is equipped with a quick-release chuck, which allows you to quickly replace the tooling directly at the workplace, without distracting from the production process. This powerful tool is able to combine drilling and impact drilling modes. With its help, the master will be able to perform the widest range of construction and repair work.
Not the best battery.
How to choose an impact driver?
This section lists the main characteristics of electric drills that you will find with each tool:
Power-the higher this characteristic, the more heavy loads the tool is able to withstand. Manufacturers produce wood drills with power ratings in the range of 300-1500 watts. In household models, this characteristic rarely exceeds 800 watts. This is enough for drilling materials no stronger than bricks, such as wood or drywall. If you need to drill concrete, we recommend buying a more powerful drill.
Number of revolutions per minute-this parameter determines the speed of drilling holes and the smoothness of their walls. In addition, high speeds are needed for grinding, polishing, and drilling with impact. At idle, the motor of some electric drills develops up to 3500 rpm. For screwing in screws with a drill-screwdriver, the frequency of 400-500 rpm is enough. For drilling dense material, you need a tool at 1200-1300 rpm and higher.
Drilling diameter-manufacturers specify in the instructions for the tool the maximum width of the hole that the electric drill makes in wood, metal, and brick. It is determined by the diameter of the drill. If you insert a drill bit with a diameter larger than the one recommended by the manufacturer, the engine will overheat and fail.
Torque - this characteristic determines the level of load that will be applied to the tool motor during operation. For a universal electric drill, it is desirable to choose a high torque - at least 30 NM. A tool with such indicators will show itself equally well in drilling and in screwing screws. If you choose a home wood drill, choose a model with a torque of up to 30 Nm.
Accordingly, when choosing a suitable model, it recommends relying on these indicators.
