In the home arsenal of tools, the impact drill takes pride of place. It cannot be said that an electric drill with a hammer is significantly different from a traditional tool. But its possibilities have become wider. The impact drill is even used successfully for non-traditional tasks, such as unscrewing rusty fasteners or driving upholstery nails into the wood frame of upholstered furniture.

What to look for when choosing
There are many models of percussion power tools on the market. Choosing the best impact drill, its future owner first of all expects to use it for its intended purpose in shockless mode, but when necessary, use its capabilities, for example, punch a hole for fasteners in concrete or brick.
An impact drill is more complex than a conventional electric drill. The design feature is the presence of an eccentric or drummer of approximately the same pattern as in a perforator. But, unlike a special tool, the impact mechanism of an electric drill is much smaller in size, strength and resource:
- Due to the presence of a hammer, the mechanical part of the drill wears out faster. If we compare the service life of the impact version and the usual one, then the classic electric drill will last much longer.
- The accuracy of drilling a hole with a drill is lower. This is again due to the presence of a drummer. During operation, the shaft on which the chuck is mounted experiences additional axial and radial loads, so an impact drill is not suitable for drilling thin and precise holes.
If you are lucky enough to buy a good quality branded impact drill, then its service life will be much longer than usual, and the runout on the shaft is less than that of budget and inexpensive electric drills. Therefore, when choosing a brand is very important.
Most well-known manufacturers of impact drills are trying to make the mechanical part optimally reliable, add a resource, perhaps even to the detriment of cost. The problem is that repairing the mechanical part of an impact drill or hammer drill is not cheap, and not every master can do it.
Even a simple replacement of a gear-toothed wheel pair requires professional-level skills, experience and knowledge. Therefore, when choosing this part of the impact drill, you need to pay special attention. All other parts - the electric motor, bearings, electrical wiring and even speed controllers, all this in the event of a breakdown can be replaced with new ones without any problems.
You also need to choose the right electric power of the impact electric drill. Models with an 800-900 W electric motor easily punch holes in concrete walls and bricks, they can drill holes in almost any material. But an impact drill for the home is not a hammer drill, its main task is to drill holes, which means that weight, dimensions and power should be moderate.
Therefore, the best impact drills with a power of only 500-600 watts. This will be enough for comfortable work. The capabilities of an impact drill are enough to drill holes and flash holes in concrete (brick) in 9 cases out of 10. For super-precise drilling, you can use the machine. The capabilities of a desktop tool cannot be compared with a manual one, especially a percussion type.
Moreover, many owners prefer low-power cordless electric drills. They are easy to use, light in weight and have a huge torque in order to drill (punch) holes or unscrew a rusty screw. In many cases, craftsmen become so accustomed to cordless impact drills that they, in fact, replace the entire household tool - from conventional electric drills to classic screwdrivers and screwdrivers.
Widespread use is also facilitated by the universal type of cartridge. In some models of impact drills, it can be removed and replaced with a special one. That is, you can put a clamp for bits or replace it with a drill chuck.
There is also a nozzle for tightening nuts and even for making cuts in sheet metal. Sometimes the manufacturer adds a couple of such devices to the impact drill kit, but most enterprises seek to reduce the price of their products, so they save on replacement accessories and nozzles.

Rating of the best impact drills
For a correct comparison of models, it will be correct to use the same basic characteristics. When choosing an impact drill, you must additionally pay attention to:
- Power and type of electric motor. Usually in cordless electric drills it is collector, in expensive brands it is brushless.
- The diameter of the tool that can be mounted in the chuck. The size of the cartridge itself. It should not be too large, since the additional inertia due to the heavy holder strongly gives into the hands when working in shock mode.
- Battery capacity and operating time of the electric drill on a single charge.
- Number of speed-torque settings. Typically, a percussion instrument uses a smooth electronic adjustment rather than a mechanical switch.
- The presence of a reverse. This is a mandatory option, without it, buying an impact drill loses its meaning.
- Manufacturer company.
Almost all manufacturing companies pay special attention to fine-tuning, fitting and adjusting the mechanical part of impact electric drills. The mechanics are carefully adjusted and adjusted during the assembly process. Therefore, it makes no sense to hope for a simple replacement of the impact gear in a cheap Chinese drill. Such a tool does not work for a long time.
Each developer has his own secrets on how to make the impact mechanism more reliable, and the electric motor compact and high-speed. Many companies in the production of impact models of electric drills and rotary hammers have made their name in this area. Makita is an example of this. Her tools are today considered a model for copying and developing your own models.
Model Whirlwind DU-25A-850
A typical mid-range model, but in the review it is one of the best impact drills in terms of price-quality ratio. The design was developed in the Russian Federation, but the tool is made in China.
With a brush motor power of 850 W, an electric drill costs only 2250 rubles. True, there is no soft starter in the design, so each press of the button significantly hits the hands of the master.
Characteristics:
- Drilling diameter - up to 13 mm for metal and brick, 10 mm - for concrete.
- Weight - 1.9 kg. Despite the high power, the tool turned out to be light.
- There is a smooth adjustment of the rotation speed of the drill.
- Standard collet chuck with key lock.
According to reviews, most owners purchased the Whirlwind as a cheap tool for working at a construction site for one season. For many, the impact drill lasted 3-5 years, despite the fact that the manufacturer gives a 1-year warranty. They note a comfortable handle and simple maintenance. If you change the brushes in time and do not abuse the perforation mode, then the electric drill will last several times longer than the warranty period.
But it is unlikely that this model can be used as a professional one. Despite the simple design and low weight, the capabilities of the Whirlwind are enough for a maximum of single cases of homework.
Intreskol DU-16/1000ER
This is not a budget option for an impact drill, especially considering its cost and power of the electric motor. The manufacturing company equipped the tool with a 1000 W motor. For a hammer drill, this is a common thing, but for a drill, a thousand watts is too much. The total weight of the impact electric drill is 3.8 kg.
This model uses an aluminum alloy frame and gearbox housing. It is possible to note a heavy mechanical reverse switch, a powerful chuck, reinforced bearings. An impact drill punches a hole in concrete up to 20 mm, for a brick 35 mm.
Sometimes the owners of Intreskol DU-16 / 1000ER voice their claims that during operation the metal case of the gearbox is very hot. This is normal, this is a technological technique that ensures stable cooling of the gearbox transmission pairs. Much worse if the casing were plastic, and the grease would burn out under heavy load due to overheating of the gears.
Interskol DU-16/1000ER belongs to the middle class, an impact drill will appeal to those customers who like massive and reliable power tools.
Ryobi RPD2-1000K
A fairly heavy semi-professional model with an aluminum alloy body with reinforced walls in the gearbox area. The weight of the electric drill is about 3 kg, so the return to the hands during the perforation process will be minimal.
Main characteristics of Ruobi RP D2:
- Brush motor power - 1010 watts.
- Weight - 2.9 kg.
- Keyless chuck, largest drill diameter 13 mm.
- Impact drilling can make a hole in concrete 15 mm, in brick 20 mm, in metal 13 mm, wood 50 mm.
- There is a reverse function, switching is performed by a switch on the gearbox housing.
- The model is two-speed, but one of them, according to the instructions, is recommended for clean drilling, the second, with reduced speed, is used to work in perforation mode.
The Ruobi impact electric drill is distinguished by its relative simplicity of design, reliability and durability. The manufacturing company can complete the impact drill with a standard collet chuck or install self-clamping versions of the puncher. Due to the high power of the striker, keyless chucks often break before the end of the warranty period.
The price of the model is 9 thousand rubles. rub.
Daewoo Power Products DAD650
Today it is one of the suitable options for an impact drill if a lightweight and accurate tool is required. The power of the electric drill is only 650 watts. This is enough for a tool of only 2.0 kg to punch holes in concrete up to 16 mm. The diameter of the drill that can be inserted into the chuck is 13 mm.
The impact electric drill is equipped with a reverser, an electronic speed control unit. Despite the fact that the design uses mainly impact-resistant plastic, the drill itself has good resistance to impact and even tolerates a fall on concrete.
The strength and rigidity of the frame is so high that the electric drill can be installed in a drill stand. In this case, it can be used not only for drilling a hole, but also for working hardening of the metal surface. For example, after welding a reinforcement or repairing a crack.
The main difference between the Power Products DAD650 is the high build quality. The manufacturer Daewoo issues a three-year warranty on an impact drill, subject to registration of purchase and operation in drilling mode for at least half of the total time. It is clear that this condition concerns targeted purchases by enterprises for their workers.
The price of an impact drill is 2700 rubles.
Metabo SBE 650 (BZP)
One of the best professional quality impact drills. Metabo hand tools have always been distinguished by high reliability, good design, acceptable build quality.
Main characteristics of Metabo SBE 650:
- Drilling diameter in concrete - up to 14 mm, in brick 16 mm, in steel 13 mm.
- Motor power 650 W.
- Electronic speed control is provided using the proprietary Vario system.
- There is a switch for the direction of rotation of the cartridge.
The Metabo SBE 650 impact drill is equipped with a double chuck. Inside the clamp, at the bottom, there is a hexagonal male lock, into which a bit can be inserted. Thus, an impact drill can be used to tighten self-tapping screws or loosen rusted fasteners.
The price of a Metabo SBE 650 impact drill is at least 10-11 thousand rubles. rub.
Makita HP1640
The engineers of the hand tool manufacturer initially design their products for the most adverse operating conditions. Therefore, almost all Makita tools have a reputation for being unkillable.
Impact drill model Makita HP1640 is one of the simplest and most affordable, only 7000 rubles. At the same time, the power of the electric motor is 680 watts. The reducer and striker are made according to the traditional technology of forging, heat treatment and nitriding of the working surface.
Specifications Makita HP1640:
- Weight - 2.48 kg.
- Chuck with key.
- Electronic speed control.
- Drilling diameter in concrete up to 13 mm, in brick up to 16 mm.
The only drawback of this model is the lack of an electronic rotation stabilization system. Usually in branded drum models, such a system is installed by default. Although, according to many masters, such a system is not relevant for electric drills with a hammer.
In this case, the company deliberately abandoned its use in order to make the impact drill more reliable and at the same time reduce the cost of its production.
AEG SB2E 1100RV
Impact drill of the famous German brand. But most of the instrument is made in China, so you can only buy a licensed copy of the "German" on the market.

The price of the model is 13.5 thousand rubles. rub.
The best cordless impact drills
Many sellers of hand power tools classify electric drills with impactors and batteries as a separate variety, with impact mode as impact screwdrivers. Therefore, if the desired model is not found in the section of impact drills, it makes sense to look for a tool in the category of cordless screwdrivers. The battery powered tool has its advantages:
- Easier to use, no cord.
- Can be used to work in the country, anywhere where there is no electricity.
