Hammer drills are more versatile, as they can perform the tasks of both a drill and a jackhammer, so these tools are more widely used and popular in repair and construction. It is not at all surprising that there is always a demand for this segment of equipment and at the same time new brands, products and questions associated with the purchase of such products appear. We propose to consider the rating of the best rotary hammers in 2021, which we have compiled taking into account the main tasks that ordinary buyers face. To begin with, consider the classification of such devices by weight:
- Lightweight: they weigh up to 3.5 kg, but their maximum power does not exceed 800 watts. Such equipment is purchased to solve everyday problems (for working with plumbing, chipping tiles, installing sockets, etc.);
- Medium – has a power of up to 1000W with a weight of up to 7.5 kilograms. They are already managed by craftsmen who specialize in the construction of communication networks and electrical work. Enough power to drill holes, including wiring, but not for construction;
- Heavy: they have a maximum power for drilling holes over 10 cm, but weigh about 8 kg or more. Oversized tools are equipped with a shock absorber to reduce vibration when drilling stone, concrete and other dense materials.
As you may have guessed, our assessment will mainly feature light and medium hammers, which may also differ in external and internal design:
- Vertical hammers are smaller tools that are easier to use in the right environment (where space is limited). The advantage of this design is also better cooling of the power plant and wear resistance;
- Horizontal drills are less powerful but better for spot repairs, including chipped tiles, etc. The advantages of this design include a good balance and a solid body.
The best electric rotary hammers
If the area where you plan to use the tool has access to a power outlet, a corded impact drill is the obvious choice. There is no need to worry about the battery ever running out and there is clearly more power headroom. In this selection, we have presented the best solutions for the home in terms of value for money. There are also semi-professional solutions that have a wider scope. They are used by many home craftsmen in the repair of large residential premises.
The list of good hammer drills for the home opens with the inexpensive DeWALT D25133K mesh model, which attracts with its competent ergonomics and good impact force of about 2.6 J. This series does not include a case or bag, unlike the D25133K, which explains the more democratic price tag. As for the technical characteristics, they really do not differ. The DeWALT product is excellent for working with hard materials such as metal and high-strength polymer plastics, which can be attributed to the 800 watt power plant. The motor is protected from dust. The SDS Plus class keyless chuck ensures ease of maintenance, but that hasn’t stopped the company’s engineers from packing the device into a compact body with a total weight of 2.6 kg. Holes up to 2.6 cm in diameter can be drilled in concrete.

The best cordless rotary hammers
In terms of performance, many models are no longer particularly inferior to their mains-powered electric counterparts, but are more expensive. However, in the absence of access to a retail outlet at the facility where the equipment is used, overpayments are indispensable. Fortunately, this issue has been resolved. If you are worried that the battery will run out quickly, look for tools with an extra battery included. These products are also featured in our selection, based on current trends and expert opinions.
The Bort BHD-18X-BLK model replenishes the power of domestic rotary hammers, operating on a 3 Ah battery with an output power of 18 V. The kit includes two batteries, but their capacity is clearly not enough for serious work. For domestic needs, an impact energy of 1.7 J and a performance of about 5200 beats per minute are sufficient. The cartridge type in this model is SDS+. To communicate the excellent quality of the brushless motor, the presence of a light and a case are included. For the price, this is definitely a good piece of equipment. Experts note the minimum amount of heat loss, as well as the optimal number of modes for living conditions – drilling and stamping / stamping. In turn, the backlight allows you to use the tool in hard-to-reach places with poor artificial or natural lighting.

Among the whole variety of cordless hammers for home use, we really like the relatively inexpensive, but good model of the Interskol PA-24 series with an SDS Plus cartridge with a good lithium-ion battery. At the same time, the device supports three operating modes, which indicates a very large amount of equipment operation. In this series, a brushless motor is implemented, which allows for a 30-40% increase in efficiency compared to budget counterparts. It is worth noting that the kit includes two batteries and an additional pen at the same time. Another advantage of the hammer drill is a metal depth gauge, which helps a lot when the cartridge is “buggy”, but this is also rare.
- well drills concrete;
- good protection;
- Comes with a convenient carrying case;
- affordable cost.
- sometimes the cartridge fails.
In search of the best repair solution, many customers have opted for the high quality Makita DHR202Z cordless rotary hammer with screwdriver holder.

How to choose a good perforator?
First, let’s talk about the main parameters that must be considered when choosing a hammer drill, after which we will consider the most common questions:
- Power: optimally from 400 to 2000 W, depending on the purpose and class of equipment. For the home, light rotary hammers with a power of up to 1000 watts are enough.
- Hit frequency is the number of moves an attacker makes per minute. This number usually ranges from 0 to 5000 matches. However, the frequency is lower than that of a simple drill, since a lot depends on the impact force, keep this in mind.
- Spindle speed: The speed of the tools depends on this indicator. With frequent use, you should focus on high values u200bu200bin the region of 1500-2000 rpm.
- Number of modes: for home use, two are enough (drilling and punching / stamping), and for professional work, a separate type of work is also needed (perforation).
- Drilling diameter: can be indicated by different numbers, as much depends on the equipment and type of material. For example, concrete drilling performance is usually compared. Here, when using a crown, the indicator can vary from 1.2 cm to 16 cm, and in the case of a drill, from 1 to 8 cm.
- Hammer weight – the classification presented at the beginning of the assessment must be taken into account, as much depends on the tasks at hand. For everyday life, a medium-weight device (up to 4 kilograms) is enough, but for construction, 8 kilograms can be the norm if you plan to cut channels, drill a hole, and so on.
Tips for choosing a puncher from experts
At the end of the publication, we want to answer readers’ questions and give qualified advice on choosing a puncher:
What is the difference between electronic reverse and brush reverse, which is better? It is important to understand that the reverse is used to change the direction of the drill, which is responsible for the ease with which it can be removed from a particular material. The electronic version implies a loss of power, and the brushes themselves lose their properties faster. This inversion is more common in household budget models. In more expensive devices with brushes, it switches vice versa and the power does not decrease. But the implementation of this technology will require more effort and finance, respectively, the cost of the perforator will be higher. How important is a safety clutch? For ordinary users, this is a necessary element, not a recommendation. Firstly, this system works if the equipment gets stuck in the armature or beam. The clutch will engage preventing you from continuing with the installation. Another advantage of this component is that it protects the operator from unexpected injury. What is anti-vibration protection for? This system is rarely found in inexpensive rock drills. Otherwise, we see primitive inserts and rubbers, which are of little use. Active protection is used in professional solutions and is a strong counterweight that can absorb vibrations. This is very important if you plan to use a heavy hammer drill for several hours, otherwise your hands will quickly get tired and there will be a chance of developing the so-called tunnel syndrome (hands begin to shake without anyone’s desire). What configuration items should be considered? When choosing your first hammer drill, it is best to choose the largest set that can only be obtained within the budget available to purchase the product. As a rule, another handle and a limiter are included as standard. Less common are the drill chuck adapter, housing, and replacement brushes. You will also need a wrench and base size drill bits. It makes no sense to overpay for goods not listed in this block. What type of cartridge is best? You need to rely on the hardware you will be using. SDS-plus chucks are used in small household solutions, and the shank is around 1 cm. SDS-max chucks are installed in semi-professional and professional rock drills (medium and heavy tools), which feature a modernized nozzle fixation. You definitely shouldn’t rely on SDS-top as this cartridge is used in “old school” rotary hammers which are very outdated.
