TOP 5 great cordless rotary hammers with brushless motors

With the versatility of the Einhell HEROCCO rotary hammer, everything is just fine. It can work in any mode. The tool can drill (with and without impact) and hammer in any way (with or without turning the drill). Moreover, the rotary hammer can even be used as a screwdriver, because it comes with a special magnetic adapter for bits, and the rotation speed is easy to control by changing the pressing force on the start key.

The brushless motor makes efficient use of the energy drawn from the battery. Therefore, the rotary hammer can hammer quite strongly (impact energy 2.2 J) and quickly drill (speed reaches 1200 rpm), rotating a drill or drill with a diameter of up to 20 mm, and tighten fasteners tightly (torque 18 Nm). There is enough energy even for LED backlighting, which illuminates the work area with bright light. In the case with the tool there are accessories: an additional handle and a depth gauge.

The disadvantages should be recorded as the mediocre operation of the anti-vibration system. It works somehow and dampens the vibration only partially. Therefore, this rotary hammer is not suitable for more or less long-term work. However, nothing else can be expected from a household class instrument.

Einhell HEROCCO is one of the most inexpensive models among cordless rotary hammers. But, while rubbing your hands at the low price, remember that the battery is not included, and you will have to buy it separately (the manufacturer recommends using a battery with a capacity of 3 Ah or more). Buying this rotary hammer is most beneficial for those who already have 18-volt batteries from other types of Einhell cordless tools.

The Metabo PowerMaxx BH 12 BL 16 demonstrates how small a rotary hammer can be with state-of-the-art technology. It weighs only 1.7 kg (together with a standard 2 Ah battery) - quite a bit by the standards of this type of power tool. This was achieved thanks to a super-compact brushless motor. Naturally, such a miniature perforator cannot be powerful (the impact energy is only 1.3 J). Yes, and he does not know how to work in chiseling mode, like a demolition hammer. But the light weight allows you to effortlessly hold the tool in your outstretched hand.

The perforator has an anti-vibration system (the handle is “suspended” on two hinges) and a safety clutch that disengages the engine and cartridge when jammed. The keep-rev function makes operation easier and more convenient. There is a backlight to illuminate the space in front of you. In the case with the tool, in addition to the hammer itself, there is a removable side handle, a metal drilling depth limiter, a charger and two batteries at once.

Due to its lightness and compactness, this rotary hammer can be especially useful for craftsmen who perform small volumes of drilling operations in concrete and brick. If you drill holes for fasteners in walls and ceilings and often work under the ceiling, then such a lightweight tool is simply indispensable. But with complex tasks, he will not cope because of his small power.

By the standards of network punchers, an impact energy of 2.8 J is the norm. But for battery models, this is a very decent indicator that deserves admiration. It was possible to achieve such characteristics by equipping the Makita DHR280Z with a modern electronically controlled brushless motor. The tool turned out to be not very light (3.1 kg - approximately like network analogues of the same power class), but completely autonomous. Now you can drill and chisel brick or concrete on objects that are not connected to the power grid, without carrying bulky generators with you.

The manufacturer has taken good care of the reliability of the tool. The rotary hammer differs in high resistance to dust and moisture. But at the same time, they did not forget about the users. In order to make the work comfortable and safe, the device is equipped with an anti-vibration system and a disengaging clutch. The beat frequency can be changed by turning the speed control. The electronics automatically maintains the set chuck rotation speed. Eco mode with "soft impact" saves battery power by reducing the impact force at times when the drill or drill does not experience resistance. There is an LED light for working in the dark.

Makita DHR280Z is sold as a "carcass". That is, the charger and battery are not included. Please note that this rotary hammer is a 36-volt device. It runs on two 18-volt batteries (other Makita tools work on the same batteries of the LXT series: screwdrivers, grinders, renovators, etc.). The tool will not work from one battery.

With a useful power of 425 W and an impact energy of 2.6 J, Bosch GBH 18V-26 is not inferior to conventional corded hammers. It easily works with large-caliber drills and drills (diameter up to 25 - 30 mm), as well as crowns up to 68 mm in size. Cordless Bosch successfully copes with drilling, chasing, drilling holes for anchors, punching niches for electrical panels and boxes, and other tasks that are typical for medium-power rotary hammers.

According to the "stuffing" of this rotary hammer, there are not so many competitors. It is equipped with an active vibration absorber, a safety clutch for "kickback" protection and LED lighting. The electronics that control the operation of the brushless motor are able to maintain speed, taking into account the load on the tool. The "soft hit" feature limits the amount of chiseling force when the drill or auger tip hits relatively soft or brittle material to conserve battery power and prevent unnecessary cracking.

The tool comes with a case, charger and two batteries at once. At the same time, regular batteries have a large capacity (6 Ah) and provide long-term operation on a single charge.

The only significant drawback of this model is the price (high-quality network punchers of the same power class cost three times less). Therefore, if you already have 18-volt Bosch batteries and a charger for them, then it makes sense to buy a “carcass” Bosch GBH 18V-26 Professional 0611909000, which is sold without a battery and therefore costs much less. And for relatively simple tasks, you can take the Bosch GBH 180-LI Professional 0615990L6J with an impact energy of 1.7 J.

Compact and not very heavy (3.1 kg), the DeWALT DCH273P2 can easily compete with other mid-range rock drills. It has a brushless motor that delivers 400W of useful power and a reliable impact mechanism that hits with an energy of 2.1J. These characteristics are quite enough to drill and drill holes in brick and stone, punch shallow strobes, knock down plaster and tiles, and perform other construction and assembly tasks.

In the perforator chuck, equipment is attached that has SDS + standard shanks: drills and drills, chisels and peaks, chisels and crowns. During operation, you can turn off the impact or lock the spindle to prevent the chuck from turning. In case of jamming of the drill in concrete, the release clutch is activated. Users especially note the ergonomics of the tool (comfortable handles and correct weight distribution), as well as the effective operation of vibration protection and well-made lighting. The rotary hammer comes with two large-capacity batteries (5 Ah each), a charger and a case.

Despite the rather high price, the DeWALT DCH273P2 perforator is in demand among builders. It is bought mainly by specialists who are engaged in the installation of stretch ceilings, plumbing, electrical and low-voltage networks, air conditioning and ventilation systems - that is, those craftsmen who need an autonomous tool for work that can make 50-100 holes for anchors and dowels on a single charge in brick or concrete.
