General description of Makita rotary hammers
The history of the Makita company goes back almost a hundred years. The manufacturer’s product line includes many tools, but rotary hammers occupy a leading position among them in terms of the number of positions presented. Among them are models with mains power and battery power.
Based on functionality, devices are divided into models with one, two and three modes. In the first case, only hammer drilling is performed, in the second, the function of a conventional drill is added, in the third, all operating modes are possible. Also, rotary hammer models differ in weight into light, medium and heavy. The light category is devices that do not exceed a weight of 3 kg; they are suitable for performing small household work. Medium - up to 5 kg, these models are suitable for working with hard materials. Heavy category - from 5 kg, performs the function of a jackhammer.
Makita devices are divided into two types according to the fastening of equipment - SDS-Plus and SDS-Max. Lightweight class 1 and 2 rotary hammers are equipped with SDS-Plus chucks. They are suitable for drilling holes up to 30mm or for enlarging holes with a hollow core drill up to 68mm in concrete and 80mm in brick. Heavy third-class rotary hammers are equipped with SDS-Max cartridges. Suitable for drilling holes up to 52 mm, working with hollow cores up to 160 mm.
The location of the motors in the device also differs, which can be vertical or horizontal. Vertically located engines give the device a longer operating life, which is due to some design features. Such devices have a gearbox that reduces the load on the motor. In this modification the engine has large area, which contributes to better cooling. The advantages of a horizontal motor arrangement are the more compact dimensions of the device, a familiar shape, convenient for home use.
Main characteristics of Makita rotary hammers
Impact energy - this indicator is measured in joules and determines the ability to work with certain materials. The higher this number, the denser the surface it will drill without damaging the mechanism. Also, the power indicator characterizes the time of continuous operation, that is, it determines the speed of work performed. The greater the weight of the hammer drill, the more powerful the motor installed in it.
Rotation speed at idling determines the functionality of the model and application additional accessories. Makita produces a wide range of models with variable speed control. It is set depending on the type of material being processed and the size of the drill. The speed is changed manually by pressing a button or by programmable mode switching.

Over the almost century-long history of its existence, the Japanese company Makita has proven itself well in the world market. Power tools, generators and garden equipment this manufacturer is popular among professionals and amateurs who prioritize reliability, high efficiency and maximum comfort at work.
Many, out of habit developed as a result of the influx of Chinese goods of dubious quality in the 90s of the last century, are still cautiously asking sellers about the country of manufacture of this or that model of Makita power tool and, having heard the word “China”, go home with the hope of finding it the same thing but with the “made in...” label somewhere else. And absolutely in vain. The fact is that today the Makita concern's enterprises are dispersed throughout the world - in Japan, Germany, Romania, Austria, Great Britain, America, Brazil and China. And production is distributed in such a way that certain models are produced only at specific enterprises. This is how production is organized in China today cordless drills and screwdrivers, corner grinding machines, other grinders, individual models reciprocating saws, hammer drills, etc.
For example, it is useless to look for a Makita HR2450 hammer drill made in Germany or the UK for sale. This tool comes only from the assembly lines of one of two Chinese factories, as evidenced by the letters “Y” or “K” at the end of the serial number on the nameplate of the tool itself (the packaging and some components may be from another manufacturer).
The fact that this information is open once again confirms the transparency of Makita's economic policy and responsibility for quality. All new technologies are developed in the brand’s homeland - Japan, and improved at the Okazaki plant, and only after that, under the constant supervision of qualified specialists, they are introduced into production at other enterprises, including Chinese ones.
As for quality standards, they are the same for all Makita products, regardless of the geography of the manufacturer. All factories have certificates confirming the compliance of the existing quality management system with ISO 9000:2000 standards, aimed at satisfying the interests of consumers.
Thus, the quality of Chinese Makita, unless it is a cheap fake, is on the same level as Japanese, English or, for example, German. And to exclude counterfeiting, it is enough to use the services of an official Makita dealer. For example, the services of MakitaPro.
Tools from the Japanese brand Makita are in demand among builders all over the world, thanks to their successful balance of functionality, reliability and reasonable price. The HR2470 rotary hammer is an excellent assistant for home craftsmen, as well as builders and furniture makers who carry out private orders.
Ergonomics comes first
The model with a horizontal engine looks compact, thanks to its small dimensions of 370x84x214 mm. A hammer drill can be easily used to make holes in the most hard to reach places, rubberized main and additional handles provide a secure grip. Fixed to the second depth stop.
Tool capabilities
HR2470 can drill holes without impact in wood (up to 32 mm), metal (up to 13 mm), drill with a blow in concrete blocks, brick (up to 24 mm), hammering walls for expansion doorways, destruction of partitions. At the same time, the bit rotates 360º and can be fixed in 40 positions. The absence of shock at idle significantly extends the life of the tool, and automatic speed control improves drilling accuracy and quality of work.
Protection functions
The safety clutch will prevent the operator from being injured when the tool jams, and will protect the hammer drill itself from damage. The power button can be blocked, if you need to work for a long time without a break, or vice versa, to protect yourself from careless activation of the device.
WITH cord length 2.5 m You won’t have much fun, it will be difficult to get by without an extension cord. But the set conveniently fits into a branded case, which ensures the safety of the instrument during storage and transportation.
The Makita HR2470 rotary hammer is good, first of all, because it is Makita. Compact and reliable tool copes well with light loads. On the other hand, a reasonable question arises: is it worth spending $150 on a generally household hammer drill, if you can buy a similar one, but under a different name, for 30–40% cheaper?

“4+” from me. I don’t let go of the hammer drill.
Makita for a year and a half - I use it as a chipper, screwdriver and mixer. The tool has not undergone any serious repairs; only the brushes had to be changed; at times, grease oozes out of the gearbox. They “took” 24 mm holes in the concrete. It has enough power and “catches up” with its colleagues due to its rotation speed. In general, I advise those who are looking for a reliable and strong perf for reasonable money to get a makita hr2470. sds plus cartridge, reverse and minimal vibration are another tangible plus for your health from Makita.

At one time I used more powerful perfs, like Bosch 2-28. The difference, of course, is felt, but not significant. For its 780 W and 2.7 J of impact force, this “baby” copes adequately with holes in concrete. The main thing is to let the tool cool a little and ensure that the drill is lubricated. In terms of adjustment, the Makita is incomparable, the vibration during chiseling does not torment, and when the drill got stuck in the wall, I mentally thanked the Japanese more than once for reversing it. The price of spare parts compared to Bosch is pleasantly pleasing. In general, a hammer drill is not for jewelry holes – it’s not a drill after all. If you need a tool for serious work, I advise you to buy this hammer drill without hesitation.

I’ve been using this model for 6 years almost every day, doing electrical work. Nice solid car. He endures everything - within reason, of course. It is comfortable to hold in your hands. Vibration during operation is practically not felt. It broke down once - the phase and neutral were connected incorrectly at the facility, and it burned out. There were no problems with spare parts or repairs at all.
