How to choose a hammer drill for personal use? Nowadays, buying a branded drilling tool is not a problem, but how to choose the right hammer drill for yourself and your tasks? Explore the punch device and specifications.
Energy and frequency of impacts
For a hammer drill, the impact function, measured in joules, is very important. The performance of the device, as well as the diameter of the hole to be machined, depends on the impact energy. For daily work with a hammer drill, this is one of the most important indicators.
It is essential that the hammer drill at the maximum will very quickly deplete its resource, and with the hammer drill they perform this work for a long time without wear, especially with the single-mode model.
It turns out that energy and frequency determine the level of performance. When choosing a perforator on your own, you need to evaluate the amount of work on chiselling, then, according to the specified characteristics of the impact frequency, calculate the approximate productivity.
What is the difference between a drill and a hammer drill and vice versa
The hammer drill is characterized by a longitudinal axial movement of the working part, similar to an impact drill. Therefore, hammer drills are confused with a heavy drill. In words, there is practically no difference, however, the hammer drill functions on the basis of pneumatics, and any impact (heavy) drill works thanks to mechanics.
Hence the difference in surface speed. Pneumatic drilling of holes in concrete, brick and stone walls reduces physical stress on the user. For any hammer drill, similar work is associated with great fatigue, and the hammer drilling mode wears out the internal components of the drill very quickly.
We come to the conclusion that the hammer drill should be larger and more massive than a drill with an impact function.
Punch device and characteristics
All punchers are divided into three types in terms of functionality:
- Single-mode. Impact drilling function only. Most often, such perforators are not used in everyday life, but are used as professional additional equipment for narrow purposes.
- Dual mode. Hammer drilling plus classic drilling or chiseling only.
- Three-mode. The tool is equipped with all the functions specified in paragraphs 1 and 2.
The choice of a hammer drill is based primarily on the characteristics of power and impact force. The higher these indicators, the better the hammer to be fitted.
Types of working chuck for rock drill:
- Usual;
- Quick-clamping.
Which drill chuck to choose? For household or household chores, the keyless quick-release model is best suited. Changing the nozzle in this version is convenient, easy and quick.
Rock drill classification by weight:
- Lungs. Up to 4 kilograms. Power is no more than 700 watts. Only available with SDS-plus chuck for 26 mm drill bits.
- Average. 4 to 8 kilograms. Power from 700 to 1500 watts. Depending on the equipment, both SDS-plus and SDS-max are equipped.
- Heavy. than 8 kilograms. Power is over 1500 watts. Equipped only with SDS-max chuck for diameter up to 60 mm.
Rotary hammer from Bosch or Makita?
Bosch GBH 2-26 DRE is the most popular model from the German company, perfect for a wide variety of construction work. Lightweight, handy and compact, with a rubberized body and handle, this rock drill is suitable for many works related to slitting and wall drilling.
The engine of this model is placed horizontally, which in turn allows it to be conveniently used in various positions and in the most inaccessible places. In terms of its characteristics and operational capabilities, this model of Bosch rotary hammer strongly resembles the Makita HR2450.
The technical features of this rock drill are as follows:
- Weight approximately 2.7 kg;
- Availability, three modes of operation: conventional drilling without striking, drilling walls and percussion mode for chipping;
- The presence of an electronic speed controller;
- The presence of a safety clutch;
- Drilling diameter up to 26 mm;
- Reverse turns.
Of the features of this model of Bosch punch, it should be noted the presence of a rotary brush holder and a power cable fixed on a special swivel hinge, which prevents it from breaking when working with the punch.
Rotary hammer from Bosch or Makita?
Rotary hammer from Bosch or Makita?
In fact, it is difficult to give an advantage to any particular rotary hammer from these two companies, since the quality and reliability of the tool, both of the one and the other, are always at their best. You can view various models of perforators from Bosch, for example, on the website http://abo.Ua/perforatory/bosch/ where a large selection of them is presented.
Those who have worked with hammer drills from both Bosch and Makita know that both of them are great for professional repair and construction work. Therefore, in order to still make a choice in favor of some one company, one should first of all build on the functionality of the selected perforator and its design features.
Below we will consider such popular hammer drills today as Bosch GBH 2-26 DRE and Makita HR2450. There will also be a short comparison for both models.
Rotary hammer from Makita model HR2450
Now it is necessary to understand in more detail exactly what technical features the hammer drill from Makita HR2450 possesses and whether it is worth giving preference to it.
The fact that this model of a perforator from a Japanese company is popular is not enough to say, because this tool has been produced for more than ten years. The optimal combination of technical characteristics, ease of use and a completely affordable price, made this model of the hammer drill from Makita quite competitive with the above model from Bosch.
From its technical characteristics it can be noted:
- Light weight, about 2.4 kg;
- Availability of 3 modes (drilling, drilling, fighting);
- Availability of a release clutch and electronic speed control;
- Drilling diameter (slightly smaller than Bosch) 24 mm;
- Possibility to set the bit in any position.
Given the features of these two popular models of rock drills today, we can safely say that both models have excellent operational capabilities. Both of these rotary hammers are easy to use, suitable for use in everyday life and for various professional work.
Makita brand. Real japanese build
Makita is a Japanese brand that specializes in the production of gasoline and electric tools for the home and professional use. The company was founded in 1915. At the beginning of its activity, the creators of the brand specialized exclusively in the repair and sale of lighting equipment. For the first time its own products under the Makita brand entered the market in the twenties of the last century.
A little about Bosch
Bosch is a German company. The firm was founded in 1886. Rotary hammers from this manufacturer occupy one of the most important places in the professional power tool market. The company specializes in creating tools for both small household repairs, where the models come mainly with the SDS-Plus chuck, and for work on large construction sites, where the company presents a wide range of tools with models with all popular SDS-Plus, SDS- Max, SDS-TOP HEX.
Why are Bosch tools so good? This is really proven German quality over the years, and on most models you can find the inscription Made in Germany, beloved by everyone. But since today the company is so wide and has over 200 of its own factories around the world, the equipment can be produced in other countries, for example, the household line (green) can be assembled in Hungary, China and Russia.
Bosch and Makita rotary hammers warranty
The number of service centers that serve both brands is also sufficient throughout the country, so there are no special problems with fast and high-quality repairs.
And some information about the cost of spare parts. Makita in this regard is partly cheaper, since original spare parts for the tool are produced at a factory in China.
Brand overview
Bosch
Bosch (or rather, Robert Bosch GmbH) is a group of German companies that specializes in the production of high-tech equipment in various fields. The company was founded in 1886 and initially focused on electrical engineering and precision mechanics. Not surprisingly, starting in the 1890s (the start of electrification in Germany), Bosch’s business began to develop rapidly, occupying new market niches, including those related to the design and manufacture of power tools.
The presence of its own engineering department in the company has served well in the expansion in the market of household and professional tools. It was under the Bosch brand that such devices as a jigsaw, a rotary hammer, a variable grinder, a cordless rotary hammer, etc. Were first released. This also includes the SDS-Plus perforating drill attachment system, it was developed and first introduced by German engineers.
In general, Bosch power tools fully comply with our ideas about German quality standards, they are reliable and durable, therefore the purchase should be considered as a fairly long-term investment.
Makita
Makita Corporation (Japan) was founded somewhat later in 1915, and initially focused on the manufacture of generators and electric motors. In 1958, the first line for the production of power tools was launched: the first electric planer was released under the Makita brand, which at that time had no analogues.
Today the company produces more than 1000 brands of tools of 350 different types. Technological capacities are partially moved outside Japan and are located in Great Britain, Romania and Germany.
Comparison by key parameters
Professional and household lines
For a correct comparison between Bosch and Makita, it is worthwhile to figure out which lines of tools these corporations produce.
- Blue series professional equipment. Actually, this is the very Bosch, which is characterized by high power, long service life and safety margin.
- Green series power tools for household use. Due to limitations in power and functionality, as well as the use of less durable materials, the manufacturer seriously reduces the cost of products. But their safety margin also suffers, in any case, in comparison with the professional line.
Sometimes models are released in the green series, which they then plan to bring to the professional market. Therefore, the household segment often serves as a testing ground for new products.
- It produces only professional tools under its own brand, so it should be compared only with the blue Bosch series. The performance parameters of the products are at the highest level, so that there are almost no significant claims from the craftsmen.
- In the 90s, Makita Corporation attempted to launch a line of household power tools under the Maktec brand. The products turned out to be cheaper, but they were significantly inferior to their professional counterparts in terms of power and reliability.
Cost and other factors
- Power. In principle, it is equivalent for both brands (at the same level of energy consumption). In rare cases, Bosch outperforms the Makita in certain parameters (for example, efficiency on concrete).
- Ergonomics. The Makita is in a better position here, primarily because of the lighter tool mass. With long-term work, this plus becomes quite significant.
- Resource. Bosch with its German quality is noticeably better. Despite the fact that Makita has good control over production in different countries, the overall level of reliability of the tools is still somewhat lower.
- Functionality. This parameter can be assessed in two ways: Bosch is the first to have new functions, Makita brings them to mind perfectly, but with a significant time delay.
- Prices. Bosch costs a little more on average (if we talk about tools of a comparable class). On the other hand, the difference is usually not so significant, and it can be compensated by finding a retail outlet with a more democratic pricing policy.
Which is better: Bosch or Makita?
In any environment, professionals often get into arguments about which brand is better. For photographers, this is, of course, the eternal confrontation between Nikon and Canon, for owners of Apple smartphones with its iOS and Samsung with Android, etc.
Builders and finishers also do not stand aside, and quite often they discuss the advantages and disadvantages of certain brands of tools. But if you compare, then compare the best representatives, therefore we turn to the results of the survey on the site. As of May 2017, in a survey of their preferred brand of construction tools, 31% of users voted for Makita and 23% for Bosch. So we will choose the leader from these two brands and try to decide which is better than Bosch or Makita.
Angle grinder Bosch or Makita, which is better?
Moving on to the next pair, this time let’s compare the Bosch GWS 850CE and the Makita GA5030.
Bosch GWS 850CE
Disc size (max, mm)
In this comparison, the GWS 850CE looks like a clear leader due to the higher power, but there are many complaints about it. In particular, on a switch that is too hard, as well as on the factory lubrication of the gearbox. The latter applies only to the Russian assembly. In addition, professionals blame the lack of a complete set of this model.
Relative to the Makita GA5030 model, it has a clear advantage of its low weight, which is explained by the small size of the tool. Thanks to this, the hands do not get so much tired. Otherwise, these angle grinders are almost identical in performance and functionality. Therefore, choosing only between them, it is difficult to point out the unequivocal advantage of this or that model. However, if we take the approach, then the choice again tends in favor of Makita, due to the primacy of simplicity and convenience over purely technical characteristics.
Features of the Bosch brand:
Germany. The assembly is usually Malaysian;
Basically three years warranty (one year in Makits);
Better performance characteristics and, as a consequence, more weight.
Rotary hammer Bosch or Makita, which is better?
In this market segment, you can compare the BOSCH 2-24D and Makita HR2470 models.
Maximum drilling diameter (mm)
Rotation speed (max rpm)
As you can see from the table, the difference between the models is very small. However, for the sake of fairness, it should be noted that the chiseling function is better developed in BOSCH 2-24D. In contrast, we can say that the Makita HR2470 is equipped with special carbon readouts that increase the service life, and this model is also lighter and faster. What is more important for professional use, since it is important during long-term work and will save money in the future. Hence, in this example between bosch or makita, the last brand wins.
