Manufacturers of angle grinders increasingly combine high power and ergonomic advantages in their products. If before the power potential was important rather for professional models, today even small household tools are endowed with decent performance. Another thing is that in a household the excessive power of a grinder, as a rule, is not needed. As for ergonomics, this is the main characteristic that should be considered when choosing this unit for domestic use. The Japanese HITACHI G13SS grinder shows an example of the optimal combination of professional qualities and ease of use. Of course, similar developments can be found in the lines of other manufacturers, including Bosch and Makita, but HITACHI specializes in professional tools, therefore the main bias is made in this direction.
Model description
Externally, the device is a typical grinder, in which there is not a hint of high performance. The model has compact dimensions, comfortable handles and a generally presentable look. It is difficult to find flaws, backlashes or shifts in the formation of the structure by individual elements on the case - the manufacturer takes a responsible approach to the assembly process, so reliability should immediately be put in plus with the HITACHI G13SS. The price of the instrument in the domestic market varies from 2 to 3 thousand rubles. For a small grinder, this is a lot, but do not forget about the internal filling, thanks to which the model is positioned as a professional. True, the range of tasks subject to this apparatus is not so wide. As the manufacturer himself notes, the machine can be used for processing castings from aluminum and bronze, as well as for grinding welds and areas where gas cutting was carried out. By the way, this power tool also copes well with cutting metal billets.
Specifications
The model has good features for convenient and quick processing. This is facilitated by both performance and the convenient design of the HITACHI G13SS modification, the technical characteristics of which look like this:
- Type of tool - angle grinder.
- Weight - 1.4 kg.
- The output power is 580 watts.
- Disk diameter - maximum size 12.5 cm.
- Peak speed is 10,000 rpm.
- Spindle - M14.
- The size of the landing hole is 2.2 cm.
- Food - network.
- Additional features - start button lock, spindle mount, the presence of a second handle.
When compared with competitors in the class, rather modest power indicators are noted, which should also affect the low processing efficiency. Indeed, according to this indicator, the model is not the leader of the segment. But this drawback of the HITACHI G13SS is compensated by the high speed. Actually, in combination with a convenient design and a large disk, this device provides decent performance.
The advantages of a grinder
This tool does not indulge in new technological options, unlike the competitors Makita and Bosch. But there are several structural solutions that provide serious benefits in the eyes of the consumer. So, first of all, this refers to the lightweight body, which allows you to work on weight and even with the lifting of the device above your head. The compactness of the HITACHI G13SS machine also allows it to be used in hard-to-reach areas. Another advantage of the model is a competent addition to the design of the second handle. This solution, of course, is not new, but Japanese designers removed the restrictions on the choice of its location. The handle can be fixed both on the right and on the left - depending on the requirements of the workplace. In addition, for a quick change of parts, the creators provided free access to the brushes, which allows you to conduct the work process continuously.
The nuances of operating the grinder
The manufacturer recommends not to abuse with pressing the tool during surface treatment. As a rule, the mass of grinders is sufficient for optimal pressure on the working area. It is also recommended to apply the grinding wheel not at the entire surface, but at an angle - this position provides optimal processing parameters and increases safety. After changing the wheel in the HITACHI G13SS, it is recommended to continue working with the product so that the tool is located across the previous line. As the abrasion of the working edge of the grinding wheel, you can use different positions during processing.
Tool maintenance
First of all, you should check the integrity of the working circle - this is especially true for elements with a recessed center. Next, all screws must be tightened to ensure the tightness of the housing and the reliability of the fastening of its components. Carbon brushes are used in the construction of the tool, the malfunctions of which can lead to engine damage. In order for the HITACHI G13SS angle grinder to last as long as possible, it is recommended to check the condition of the brush holder in a timely manner. These elements have their own working resource, therefore, it will not be difficult to calculate the approximate replacement time. As for the engine, in addition to visual inspection, it is necessary to monitor the regular change and quality of its oil.
Positive reviews
Almost all owners note the ease of handling the machine. Sophisticated design with an additional handle greatly simplifies the workflow for both professional builders and inexperienced home craftsmen. In particular, the light weight and compactness of the HITACHI G13SS are noted. Reviews also emphasize the advantages in the form of mobility, which makes it possible to work in any position. In terms of performance, there are also many good opinions, but for severe operating conditions this option is still not recommended.
Negative reviews
Despite successfully implemented ergonomics, the model looks old-fashioned. Of course, this factor is not fundamental in choosing a construction tool, but many consumers make up an opinion on a product in appearance. Unfortunately, in the case of the Japanese grinder, this approach justifies itself. The typical design of the instrument is in harmony with its filling, which is not deprived of modern functions. True, many users still pay tribute to the high quality of the HITACHI G13SS element base. The price of 2-3 thousand rubles, according to many owners, is too high. In a budget class with similar characteristics, you can also find devices within 1 thousand rubles. Another thing is that these will be little-known brands whose product quality is in doubt.
Conclusion
For the Japanese manufacturer, the initial segment is not the main field for the realization of their capabilities. The company embodies all the most significant modern developments in models of the middle and highest price level. Nevertheless, the Bulgarian HITACHI G13SS still received a number of proprietary properties. This applies to a well-thought-out design, and to the reliability of parts, as well as to a good combination of tool sizes and its power. In practice, the use of this machine rather provides advantages in the form of ease of manipulation. But this does not mean that the quality of processing is fading into the background. The model can be equipped with circles with a diameter of 12.5 cm, which significantly expands the range of operations.
