In repair activities, it is often necessary to perform combined tasks related to installation. For such cases, a multifunctional tool, to which a rotary hammer belongs, is excellent. With its help, you can perform drilling and chiselling walls with destruction, but at a price this is not the most affordable solution for an ordinary home master. Nevertheless, such an audience is best suited for the Dewalt D25133K rotary hammer, which is included in the middle price segment. This model at a low cost offers a wide range of functions and is superior in quality to budget Chinese competitors.
Tool Overview
A model of a hammer drill with moderate power and the necessary option to perform basic dismantling operations. The drilling function can be applied to concrete, brick and stone with the possibility of installing anchor fasteners. In terms of functionality, the device meets the current level of development of this technique, providing the user with the ability to change the frequency of the spindle and electronic speed control. The nozzle and, in particular, the bit can be installed in any suitable position, using the function of the rotary mechanism. In addition, the Dewalt D25133K rotary hammer is provided with anti-vibration protection and an auxiliary multi-position handle, which also increases the ergonomics of the structure. To reduce the amount of dirt during operation, the tool device also provides the option of connecting an air duct from a construction vacuum cleaner. Directly during dismantling or drilling, a special nozzle sucks the exhaust dust, cleaning the air in the working area.
Specifications
The device is part of the general family of premium power tools, although the reduction in the price tag did not allow it to fully provide a high degree of performance. This is also evidenced by the moderate characteristics of the Dewalt D25133K punch, presented below:
- Power - 800 watts.
- The diameter of the holes when using the crown is up to 50 mm.
- The diameter of drilling with a drill is up to 26 mm.
- The diameter of wood drilling is up to 30 mm.
- Diameter of drilling of metal materials - up to 13 mm.
- Impact force - 2.9 J.
- The frequency of the impact moment is up to 5500 bpm.
- Rotational speed - a range from 0 to 1500 rpm.
- Dimensional design parameters - 335x210x75 mm.
- The weight of the device is 2.6 kg.
Relatively small power in comparison with the power potential of high-class impact electric drills causes the tool to belong to the household segment, which is quite justified. Moreover, the modification of the Dewalt D25133K-KS rotary hammer has a slightly reduced shock load with an emphasis on the implementation of simple typical drilling and chiselling tasks at home.
User's manual
Before starting work operations, it is necessary to precisely determine the place of application of the tool, making sure that the communications do not pass at the base of the structure (pipes, wiring, cables, etc.). The hammer drill is provided with a suitable nozzle through the SDS-Plus cartridge, after which the desired operating mode is selected - drilling, drilling with impact force or chiselling. During any operation, hold the Dewalt D25133K rotary hammer firmly and only with two hands. A photo with an example of a tool capture is presented below. It is important to direct the working head strictly to the point of mechanical impact without deviations and excessive pressure. The power load exerted on the device by the user should be within 5 kg. Excessive pressure will not increase the efficiency of drilling or structural failure, but may lead to damage to the nozzle and damage to the tool engine. Turn off the hammer after the operation is completed only in the free position, when the drill or crown is pulled out of the work surface.
Maintenance Instructions
Since the nature of the use of impact electric drills is associated with dusty work, the structure should be cleaned regularly. All foreign particles and dirt are blown out only with dry air under pressure. Particular attention is paid to the ventilation openings of the case, since the largest amount of dust accumulates on them. Exterior surfaces can be cleaned with a damp cloth or napkins, but, as noted by the instructions for the Dewalt D25133K punch, without the use of solvents or other aggressive chemicals. These and other maintenance activities should only be carried out with the equipment turned off. By the way, if the tool starts to regularly turn itself off, this may indicate the need to replace carbon brushes for the engine. A special indicator is provided in the design, which acts in this way when fixing the critical wear of a given consumable.
Work Safety
During operation of this rotary hammer, the following safety requirements must be observed:
- The workplace should be free and well lit.
- In places where there are flammable materials or containers with gas mixtures, do not use the tool.
- You can only connect the Dewalt D25133K rotary hammer to a compatible outlet (220 V) without the use of connecting adapters.
- Direct contact with grounded objects and surfaces should be avoided during operation.
- The use of a rotary hammer outdoors in the event of precipitation or in rooms with high humidity in the air is also excluded.
- It should be responsive to personal safety issues, using personal protective equipment in the form of glasses, a respirator and special shoes with anti-slip soles.
Positive feedback about the model
The reduction in power could not but give a lot of advantages in terms of ergonomics of use. It is the convenience of physical handling that many owners put on the first place in the list of advantages of the model. The device is quite lightweight, compact and maneuverable, which allows you to use it almost like an ordinary drill in the most secluded places. Especially these advantages are emphasized in reviews of the Dewalt D25133K-KS puncher with optimized technical stuffing. The decrease in performance when performing home installation is not so significant, and comfort and ease when handling power equipment are highly valued. Many users add to this the richness of functions - both in terms of choosing operating modes, and in relation to settings with adjustments.
Negative model reviews
There is criticism regarding the lack of endurance and power recoil of the tool, but given its class and purpose, such comments are not determining the quality of the technique. At the same time, there are also quite reasonable negative reviews about the Dewalt D25133K rotary hammer, which relate to specific flaws in the workflow in some modes. In particular, the claims highlight the instability of the nozzle behavior - the drill can "walk" and deviate from the axis due to the beating of the cartridge. There is also a “wedge” of the trigger in the pressed position, which experts explain by the unsuccessful location of the side lock relative to the switch. Jamming may occur by accident when changing the position of the hands or the position of the master.
Conclusion
The offer from Dewalt with some stretch enters the niche of perforators in the classic sense of them as a powerful power technique for dismantling. But on the other hand, this class is in demand on the market precisely because of the balance of technical and operational qualities with an emphasis on domestic use and a democratic price tag. Even in this category, the Dewalt D25133K puncher has many strengths that allow it to win in competition with its counterparts from Makita and Bosch in some respects. Nevertheless, certain design errors and the general weakness of the power plant impose restrictions on the use of this model, which should be borne in mind by users of the amateur level. At the same time, the existing base of functionality makes it possible to use the D25133K in the professional field, but for simple tasks.
