Repair activities often involve combined installation tasks. For such cases, a multifunctional tool, which includes a puncher, is excellent. With it, you can perform both drilling and chiselling walls with destruction, but at a price this is not the most affordable solution for an ordinary home craftsman. Nevertheless, the Dew alt D25133K rotary hammer, which is part of the middle price segment, is optimal for such an audience. This model at a low cost offers a wide range of functions and surpasses the quality of budget Chinese competitors.
General information about the tool
Moderate rock drill with the necessary options for basic demolition operations. The drilling function can be applied to concrete, brick and stone withthe possibility of installing anchor fasteners. In terms of functionality, the device corresponds to the current level of development of this technology, providing the user with the ability to change the frequency of the spindle and electronic speed control. The bit, and in particular the bit, can be placed in any suitable position by operating the pivoting mechanism. In addition, the Dew alt D25133K rotary hammer is provided with anti-vibration protection and an auxiliary multi-position handle, which also improves the ergonomics of the design. 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 in the emitted dust, purifying the air environment in the working area.
Specifications
The machine is part of the general family of premium power tools, although the lower price tag has not allowed it to fully provide a high degree of performance. This is evidenced by the moderate characteristics of the Dew alt D25133K rotary hammer, presented below:
- Power - 800 W.
- Diameter of holes when using a crown - up to 50 mm.
- Diameter of drilling with a drill - up to 26 mm.
- Diameter of wood drilling - up to 30 mm.
- Drilling diameter of metal materials - up to 13 mm.
- Impact force - 2.9 J.
- Frequency of impact torque - up to 5500 bpm.
- Speed - range from 0 to 1500 rpm.
- Dimensional design parameters - 335x210x75 mm.
- The weight of the device is 2.6 kg.
Relatively low power compared to the power potential of high-end impact electric drills determines that the tool belongs to the household segment, which is quite justified. What's more, the Dew alt D25133K-KS version of the rotary hammer has a slightly reduced impact load, with an emphasis on light, typical home drilling and chiselling tasks.
Operating instructions
Before starting work, it is necessary to accurately determine the place of application of the tool, making sure that there are no communications (pipes, electrical wiring, cables, etc.) at the heart of the structure. The rotary hammer is provided with a suitable attachment through the SDS-Plus chuck, after which the desired operating mode is selected - drilling, drilling with impact force or chiselling. In the process of performing any operation, it is necessary to firmly hold the Dew alt D25133K perforator with only two hands. A photo with an example of tool capture is presented below. It is important to direct the working head strictly to the point of mechanical action without deviations and excessive pressure. The power load exerted on the device by the user must be within 5 kg. Excessive pressure will not improve drilling performance or structural failure, but may damage the bit and damage the tool's motor. Turn off the hammer after the operation is completed only in the free position, when the drill orthe crown has been pulled out of the working surface.
Maintenance instructions
Because the nature of the use of impact drills is associated with dusty work, you should clean the structure 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, as they accumulate the largest amount of dust. External surfaces can be cleaned with a damp cloth or napkins, but, as the instructions for the Dew alt D25133K perforator note, without the use of solvents and other aggressive chemicals. These and other maintenance activities should be performed only with the equipment turned off. By the way, if the tool starts to turn itself off regularly, this may indicate the need to replace the carbon brushes for the engine. The design provides a special indicator that acts in this way when fixing the critical wear of this consumable.
Work Safety
During the operation of this rotary hammer, the following safety precautions must be observed:
- The workplace should be free and well lit.
- Do not use the tool in places where flammable materials or containers with gas mixtures are located.
- You can only connect the Dew alt D25133K rotary hammer to a compatible socket (220 V) without the use of connecting adapters.
- Directly in the course of workdirect contact with grounded objects and surfaces should be avoided.
- The use of a puncher outdoors in conditions of precipitation or in rooms with high humidity in the air is also excluded.
- Personal safety should also be taken responsibly, using personal protective equipment in the form of goggles, a respirator and special shoes with anti-slip soles.
Positive feedback about the model
Reducing 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 in the first place in the list of advantages of the model. The device is quite light, compact and maneuverable, which allows you to use it almost like a regular drill in the most secluded places. These advantages are especially emphasized in reviews of the Dew alt D25133K-KS rotary hammer with optimized technical stuffing. The performance degradation in home wiring is not as significant, and the comfort and ease of handling power equipment is highly valued. Many users add to this a we alth of functions - both in terms of the choice of operating modes, and in relation to settings with adjustments.
Negative feedback about the model
There is criticism regarding the lack of endurance and power output of the tool, but given its class and purpose, such comments are not defining the quality of the technique. At the same time, there are quite reasonable negative reviews about the Dew alt D25133K puncher, whichrefer to specific workflow flaws in some modes. In particular, claims highlight the instability of the behavior of nozzles - 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 unfortunate location of the side latch relative to the switch. Jamming may occur accidentally when changing the position of the hands or the position of the master.
Conclusion
Dew alt's offer, with some stretch, enters the niche of rotary hammers in their classical sense as powerful power equipment 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 an affordable price tag. Even in this category, the Dew alt D25133K rotary hammer has many strengths that allow it to outperform analogues from Makita and Bosch in some respects. And yet, 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 amateur users. At the same time, the existing functionality base makes it possible to use the D25133K device in the professional field, but for simple tasks.
