Puncher is an indispensable assistant in dismantling work. With it, you can perform drilling, chasing and destruction of solid structures, applying for this a minimum of physical effort. Although percussion equipment of this type is considered professional, it is often used in domestic settings. Modest in terms of performance, a model of such an apparatus will not be superfluous in the household. How to choose a perforator for an ordinary user? Since the tool is not cheap, the approach must be responsible and comprehensive - taking into account the main performance indicators, functionality, user reviews, etc.
Optimal type of puncher
At the first stage of selection, you should decide on the basic belonging of the instrument to one or another category according to the main classifications. In particular, the design and power supply system should be determined. As for the structural device, there are horizontal and vertical perforators for the home. Which to choose? Models of the first type with a horizontal engine are more like drills. ATin essence, this is an electric drill, but supplemented with an impact function - a kind of jackhammer. This option is easy to handle and a good choice for a beginner, but it is unlikely to be able to perform complex operations for the destruction of concrete and brick structures in a large volume. The vertical configuration is characterized by power and a more efficient cooling system - accordingly, the device will be able to work at high loads.
Now you can go to the power system. Network and battery models are fundamentally separated. As the reviews show, the first ones have a greater power reserve, while maintaining a compact body and lightness. The presence of a battery pack makes the design heavier and reduces maneuverability. Although, the addition of weight in the case of a perforator can also be a plus, since the stabilizing effect increases, which is important during heavy work. How to choose a rotary hammer by type of battery? It is worth focusing on lithium-ion cells (Li-Ion). They do not have the effect of self-discharge, with a small size they have a high energy potential and are undemanding in maintenance. But, one should also take into account the capriciousness of the Li-Ion block when operating at low temperatures and the price factor - compared to other models, rotary hammers with such power supply are 10-15% more expensive.
Selection by technical specifications
The performance range varies depending on the model class. So, the initial level is represented by devices weighing 3-4 kg and with a power of 800 watts. The impact energy in this case is 1-2 J. It turns out a low-power device that is suitable, for example, for electrical wiring, but it is better to entrust serious work with chiselling and deep gating to more productive versions. How to choose a rotary hammer for medium-sized homework? The power potential in this case may also not exceed 1000 W, the main thing is the impact energy. It is desirable to carry out dismantling operations with chiselling with a tool with a force of 3 J or more. This is enough to perform a major overhaul with the creation of large-format holes and openings in the wall. But, as a household drilling machine, such a tool is no longer used.
Manufacturers also produce heavy punching equipment designed for everyday tasks. Models of this class are designed to form 40 mm holes and breaks in stone walls. But in addition to power, it is worth noting the structural reliability and functionality of such rotary hammers. What is the best device to choose from this segment? To perform complex responsible tasks, it is better to purchase models with a power of at least 1200 watts. Accordingly, the impact energy will also be considerable - about 13 J. The influence of high loads on the electrical stuffing is also taken into account. It will be useful to provide for the presence of protective systems and fuses. However, additional options should be considered separately.
How to choose a perforator by functionality?
Continuing the topic of safety and protection of the tool itself, we can highlight the soft start system, overheating protection, fan coolingengine, etc. From the point of view of operability, the possibilities of reverse (reverse) travel and changing the position of the bit will be significant. In particular, Bosch uses its own Vario-Lock mechanism to correct the working equipment. As for the reverse, it can be useful in cases where the drill goes to the side or gets stuck in a rigid array with a rebar grip. But how to choose a rotary hammer if you plan to use different nozzles in addition to large-caliber shanks? It is advisable to give preference to SDS-max or SDS-plus keyless chucks. They not only expand the list of nozzles available for use, but also facilitate the process of changing them without connecting an additional tool.
Point operations under heavy load will also require electronic speed control. This function is useful if you plan to work with materials of different degrees of density. The most modern versions automatically adjust to the working basis by assessing the pressure on the drill and the degree of pressing the start button. Another question is no less important - how to choose a hammer drill for homework, taking into account auxiliary functional accessories? In this part, it is worth providing for the laser guidance of the drilling point, LED illumination and a safety clutch. All this contributes to high-quality drilling with precise centering of the working body. For greater reliability, an anti-vibration system should also be provided, which reduces the effect of vibrations on the accuracy of the orientation of the drill.
Model Makita BHR242RFE
A device with an unusual configuration of power filling, which combines a balanced design and high power with a low impact force of 2 J. Users consider it the borderline version of an impact drill between professional and household segments. That is, if there is a question about how to choose a good universal-purpose puncher, then you can refer to this particular proposal. The operational feature is that the power filling is focused on performing short operations, but with high peak power. In comparison, full-fledged professional models are designed to withstand high loads over long work sessions.
Also, this model represents the battery class. The lithium-ion unit has a small energy reserve of 3 mAh, but this is enough for the same household repair activities. An additional battery is included in the kit. Here it is important to reveal some of the nuances of the non-stop operation of rotary hammers for the home. Which device to choose in terms of autonomy? It is desirable that a balance be struck between capacity, charging time and the duration of the workflow. It is this advantage that distinguishes the BHR242RFE modification. While the energy of one block is replenished, the master can work with the second for several hours. As for other advantages, the model is also equipped with vibration protection, dust isolation and thoughtful body ergonomics, which traditionally distinguish Makita power tools.
Bosch Model GBH 18
This unit is colored blue, indicating that itbelonging to a professional group according to the corporate classification of a German manufacturer. However, the cost of 14 thousand rubles. allows many home users to acquire such an assistant. Moreover, in terms of ergonomics and optimization, this is one of the best rock drills with a lightweight design. Yes, the performance is low - only 1.7 J at 18 V. Also, the processing parameters are not impressive - for concrete, the drilling diameter is a maximum of 20 mm. But these modest indicators for domestic use are not a critical limitation, but in return the owner receives a small, light (2.3 kg) and maneuverable body, as well as a high spindle speed, which allows you to work with small drills. Quite often, professional builders are faced with the question of how to choose the right hammer drill in order to get both a balanced design and not lose power. Of course, the performance in this case is unimportant, but the convenience of physical handling is at the highest level. As the users themselves note, you can even work with the GBH 18 puncher with one hand.
Model "Interskol" PA-10/14, 4Р-2
A solid domestic rotary hammer, made on a battery basis with the basic functionality of an impact drill. The robust body of the tool provides protection from physical damage, the mode switch is responsible for setting, and the shanks are fixed with a quick-release chuck. By the way, the SDS-plus retainer accepts drills with diameters of 5, 6 and 8 mm. Also forwork in hard-to-reach places, the developers have provided a backlight. What is also important in this model is the operational versatility with a wide coverage of work operations - this is also confirmed by reviews of the rotary hammer. Which tool to choose for performing both impact drilling and screwing hardware? This is a popular question of ordinary home masters who do not need specialized functions, and the "omnivorous" device comes to the fore. And the creators of the model in question just offer the performance of various tasks at an average power potential. As a result, concrete with metal can be processed with a diameter of 10 mm, and wood - up to 20 mm. And within the framework of the same production process, without changing the tool, the operator will be able to be distracted without a hitch and tightening the screws.
DeWALT D25144K
This time it's all about high performance, as evidenced by the 3.2J impact mechanism backed by a 900-watt motor. The perforator also works successfully in shockless mode, which can be switched to after replacing the standard SDS-plus chuck with a conventional three-jaw grip. In other words, this is the same universal design that is suitable for working in screwdriver mode. But, small-format fast operations with constant movements around the site are not the best format for using this version. Yet the design of a powerful impact drill is designed for more solid tasks. And how to choose a rotary hammer for repair, so that it combines compactness, lightness, versatility andperformance? On the one hand, this is a contradictory combination of characteristics, and on the other hand, the rejection of the battery pack while maintaining the usual network drive, at least guarantees not to exceed the weight at average power. It is in this configuration that the D25144K modification is proposed, but, as users note, you will have to pay for ergonomic advantages with strong vibrations and noisy operation.
Model AEG PN 11 E
It should be noted right away that this hammer drill belongs to the highest class and is estimated at 45-50 thousand rubles. What does the owner of this unit get? 1700 W motor, 27 J impact energy and 11 kg of weight. That is, the model has practically no restrictions in terms of application - at least within the framework of tasks that, in principle, are available for a perforator as such. At the same time, the owners emphasize not so much versatility with a wide range of operations under their control, but ease in solving quite standard repair tasks.
Of course, for such a price you can count on the presence of innovative systems. Gearbox carbon brush wear indicator, idle speed limiter and soft start are just some of the useful options that are positively noted in the reviews. Which hammer drill to choose for the home so that it combines reliability, endurance and ease of manipulation is also a common question asked by amateur craftsmen who understand these qualities. It cannot be said that the AEG PN 11 E demonstrates record performance and can compete withsmall-sized counterparts in terms of ergonomics, but the developers still felt a certain balance. Despite the weight of 11 kg, the model effectively copes with drilling tasks without a lot of stress on the hands - this is facilitated by the thoughtful design of the body and the high speed of the operation.
Rating of the best models
Each of the above models has its own advantages in different aspects of application. Their combination, taking into account the cost, will answer the question of how to choose a hammer drill for homework. The rating below focuses on the most popular and high-quality models available on the market for ordinary users:
- Bosch GBH 18. The main quality of this device is balance. It concerns both the immediate working qualities and the price tag. The model is a little beyond the cost range of a strictly domestic class, but a modest overpayment for high German quality is fully justified.
- Makita BHR242RFE. The Japanese brand is a direct competitor to Bosch, but the class of this model is higher than the previous offer. The difference in price is 10 thousand rubles, and this, even taking into account higher operational data, is not suitable for every amateur master.
- "Interskol" PA-10/14, 4Р-2. On the contrary, a budget option that is in good demand. But, this rotary hammer still cannot compete with Makita products in terms of reliability and durability of the element base.
- AEG PN 11 E. For a unique combination of performance and an abundance of modern features with increasedperformance, this device also deserves a place in this rating, but given the price tag, it is far from the first position.
- DeWALT D25144K. In general, a good model that can compete with each of the analogues below on individual qualities, but the imbalance between ergonomics and power makes it a specific proposal designed for a narrow segment.
When evaluating these options, consider your workflow requirements. In some cases, performance will come to the fore, in others - reliability, and in others - functionality. Perhaps, as a compromise solution, it is worth choosing a Makita puncher worth 24-25 thousand rubles. That's a lot of money for home appliances, but you can be sure that all hammer drilling tasks will be completed without unnecessary worries.
Conclusion
Puncher is certainly a useful and in some way indispensable tool. However, the average homeowner needs it only on rare occasions. More often, a standard electric drill is used, which is cheaper, more manageable and lighter. How to choose a perforator for apartment renovation in order to cover as many tasks as possible? You can go in a slightly different way. The main difference between the perforator is the presence of the function of the percussion mechanism. But today it is also provided for some drill models. For example, battery versions with a voltage of about 24 V may well replace a corded puncher. For the right choice, you only need to calculate the specific technical parameters andsuperimpose them on the processing capabilities of target surfaces and building materials.
