Choose the best heavy punch - top review 11 SDS MAX - Makita( Makita), DeWALT, HITACHI, Hilti, AEG

How to choose a heavy, convenient, but not large puncher with SDS MAX cartridge( SDS MAX)?It would seem that in Europe the crisis reigns, the stagnation of production, buyers tempered the ardor. However, most manufacturers with loud names continue to increase their turnover and produce large-sized tools. Particular attention is paid to such companies by jackhammers and electric punchers as one of the most popular on the construction market. We have already told you how to choose a puncher for your home. T Now we select the heavy puncher SDS MAX of the following manufacturers - Makita( Makita), DeWALT, HITACHI( Hitachi), Hilti, AEG.

It is significant that the giant of production of construction materials with many years of experience - the company METABO - only recently approved the production of heavy shock equipment as a clearly promising area. Do not fall behind and the company DeWalt, widely known for the production of woodworking tools of high quality, offering customers perforators and jackhammers. High level of profitability from the sale of shock equipment is achieved, first of all, by rather expensive service, and not by extra charges. Due to the tremendous load level that the tools, parts and mechanisms carry, wear out quite quickly, requiring replacement and reconstruction.

Features of the design of heavy punchers and jackhammers

The choice of fastening systems in percussion instruments, in particular, chisels and drills, has long been removed. To date, almost all manufacturers have opted for the SDS MAX system due to the exceptional wear resistance of parts, resistance to overloads, as well as to the destructive effect of vibration. This unanimity in the ranks of manufacturers has found a positive response among consumers as well.there is an opportunity to choose consumables, focusing not only on specific manufacturers, but also within the desired price category.

At the same time, as you know, the miser pays twice, and the consumer, wanting to save, often forgets that hammers and punchers, whose energy of impact is extremely high, can not be equipped with cheap consumables. Take as an example two punchers with the impact force of 12 J and 27 J( DWT BH-1500 BMC with a power of 1500 W and AEG PN 11 with a power of 1700 W respectively).In both cases, the impact energy during the operation of the tool is sufficient to flatten the shank of a drill of poor quality and low price without the possibility of self-recovery. However, the builders are fully entitled to pay for the replacement of the barrel of the percussion instrument, which will fly into a pretty penny. Let's count: the item costs several hundred dollars, the cost of restoring the perforator itself and replacing the part is also not in tens of rubles calculated. The amount of overpayment is easy to calculate.

As you know, the requirements for European manufacturers of percussion instruments are several times higher than the requirements in our country. Our goods simply do not pass strict quality control when exported abroad: there are electrical interferences that affect the quality of the work, high noise level and unacceptable level of vibration - unfortunately, the framework that has long become the norm for manufacturers from Europe, for our manufacturers are a kind ofProcrustean bed. There is no way to squeeze into it yet. In particular, foreign-made equipment is now equipped with anti-vibration handles and anti-cushioning pads that significantly reduce damage to builders during operation.

Makita - a well-established company in the field of production of percussion instruments - for quite a long time produced a perforator model HR5001C SDS-MAX without significant changes in the design, which, incidentally, were not necessary. The perforator fully complied with the requirements of that time: high endurance, wear resistance and efficiency, coupled with engine power of 1500 W, impact force of good 17, 5 J, weight 10 kg and cost slightly less than 20 thousand rubles. This made it possible to call the instrument one of the best in its niche SDS MAX and the price category.

However, due to the need to comply with with safety requirements, MAKITA produces a SDS MAX rotary hammer HR5210C with identical technical characteristics, but with improved safety parameters, first of all, reducing vibration during operation( such additional protection is called AVT): dynamic counterweight(compensates for vibration due to protivohod of the piston), anti-vibration handles and shock absorbers. Immaculately aligned with the standards of Europe, the instrument, however, bought a half kilogram in weight and 4 thousand rubles in value. However, representatives of companies from European countries estimated that spending on improving percussion instruments in the framework of safety equipment is several times less than spending on treating victims of the same instruments, but created without observing strict rules.

liquid lubricant is gaining increasing popularity among manufacturers due to the mechanisms of heavy shock equipment. There are quite convincing explanations for this: liquid lubricant, unlike usual, thickens in the frost rather slowly, is distributed faster by the mechanism of the tool, preventing the reducer from heating, which prolongs the life of the perforator or jackhammer.

The case of is another important detail, the quality of which is directly proportional to the protection provided. The body made of high-quality plastic saves not only the metal parts of the machine, but also its operator from burns, reduces the level of vibration, is an insulator against the impact of electric current.

The opinion that the hull must not be heated during operation is erroneous. However, there is a certain temperature limit of its heating, which is supported by lubrication, ventilation and metal housing, removing heat and cooling the tool. Otherwise, there is a risk not only of burns, but also a shortening of the tool life. Cooling is also served by an elongated handle, which is included in the complete set of perforators, for example, from DeWALT.In addition, the handle is a very useful and convenient part for those builders who often work on a horizontal surface.

As for the heavy drill equipment , the best option in terms of profitability: the purchase of a perforator or jackhammer in a special suitcase, necessary for storage and safe and convenient transportation of tools, and with a maximum of one chisel. It's simple: often manufacturers equip the tool with excessive details and drills, which, in the final analysis, are hardly useful. Therefore, advice for saving: to buy the necessary minimum, picking up later the other necessary elements.

Another company, besides the aforementioned kings in the production of percussion instruments, is HILTI, the principle of which sounds like this: the implementation of exclusively direct sales of manufactured equipment, bypassing suppliers. This is often fraught with complications for buyers from small settlements related to the issue of repair and service. On the other hand, there are numerous laudatory reviews of the company from a large number of buyers and a unique warranty period and service: the elimination of any breakage within 2 years. It remains to solve small problems: how to get the inhabitants of remote villages to the official service center and, of course, to solve the issue with the price. The cost of such miracle machines reaches 98, 5 thousand rubles( like HILTI TE 70).This is a kind of record. And at the same time, for the same price it is possible to buy 4 perforators BOSCH, spare parts to which to find where as it is easier.

The choice of a tool when buying depends primarily on the functions that will be most often used. For the destruction of any structure, the obvious advantage is the jackhammer because its performance in the direct impact mode is several times higher than the perforator of the same class.

How to choose the universal heavy puncher SDS MAX

Often, due to the high cost of tools, the question arises: what is more profitable to take - a punch or a jackhammer. And it is more favorable both from the point of view of cost, and universality of the tool. In the event that such confusion arose, the choice is obvious: a puncher.

Heavy perforators are divided into 3 main groups, based on their weight:

- weight not more than 5 kg;

- weight not more than 7 kg;

- weight 11 kg or more.

The perforators of the middle weight category practically do not concede in functionality to heavy punchers, differing significantly in price. Their main functionality is quite wide: installation of split systems, drilling of wall openings and laying pipes and wiring. The undeniable plus of 7-kilogram tools is also in the possibility of using drills for light perforators thanks to the SDS + adapter. This option will significantly save money.

In order to simplify the choice of punchers, we compare the most popular brands with approximately equal parameters, in one weight category( with the exception of the latter) and the conditions for providing warranty service. This will be the Makita HR4011C, DeWALT D 25600 K, HITACHI DH40MRY, Hilti TE 76-ATS, AEG PN 11 E( heavy puncher).

Makita HR4011C perforator

A fairly new model of the Japanese company, which allows not only to make holes whose diameter does not exceed 45 mm, but also to use hollow drill bits with a diameter of 105 mm. The impact energy of the instrument is 9.5 J, the engine power is 1100 W, the result of such characteristics is an extremely high level of productivity.

Corresponding to all strict safety criteria, the puncher has a number of features that must be noted separately. First of all, this is an increased wear resistance of the metal gearbox due to the coating of the latter with a metal-plastic casing. In addition, of course, the puncher is equipped with a protection against vibration and a unique system of automatic indication of damage to the electrical cable or worn out carbon brushes. The weight of the instrument is 6.3 kg, the price is 18.3 thousand rubles with the manufacturer's guarantee up to 1 year.

Hammer drill DeWALT D 25600 K

The uniqueness of the tool in the presence of a specially designed plastic gearbox body, which does not need to be removed when passing service, which reduces the process several times. Thanks to this successful innovation the ability of the body to remove heat during operation, cooling the tool, and also facilitates access to carbon brushes has increased. In addition, the puncher is equipped with a convenient elongated handle that can be attached to its rear. The power and energy of impact of such a tool: 1150 W and 10 J, respectively. A minor disadvantage of the system is the lack of an AVT system, which is not fully compensated by the presence of shock absorbers. Also there is a system of indication, which allows timely detection and elimination of wear or breakage.

Like the previous contestant, the tool allows making holes with a diameter of about 45 mm. Its weight is 6.8 kg, and the cost is 19.5 thousand rubles. However, for this price( in case of getting into the action, of course) we get together with the perforator the DeWALT D 28942 grinder( power 2.2 kW, diameter of the circle 230 mm) in one large suitcase. In free sale the purchase of such a gift will cost 5,5 thousand rubles.

HITACHI Rotary Hammer DH40MRY

This tool stands out among the colleagues in the design of the hull, in the rest it is similar to those considered earlier. With an engine power of not more than 950 W, the puncher demonstrates the impact energy of 10.5 J. Interest is also a high level of protection of the engine from the ingress of small construction waste during operation. Speaking about protection, we should also mention the presence of an anti-vibration system of the same name. Also, the tool boasts a high frequency of impacts: up to 2650 per minute, which is due to the possibility of electronic engine speed regulation: maximum up to 480 rpm. The holes that can produce a perforator will be a maximum of 40 mm in diameter, with the use of hollow drill bits this parameter increases to 105 mm. The price of such a miracle is 16, 5 thousand Russian rubles.

Hilti model of a large perforator TE 76-ATS

The above-mentioned unique unit among punchers will cost 45 thousand rubles. In exchange, you get: a high engine power of 1400 watts, giving the impact energy to 8.3 Joules;drilling diameter - 40 mm, with the use of hollow crowns - 150 mm maximum. In addition: increased operator safety in the event of possible wedging of the drill, which is provided by the presence of an active torque monitoring system. Also in the kit - an indicator of the level of wear of carbon brushes, a power mode switch and a vibration protection system in the form of anti-vibration handles.

AEG model of heavy puncher PN 11 E SDS MAX

Due to the weight of 11, 8 kg the puncher falls into the category of heavy. In the rating, he came with the goal to visually present the difference between the perforators of different weight categories.

This puncher manufactured in Germany - a new model. It is distinguished, first of all, by the linear setting of the engine, in connection with which it is ideal for work in the horizontal plane or for production in a rather narrow space. Possessing tremendous performance due to the high engine power( 1700 W) and, as a result, the crushing energy of the impact - 27 J. The cost of such a king is 26.5 thousand. The conclusion of the comparison can be done this: having an acceptable price, in terms of characteristics and presented parameters, it significantly exceeds the perforators of the middle weight category.

Conclusions.

Verdict: each heavy puncher has both pluses and minuses, but under the initially set parameters( a small construction team) is most suitable for DeWALT D 25600 K, because:

- angle grinder will not be superfluous;

- lightness, convenience and excellent technical parameters, such as: engine power and impact energy, advantageously distinguish the puncher among others;

- the quality of the products manufactured by DeWALT is beyond doubt;

- The level of service of the company over the past few years has only increased, which causes multiple positive responses, in addition: a variety of pleasant promotions and bonuses have served their service for the benefit of reputation.

In the end, the information presented is based on a purely personal experience and is only a fact-finding activity. Everyone is free to select and choose a tool based on their own perceptions of quality, safety and sufficient service.
