Mounting guns for working with hardware are widely represented in the domestic market. Pneumatic models are the most popular due to their high performance, accuracy and affordable price. However, in professional construction and complex household repair tasks, it is more expedient to have a gunpowder assembly gun on hand, which is distinguished by high impact energy and reliability.
Features of powder mounting guns
The main feature is high power, which allows the user to work even with thick dowels. In this case, any solid material can act as the basis. Of course, the family of gunpowder models also has its own gradation in terms of impact force, but even the middle segment offers characteristics that significantly exceed the capabilities of alternative tools. Suffice it to say that the gunpowder mounting gun is capable of confidently fixing brickwork to steel and concrete, which is confirmed by practice.
The choice should take into account the technical and operational characteristics of the pistols so that they fully meet the requirements at the place of operation. For todayToday, this segment is not very popular, since the function of direct impact driving is quite specific. This is why the market is dominated by Hilti powder-actuated mounting guns, which have practically no competitors equal in quality. But on the other hand, there is competition within the family, so before buying, you should familiarize yourself with the specific offers of the brand.
Specifications for Hilti DX E72
This is the basic version in the manufacturer's line, which is distinguished by sufficient power for medium construction needs and modern ergonomics. As for the technical data, the model has an impact force of up to 362 J, and the range of fastener lengths varies from 14 to 72 mm. At the same time, it should be noted that tools with a high power potential usually look quite impressive. In this case, the developers managed to combine compact dimensions with good impact energy. In particular, the Hilti DX E72 powder-actuated mounting gun has dimensions of 404 x 46 x 153 mm. The mass of the tool is only 2 kg, which allows you to conveniently perform work with one hand.
Specifications for Hilti DX 76
This is a more serious model that can safely be classified as professional. The impact energy of this device is 563 J. This indicator is enough for the operator to easily work with the installation of steel products and structures, realizing strong connections. True, the dimensions of the case in this case will also be rather big - 45 x 10, 1x 35.2 cm with a weight of 4.3 kg. It is also important to note the performance of the DX 76 model. The gunpowder mounting gun of this modification is capable of serving fasteners with a length of 19-21 mm. It is impossible to talk about such opportunities even in relation to the leaders in the families of the same pneumatic or electric mounting guns. The advantages of this particular model, in addition to the powder method of supplying energy, include the implementation of an automatic clogging mechanism. This means that the device will cope with high loads without compromising the quality of the operations performed.
Specifications of the Hilti DX 2 model
This modification can be attributed to household models. It effectively copes with metal and wooden bases, accurately hammering hardware with a length of 14-62 mm. At the same time, the impact force is very modest by the standards of professional tools - only 245 J. Nevertheless, this is enough to fix wooden materials to concrete, fasten plywood sheets and formwork boards. Also, the Hilti DX 2 gunpowder gun is suitable for installing masonry to steel and concrete. The range of operations includes fixing drywall guides, fixing electrical and mechanical elements to concrete surfaces, installing plaster mesh, etc. The unit measures 34.5 x 5 x 15.7 cm and weighs 2.4 kg.
Consumables and accessories
For stable and high-quality workgun requires the appropriate equipment. For example, an important role is played by the piston guide in the mechanism, on which the impact force depends. Usually, kits also include a set with a piston and retaining rings - these elements can be replaced by the user if necessary. Particular attention should be paid to the choice of cartridges. The fact is that gunpowder construction mounting guns work with consumables of various formats. The most common cartridges are DX modification M10, which are used in work with siding, ceilings, etc.
Maintenance details
It has already been noted that retaining rings and pistons can be replaced by hand. This must be done as it wears, so that the gun stably maintains its function. The resource of these components is determined by many operational factors, including the number of shots fired, the conditions of use, the power of the device, the strength of the case, the level of professionalism of the performer, etc. In conditions of intensive work, the mounting gunpowder should be checked at least twice a day. The piston is replaced in cases of deformation or when chips form on the inside of its end. The processes of curvature of the tip are also common. Retaining rings should also be carefully checked, which can be flattened and split. As a rule, base sets also contain a copy of the new ring, so by comparing the shapes of the two elements, you can easily determine the degree of deformation ordamage.
Conclusion
Hilti is one of the leaders in the percussion construction tool segment. In addition to mounting guns, in its lineup you can find powerful drills and punchers, which will be a serious help in the complex work of repair operations. So, for beginners, the DX E72 modification is suitable. The powder-actuated assembly gun in this version copes with most typical operations related to the provision of fasteners. For professionals, developers offer the DX 76 model, which is characterized by high power. If we talk about comparing the group of powder pistols as such with other variations, then their obvious advantages include ease of maintenance and convenience in the process. The fact is that the device practically does not require the use of auxiliary equipment during operation, which greatly facilitates the production and repair process.
