Features of the selection and operation of Sturm rotary hammers

Construction or renovation work is impossible without the use of special tools. One of them is a perforator. This is a device equipped with a percussion mechanism. With its help, you can effortlessly chalk walls, make holes for dowels in concrete bases and perform a number of other tasks. If you plan to carry out such work, you should take a closer look at the Sturm rotary hammers. They have an optimal price / quality ratio.

Sturm is a company known in Russia for over 15 years. Its production facilities are located in China (there are 40 factories in the Celestial Empire). This company owns several trade marks:

• Sturm;
• Hanskonner;
• Energomash;
• BauMaster;
• "Union".

All products sold are developed and manufactured with the participation of engineers from European countries, America and Japan. The Sturm company focuses on a wide consumer audience and therefore produces both household and professional equipment. The product catalog is extensive. The manufacturer produces gasoline-powered tools, various machine tools, power equipment, heating devices, and electrical equipment. The last group includes punchers.

Sturm manufactures equipment taking into account Russian conditions. There are about 200 service centers in the Russian Federation, where the consumer can get answers to questions of interest or hand over the equipment for warranty repair. It is also not difficult to buy components or new spare parts. Every year the company is increasing the scale of production, offering consumers improved models of power tools.

Rock drills Sturm are available in two versions - with a horizontal engine and vertical. Each of these models has its own characteristics. For example, horizontal (they are also pistol) are distinguished by more convenient operation and less weight. These are budget options designed to solve small household repair tasks. Their disadvantages include weak performance, rapid heating of the engine, which makes it impossible to carry out long-term work.

Vertical rock drills Sturm (barrel) - durable and "hardy" equipment designed for heavy work. In comparison with pistol "brothers" such devices are more weighty and productive. They have a better cooling system, thanks to which the engine heats up less intensely when drilling stone or concrete for a long time. The advantages of such models are high power and the ability to withstand heavy loads. The disadvantages include their high cost, as well as large weight and dimensions.

Sturm manufactures rotary hammers with SDS Plus and SDS Max chucks (variation of drill retention). Most low- and medium-power devices are equipped with the first. This chuck has a 10 mm shank diameter. This size is enough to install a drill with a diameter of up to 30 millimeters. SDS Max has 18mm shanks. They are designed to accommodate large extension drills.In addition, the manufacturer has equipped some models with jaw chucks that are suitable for installing conventional drills.

The Sturm rock drills support several working modes.

• Drilling. This mode is used to make holes for dowels in various materials (aerated concrete blocks, brick, foam concrete).
• Drilling with a blow. This mode is necessary for drilling concrete, stone, cast or porcelain stoneware substrates.
• Impact mode. In this case, the device works in a reciprocating rhythm. The chiseling function is needed for chipping walls for wiring or creating holes using a flat chisel. But for making deep holes, this mode will not work, since it will lead to jamming of the drill.

Correctly selected drilling equipment can facilitate construction and repair work. Before choosing, you should carefully read the technical characteristics of the device. The main one is the maximum impact energy, which determines the performance of the device. The Sturm company produces rock drills with various characteristics, so the consumer has a lot to choose from.

For home use, there is no need to buy productive and powerful devices - the end will not justify the means. In this case, it is best to take a closer look at low-power equipment, the energy of which will not exceed two joules. It will perfectly cope with the tasks of making holes for anchor fasteners or dowels.

Also, the impact frequency is considered an important parameter. This indicator, along with the impact energy, determines the speed of the tool. The more often the piston reciprocates, the less time it will take to make the hole. For short-term work, it is best to select equipment with a horizontally located motor, while vertical models are suitable for long-term slitting or drilling.

The hammer drill may include some important options that will make the job easier for the user.

These include:

• the presence of a limiter for the length of drilling;
• device for smooth switching of speed modes;
• receiver (reverse start of the shaft in the event that the drill gets stuck in the material);
• locking the power button;
• anti-vibration system.

Whether these options are needed or not is up to the buyer. It is important to choose what is really useful, since there is no need to overpay in rubles for those functions that the owner of the equipment will never use.

Due to violation of the rules for using a puncher, its service life is significantly reduced. That is why it is important to follow all the manufacturer's recommendations for the use of drilling tools. The following rules will help keep your equipment working for years to come.

• In order for the perforator to serve for a long time, it should not be allowed to overheat. In the process of slitting or drilling, it is necessary to pause to cool the engine.
• It is not recommended to drill a deep hole "in one go". It is necessary to stop, pull out the drill and remove construction debris.
• When slitting, do not make a lot of effort, with emphasis pressing on the tool. Such actions will lead to premature failure of the striking mechanism.

• The tool should be placed strictly perpendicular to the base in which you want to make a hole.Even the slightest misalignment causes mechanical damage to the cartridge.
• Manufacturers recommend using the grease of the same name, chucks and drill bits.
• Regular lubrication of the working parts of the rock drill is a prerequisite. Pay special attention to the shank. And you should also monitor the condition of the anther and brush of the motor - they need to be cleaned (sometimes replaced) when dirty.

Perforators Sturm reviews are very controversial. Basically, they are satisfied with those users who bought a tool for household purposes for rare and short-term use. In this case, the equipment works flawlessly - exactly as the manufacturer positions the functioning.

Those who bought a Sturm rotary hammer for professional use or for large-scale construction and repair activities were disappointed in the purchase. In their opinion, the equipment does not correspond to the characteristics declared by the manufacturer.

Among the advantages, users of household and professional models noted:

• budgetary cost;
• small weight and size indicators;
• the presence of three operating modes;
• ergonomic body.

Consumers attributed the main disadvantages to the low build quality, due to which the device quickly breaks down, loud operation and a short wire.
