Construction, road engineering, mining industry and installation works - these are just some of the applications of drilling rigs. What do you need to know about these devices? How to choose a model adapted to the specific nature of specific works?
Hardness is one of the parameters that largely determine the wide use of concrete in construction and engineering. It has a positive effect on the durability and functionality of objects, but it causes some difficulties for contractors. Most often, they concern concrete processing - especially drilling. Similar problems also occur in the case of reinforced concrete and asphalt, as well as rock or soil substrates.

Drilling rigs enable safe and accurate drilling of holes in these materials. Devices of this type significantly improve construction, renovation and installation work. Their design, thanks to the use of dedicated vacuum cleaners, allows them to avoid dust, which has a positive impact on maintaining order and the health of employees. How do drilling rigs work? How much are? How to choose the right drill bits for a drilling rig? We discuss these issues in the entry below.
What is a drill rig?
drills (borers) or crowns . Our offer includes high quality
quality crowns from renowned manufacturers such as Rothenberg or Modeco Expert ;pressure vessels for administering water (used in the wet method);
collars for water drainage;
extensions increasing the working range (usually by several dozen centimeters);
tripods used to ensure drilling accuracy;
beams expansion joints for better stabilization of the tripod;
vacuum cleaners (thanks to them, dust does not remain in the opening, does not pollute the workplace and does not get into the employee's respiratory tract and eyes);
grinders enabling the preparation of the holes made.

Specific types of substrates and materials, as well as conditions at the workplace determine the use of drilling rigs with different types of drives. In this respect, the following stands out:
electric drilling rigs : their advantages are low weight and affordable prices. However, they require access to the electrical network or a generator, which, combined with the presence of a cable, often makes work difficult;
petrol drilling rigs : provide high power and do not require connection to a power source;
pneumatic drilling rigs : powered by compressed air, enable safe work where the use of electric or combustion models would pose a risk.
Drilling rigs can also be divided according to their operating mode. This classification includes:
rotary drilling rigs processing material with rotary movements;
percussion drilling rigs , whose operation is based on the impact of the drill on the material;
vibrating drilling rigs crushing material thanks to high-frequency vibrations;
rotary percussion drilling rigs using a combination of impact and rotational motion.
It is very important that the drilling rig is made with precision and using modern, efficient components. Therefore, at the Onninen wholesaler, we only offer devices from recognized and proven brands - e.g. Rothenberger , Modeco Expert and Baier/Wolfmann .
Drill bits for drilling rig
In addition to the selection of the drilling rig and accessories, the selection of the appropriate drill is also important for work efficiency and safety. Due to the high hardness of materials processed with drilling rigs, drills intended for them are made primarily of diamond or sintered carbide. They come in several variants, the most important of which are:
crown drills e made of diamond : enable making large holes
diameters with reduced risk of tool damage. Crowns for drilling rigs are available in versions for wet drilling (equipped with a water tank to remove dust) or dry (intended for use in a set with a vacuum cleaner);Widia drills made of sintered carbide : due to the greater risk of damage, used primarily for simple assembly work;
special drills : e.g. with a flat head and multiple (double or quadruple) blades. Used primarily to penetrate another layer of concrete.
How much does a drilling rig cost?
The prices of drilling rigs depend on several factors - primarily the quality and power of the device. When it comes to models for professional use, the purchase of the simplest drilling rig costs from PLN 4,000 to PLN 6,000. More advanced variants in our store's offer are available at prices ranging from PLN 8,000 to just over PLN 16,000. Of course, the prices refer to the devices themselves, without accessories. If you have problems selecting the right model and equipment, you can count on professional help from our employees. After logging in to the online wholesaler onninen.pl, we offer our customers lower prices with individual discounts.
