Construction, road engineering, mining and installation work – 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 specifics of specific works?
Hardness is one of the parameters that most determine the wide application of concrete in construction and engineering. It has a beneficial effect on the durability and functionality of structures, but for contractors it is associated with certain difficulties. 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 allow for safe and precise 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, also allows for avoiding dust, which has a positive effect on maintaining order and the health of employees. How do drilling rigs work? How much do they cost? How to choose the right drill bits for a drilling rig? We discuss these issues in the following entry.
What is a drill rig?
drills (borers) or crowns . In our offer you will find high
quality crowns from renowned manufacturers such as Rothenberg or Modeco Expert ;pressure tanks for supplying water (used in the wet method);
collars for draining water;
extensions increasing the working range (usually by several dozen centimeters);
tripods used to ensure drilling accuracy;
beams spacers for better tripod stabilization;
vacuum cleaners (thanks to them, dust does not accumulate in the opening, does not contaminate the workplace and does not enter the employee's respiratory tract and eyes);
grinders enabling the processing of drilled holes.

The different types of substrates and materials, as well as the conditions at the workplace, determine the use of drilling machines with different types of drives. In this respect, the following can be distinguished:
electric drills : their advantages include low weight and affordable prices. However, they require access to the electrical grid or a generator, which, combined with the presence of a cable, often makes work difficult;
Gasoline drills : provide high power and do not require connection to a power source;
pneumatic drills : powered by compressed air, they enable safe work where the use of electric or combustion models would be associated with danger.
Drills can also be divided according to their operating mode. In this classification, there are:
rotary drills processing the material with rotational movements;
impact drills , the operation of which is based on the impact of the drill bit on the material;
vibratory drills crushing material through high-frequency vibrations;
rotary-percussion drills 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. That is why at the Onninen wholesaler we only offer you 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 a drill and accessories, the selection of the right drill is also of great importance for work efficiency and safety. Due to the high hardness of the materials processed using drills, drills intended for them are primarily made of diamond or cemented carbide. They come in several variants, the most important of which are:
core drills made of diamond : they enable the production of large holes
diameters with reduced risk of tool damage. Drill bits are available in wet drilling versions (equipped with a water tank for dust removal) or dry drilling (intended for use with a vacuum cleaner);carbide drills made of cemented carbide : due to the higher risk of damage, used primarily for simple assembly work;
special drills : e.g. with a flat head and with a multiple (double or quadruple) blade. Used primarily to penetrate the next 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 from PLN 8,000 to slightly over PLN 16,000. Of course, the prices apply to the devices themselves, without accessories. In case of problems with choosing the right model and equipment, you can count on professional help from our employees. After logging in to the onninen.pl online wholesaler, we offer our customers lower prices with individual discounts.
