Drilling rods - Import export

In cooperation with Sandvik we are producing vast variety of drilling rods with different cross section, shape, length and connection tips and ends. We also have wide range of accessories, couplings, extension pieces and wrenches. For these products and accessories we use highest quality material as we know that it is important for high performance and safety.

EWS takes measures against vibrations in deep drilling procedures Deep drilling procedures with drilling rods with a long overhang are one of the most demanding tasks in cutting technologies. What influences vibration, what amplitudes does it create, what is the effect of superimposed vibration and when are uncontrollable resonances encountered? All these are questions that are difficult to answer using theory alone. These findings formed the basis for the new development of EWS Rigid. The objective was to create a drilling holder with a passive damping system to counteract the vibrations that are created. This involves using variable vibration dampers with linear degrees of freedom in a floating mounting inside the cutter carrier. The damper position is set using a radially mounted setscrew, which allows optimum vibration conditions to be created. The improvement in surface qualities of bores is significant, as is the increase in the service life of cutter tools.

We produse drill bits with PCD and TC blades for rotary drilling, which are used for exploration drilling, anchor holes, degassing holes, special drilling applications and blast holes. While designing our bits, we always consider type of ground to be drilled, requested diameter, flushing requirements and media as well as connection to drill rods and tubes. We are extremely flexible with our design and production, being able to respond very quickly to all customer requests for special shapes of bit bodies, geometry and lay-out of cutting blades, number and sizes of flushing holes and many more.
