Talpa Sonic Drilling Products and ROVD Group present a brand-new Sonic drilling head to the market


What is Sonic drilling?

Sonic is an advanced form of drilling that uses high frequency resonance energy that is generated in the Sonic head to drive a drilling string into geological formations. During drilling the resonance energy with high frequencies is transmitted to the drill surface via the drill string. By simultaneously rotating the drill string, energy and impact are evenly distributed over the drilling surface. This special combination of energy blow, ensures that almost all formations can be drilled in (from clay, gravel and sand to rock) with maximum productivity.

Why Sonic drilling?

The high vibration ensures minimal disturbance of the sample due to the physical law of inertia. The mass of the sample simply does not have the time to react to the vibrations of the sampling casing. Our Sonic drill head can even vibrate up to 160 Hertz. This means that the drill string moves up and down 160 times per second, and the drill bit will hit the formation 160 times a second and will also rotate at the same time.

Why for mining?

– High quality soil samples

– Good drilling results in almost all formations (also mixed formations)

– Drilling speed especially in difficult and mixed formations, compared to other drilling techniques

– Less drilling wastes

– Less contamination of the drilling sample
