Conventional Core DrillingMoreinformation

conventionalcoredrilling

Conventional drilling remains the most productive and cost efficient method in some applications, like short horizontal/uphole underground drilling and shallow surface site investigation and geotecnical projects.

Conventional core drilling systems are used for shallow site investigation and shallow to medium deep underground up-hole definition drilling applications. They are efficient solutions due to their operational simplicity and inexpensive tooling. The entire string has to be pulled out of the hole to collect the core samples.

Drillers can enjoy Atlas Copco's latest innovations in core drilling tools to boost productivity and stay on top of the competition race.

Conventional core barrels and overshots

A comprehensive range of core drilling tools for reliable site investigation.

Conventional core barrels produce a larger core diameter compared to equivalent wire line size. The rugged construction and design features ensure optimization of productivity in applications where the use of wire line system is not practical or cost effective.

Conventional core barrels are typically used in shorter bore holes. The core barrels can drill in all directions.

  • Faster penetration.
  • Lower diamond cost.
  • Larger core.
