Conventional core drilling

Conventional core drilling systems are used for shallow site investigation and shallow to medium deep underground uphole 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.

Diamond and tungsten carbide coring bits – a comprehensive range of core drilling tools for reliable site investigation.

• Diamond impregnated drill bits for soft to very hard rock.

• Surface set diamond drill bits for soft to medium hard rock.

• Polycrystalline diamond compact (PDC) drill bits for non consolidated medium to hard rock.

• Tungsten carbide (TC) for soft rock formations and overburden drilling.

Thanks to the Terracore bit range there is always a solution to match the variety of rock conditions encountered.

The main focus is on soft to medium hard rock formations – both consolidated and fragmented. There are also tools for drilling in concrete.

Conventional core barrels and overshots – rugged construction and design

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 rods and casings – lightweight steel or aluminum for ergonomic flexibility.

Conventional drill rods are available in lightweight steel or aluminum, providing you an ergonomic flexibility which will improve your handling capabilities under the most strenuous conditions. Steel drill rods are manufactured with friction welded hardened steel couplings. Aluminum drill rods are manufactured with glued, threaded hardened steel couplings.

Our drill rods and casings are of the highest quality, delivering top level performance to your equipment and drill site. Whether you are using our specially designed wireline or conventional drill rods, we will ensure you superior productivity every time.
