Detailed Product Description

Impregnated Core Drill Bits T2 Double tube For Geological Exploration




T2 Double tube core barrels are widely used and suitable for coring in all hard and soft formation, with water flushing and poly. 


T2-86 diamond-impregnated core bit
1. Diamond bit ISO
2. OEM diamond bit
3. diamond bit high quality
4. Best sale diamond bit



Specialisted in producing varies kinds of diamond core bits in different international standard size for soft, medieum to hard rock formations. 

Including impregnated diamond core bit, surface-set diamond bit, reaming shells, impregnated diamond casing bit, casing shoe bit, TC core bit, TC casing bit, diamond reaming shell, corelifter, corelifter case, diamond sub-adapters, hoist plugs, tap, etc.

With ISO certificate & quality control.





Impregnated diamond core bits (NQ, HQ,T2-86, etc.) are widely used in mineral exploration industry, site investigation, etc.

The impregnated diamond core bit has emerged as the most commonly used type in the mineral exploration industry. The advantages of using impregnated diamond core bits over bits manufactured with other cutting media include:

An extremely wide range of application.




To select the right bit for the job, assess the speed and power of your drill for the size and depths of the holes to be drilled and assess ground conditions such as rock type/formation and down-hole conditions.



ROSCHEN  bits are available in all standard drilling sizes . Also, non-standard sized bits can be produced according to requirements from clients.

Crown Height:
ROSCHEN offers crown impreg depths of  9mm, 12mm, and 16mm .The taller crown heights provide improved bit stability and reduced vibrations, enhancing bit life and performance.


Various waterways are available for diamond impregnated bits. Differing waterways allow for better flushing in various ground conditions and drilling systems.


ROSCHEN impregnated bits matrices can be selected by our engineer according to ground conditions at client's work site.





standard Q threads as well as thread types required by clients are available.





1, Being widely used in the geological exploration industry, penetrating formations from the softest to the hardest rocks.

2, Steel core body with diamonds mixed evenly through a tungsten carbide matrix.

3, Fast penetration rate , best recovery and long life. 4, Item Size: HQ, NQ, BQ, AQ, FQ, T series, etc5, Item Package: Cartons and Pallets


Working principle:


1. Core barrels with a double tube system for drilling in homogeneous and partially broken formations . The thin kerf design provide a good penetration rate.

2. The inner tube is not rotating, and maintain the sample inside by preventing that fluid circulation wash-out the core, as happens in the single tube core barrel.

3. This type of core barrel is suitable for hard formations due to the small cutting area, achieving a high core recovering.

Provide a good bending resistance and wear of all its components.

All standard drilling diameters are supplied, from 56 mm to 101 mm.
