Core Barrel with Rolling Bits is a drilling tool designed for drilling in very strong rock formations.
Main diameters: 520 mm, 650 mm, 700 mm, 780 mm, 900 mm, 1060 mm, 1350 mm, etc.
Larger and non-standard diameters are also available.
The core formed during drilling is delivered to the surface along with the Core Barrels, or it is destroyed by a free-falling bit or rock auger. The Core Barrels we sell are made of high-quality alloys, which allow you to achieve the necessary strength to ensure the reliability and long-term operation of the tool. The use of wear-resistant materials in places subject to the greatest stress allows you to extend the life of the tool for a long time.
The standard connection type is a 200 x 200 mm square. Other sizes are available upon request.
They are used to construct bored piles (deep foundations) with a Kelly bar.
