The double core barrel T2 56 has an external diameter of 56 mm. Compared to the core barrels T6, the T2 allows a fast penetration of the ground, a lower diamond cost and a higher core diameter thanks to the smaller cutting surface.

Technidrill offers a complete T2 range. Each double core barrel is composed of a thin kerf and its inner tube on bearings. With this technical expertise, the core is more effectively preserved.

Here are the range diameters: 46, 56, 66, 76, 86 and 101 mm.
Two lengths are available : 1 500 mm and 3 000 mm.
