External bayonet driver – For the tube
Specially designed for advance drilling systems with Rota casing, the external bayonet driver transmits torque directly to the drilling tube. It is available from stock at our branches.
Mounted on the outside of the casing, it drives the core bit reliably and robustly, while withstanding the high mechanical stresses generated when drilling in difficult ground.
Its bayonet system guarantees fast, secure coupling, reducing intervention time on site.
Available from Ø88.9 mm to Ø609.6 mm.
