描述:
Large diameter bits (from 393.7 mm) with unsealed support. Designed for drilling the upper sections of the well (direction, conductor). The absence of sealing elements in the support allows you to select the maximum dimensions of the paw pin and rolling elements and to carry out abundant circulation of flushing fluid in the support, which is very important to reduce torque, ensure quick cooling and increase the stability of the support.
