Tri Tornado Dual Stage

Our hole opener boasts a series of features that underpins its performance:

The smooth transition on the body OD reduces the chances of debris build up and packing off. The spiral body blades and pilot blades encourage directional turbulent flow, removal of cuttings/debris and excellent hole cleaning.

This unique hole opener has offset positioned cutters to allow a more aggressive cutting effect and strategically placed upward facing nozzles to encourage flow and ensure the cutters stay free of debris. The nozzles are held in retainers and are not machined as part of the integral body, enabling easy replacement and preventing body damage from washing. 6 cutter design for maximum ROP performance.
