REAMING SHELLS
Ensure a 360-degree holes wall contact, which maximizes shell stability. Longer life is therefore achieved due to the smoothness of the drilling and the hold gauge maintained. The diamond pads are reinforced with tungsten carbide inserts on the leading edge, which reduces the erosion of matrix around the diamonds by forcing the abrasive cuttings up the waterways and not allowing it to travel across the face of the diamond pad. |
