| Reaming shells are utilized to maintain the hole gauge and stabilize the drilling system during the operation drilling in the hole. |
CDG’s reaming shells are made with high-quality, synthetic and natural diamonds, embedded in a highly resistant matrix. They have additional protection made from friction-resistant tungsten carbide to maximize lifespan, and their maximum active surface helps to limit deviation. Spiral waterway canals that are wider than standard design type and as such reduce the potential for blockage by pebbles or other debris.
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.
CDG’s reaming shells are available in industry standard lengths of 6" ( 1 pad), 10"( 2 pads) and 18" (3 pads or 4 pads). Oversized reaming shells are available according toy our request.
