Diamond Reaming Shells are essential high-performance tools designed to be used in conjunction with drill bits. Their primary role is to maintain the specified borehole gauge, ensure the stability of the drill string, and provide critical protection for the lower drill string against excessive abrasive wear during operations.
The helical type reaming shell is specifically engineered to provide an optimized passage for drilling fluids. Constructed with a wear-proof matrix, these tools offer an extended service life even in challenging geological conditions.
