Reaming Shell

Reaming shell is an important drilling tool connected between diamond drill bits and core tubes in geological drilling, engineering construction and other fields. It mainly plays a role in expanding the aperture and repairing the hole wall, ensuring that the aperture does not shrink, and providing stable and accurate drilling conditions for subsequent drilling work. The upper and lower ends of the reamer are made of steel structure, which has high strength and good toughness, and can withstand various stresses and pressures during drilling. The outer diameter of the reamer is slightly larger than the diameter of the diamond drill bit (usually about 0.5 to 2 millimeters larger), which can quickly and accurately enlarge the aperture and improve drilling efficiency. We offer a variety of specifications and models of diamond hole openers to meet the needs of different hole diameters and drilling depths, such as common specifications including ф 59, ф 75, ф 91, ф 110, ф 130, ф 150, ф 171, etc. The diamond reamer we produce is easy to operate, with a reasonable structural design, simple and convenient connection with diamond drill bits and core tubes, and easy for operators to master and use. Avoid forcibly drilling in hard or loose geological conditions to prevent damage to the reamer.
