NQ HQ PQ Reamer Diamond Reaming Shell Hole Opener Reaming Shell
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.
In diamond core drilling jobs, a diamond drill bit is attached to the end of hollow drill rods to cut a cylindrical core of solid rock for examination on the surface, while a diamond reaming shell or called reamer shell is designed to sit above the diamond drill bit or high on the outer tube to ream the hole to the correct constant specific diameters, reducing the possibility of stuck tubes down the hole.
Reaming shell also acts as a stabilizer for diamond coring bits and core barrel during the whole drilling operation, preventing vibration and hole deviation. Helical type reaming shells provides good passages for water flowing, the matrix is wear proof and its service life is long.
