Diamond reaming shell / Reamer shell / Reamers
Applications: Diamond reaming shell widely used for mineral exploration, geological exploration, water and electricity, soil investigation, hydro-geological exploration etc.
Reaming shells are designed to be placed behind the core bit to ensure hole diameter is maintained and to assist core barrel stabilization. This ensures that when a new core bit is inserted into a continuing bore hole there is a good chance of reaching bottom of bore hole without reaming.
The Reaming shells help protect the diameter of the holes and guide the drilling holes to avoid the holes becoming smaller and holes inclination becoming bigger while the matrix of bits wear down so as to steadily drill.
Material: PCD, surface set, electroplated, T. C. Reaming shell
