best selling good feedback Reaming Shells:
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.
Reaming shells are produced with diamond panel pads using specially chosen diamonds of 30/40 s.p.c. Although reaming shells generally last 3 - 4 times longer than core bits they should be retired as soon as they wear under gauge otherwise it could result in an undersize bore hole diameter which can mean reaming later.
We also supply made-to-order products according to your detailed requirement.
