Reaming Shells PCD bq nq hq pq Reamer For Diamond Core Bits
Leading manufacturer of series BQ, NQ, HQ, PQ diamond core bits, diamond reaming shell and so on.
Applications: Diamond reaming shell widely used for mineral exploration, geological exploration, water and electricity, traffic construction, building, 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.
Reaming shells are produced with diamond panel pads using specially chosen diamonds, 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.
Reaming shell is set with natural or synthetic diamond, and it is used to couple the drill bit with the core barrel. Its main function is to ream the hole to the correct constant specific diameter which ensures adequate clearance for the core barrel and sufficient clearance for the new bit which replaces an old one. It also acts as a stabilizer for drill bit.
We can manufacture all kinds of diamond bits and reaming shells according to customer's special requirement, reaming shell can penetrate a broad range of formations from the sofest to the hardest rocks.
