It is suitable for use on all conventional and wireline core barrel. This product is mainly designed to ream the hole to the standard diameter. It can keep the stability of the core barrel. When the old bit is replaced by the new one, reaming shell can also provide sufficient clearance for the new bit. It can also help to resist the abrasion of the core barrel. This type of diamond tool is physically longer than the standard type. So for the compensation of the difference in reaming shell length, an appropriate inner tube extension is necessary to be used.Ranging from broken and abrasive to consolidated and non-abrasive formations, reaming shells are all suitable to use. We can produce reaming shells with 6", 10" and 18" length.
