Miroc drilling NQ Reaming shells High Grate Carbide couple the drill bit with the core barrel

 

Reaming shells

Reaming shells are placed behind the drill bit on the core barrel to maintain the correct hole diameter and stabilize the core barrel.

A reaming shell has to be replaced when its diameter becomes less than the diameter of the new bit. In this way only the very last part of the hole has to be reamed when a new bit is inserted. A reaming shell also helps to stabilize the core barrel. Reaming shells are available for all types of core barrels and drill bits.
Surface set reaming shells Standard surface set reaming shell set with specially selected diamonds and PDC pins. Well designed
waterways, reinforced with PDC pins, facilitate effective flushing and contribute to long service life and good drilling economy for both reaming shells and drill bits.
Reaming shells are avialable in different designs:
10" Double ring reaming shell available only for BQ, NQ, HQ (need inner tube adjustment).
 FH special heavy duty design for long life with extra stabilization.
STD (Standard design).
