Core Drilling Tools NQ Reamers Reaming Shell

Core Drilling Tools NQ Reamers Reamiing Shell

The reaming shell is an integral part of a diamond drilling system and acts as a coupling between the core bit and the outer barrel. It reams the hole to the proper size, and stabilizes the bottom of the drill string.

Reamers feature increased stability and reduced vibrations due to the specially designed spiral pads, which provide increased contact with the circumference of the hole. Our reaming shells experience longer life in the field due to the greater number of diamonds and hign grade carbide reinforcements.
