Reaming / Stabilizing

Dimatec offers various accessories for use with or in place of reaming shells. These include:

Reaming Shell Field Gauges

These gauges are used at the drill site to measure the minimum permissible set diameter of a reaming shell’s gauge ring. Working reaming shells that fully pass through a field gauge should be taken out of service to prevent the possibility of an undersized drill hole. These field gauges are manufactured from hardened tool steel and have a ground gauging surface. They are available for most standard sizes of reaming shells.

Reaming Shell Substitutes

These are steel adapters that are used in place of a reaming shell where stabilization of the core barrel is not required. They are manufactured to the same physical dimensions as a diamond set reaming shell but do not include any form of a gauge ring.

Inner Tube Extensions

These thin-wall threaded steel tubes are used to extend the length of the inner (core) tube of a wireline core barrel assembly in cases where an extended length reaming shell is in use.


“325 meters with our bits very good in medium hard rock. Thank you!”

– Ontario, Canada

“The successful trial results of the bit prove this bit to be a serious alternative to our current bit of choice at our mine.”

– Australia

“I have a result from a new client in northern Ontario. Their last bits went 60 or 80 meters and with Dimatec bits 212 meter! Good production thank you.”

– North America

“We received the bits yesterday! We are quite pleased with all aspects of this order including the 4-day lead time. Thank you for the expedited service!”

“The meters drilled were above ‘the norm’ and we were well within and even under budget lets say…”

– Canada

“We had a good wear on the crown, the meters achieved are also worth commenting on being consistently all right around the 300’ mark. We’re happy and the reaming shells are also performing well.”

– North America
