Atlas Copco Wireline core barrel N2 N3 NEW latching system Improve 30% Faster Penetration Rates
Thinner walls and tighter tolerances enable Roschen to offer a
lighter weight core barrel, and when used with Roschen’s thin kerf
bits, decreases the surface area for up to 30% faster penetration
rates. These systems feature a number of unique innovations
including ITIP valve for landing indication and integrated pump out
for triple-tubes.
Roschen’s thin kerf coring systems offer many advantages for both
surface and underground applications — the geologist can log a
larger core sample from a similar sized hole and the driller is
able to work under more ergonomic conditions. Contact your local
Roschen representative to get more information.
Roschen recommends using only Roschen quality manufactured parts.
Roschen does not guarantee the consistency or quality of other
manufacturers.

Features:
1. Wireline system which affected the rod and core barrel design
and incorporated the use of a wireline overshot.
2. Triple-tube system which effected the core barrel and the bit
design and allowed for a second split inner tube to be used so that
an undisturbed sample of very broken core could be viewed in its
original state.
3. Thin kerf or light weight systems which effected the design and
dimensions of the entire drill string to allow for a larger core
sample to be retrieved at increased depths or in similar sized
hole.
