Product Description

NTW Core Barrel Completely 3 meters Length for Wireline Core barrel Drilling

 

 

CORE BARRELS, BITS, RODS, CASING AND TOOLS
 

Roschen offers a variety of high quality coring drilling systems which include core barrels, core diamond drill bits, drill rods, casings and more.


Surface & Underground double tube thin wall wire line core barrels are used in select mineral exploration applications. Using thinner walled cross sections for rods, tubes and diamond bit kerfs creates a larger core sample within nominal 'A' and 'B' bore holes. The design allows for ease of use with clear water common in underground environments or less dense drilling additives when required, and are typically chosen for more competent ground conditions and for use with high speed drills having lower pull down forces.
