ATW BTW NTW HTW double tube core barrel assembly thin wall core wireline system
Specifications:
1. Available for application in standard DCDMA hole sizes ( B, N, H, P).
2. Ideal for use in most drilling conditions
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.
Features:
1. Cost-effective maintenance
2. Superior solution for on-the-job-safety
