FAQs
These FAQs explain rod sizing, common lengths, thread wear control, and how casing is selected for hole stability.
What sizes are most common for core drilling rods and casing?
DCDMA-style sizes are commonly used, such as B/N/H/P systems. Availability in DCDMA sizes is widely stated.
What rod lengths are commonly supplied?
1.5 m and 3.0 m rods are commonly offered for many wireline systems, depending on rig and site handling limits.
Why is thread wear a key buying point?
Competitors highlight hardened threads to slow galling and extend joint life. Case hardening up to 60 HRC has been promoted.
Can rods be mixed between different brands?
Mixing is usually discouraged due to fit and safety risk. Matching thread type and tolerance is expected for reliable make/break.
