Wireline Drill Rods (HQ/PQ Series)

Wireline drill rods are specially manufactured for deep mineral exploration drilling, where core recovery and borehole straightness are critical. Our rods are produced from alloy steels (4130, 4140, 4340), cold drawn, quenched & tempered, and CNC-threaded to withstand high torque and cyclic fatigue in demanding exploration environments.

Common Wireline Sizes

Wireline Series	Outside Diameter (OD)	Wall Thickness (WT)	Typical Application	Steel Grade Options
HQ Rod	Ø159 mm	6 mm	HQ wireline core drilling	4130 / 4340
PQ Rod	Ø194 mm	8 mm	PQ wireline deep core drilling	4140 / 4340
Exploration 4”	Ø101.6 mm	8 mm	Deep exploration (4 in series)	4130 / 4140

Manufacturing Process

1. Material Selection – Alloy steel billets (4130, 4140, 4340, etc.) are tested for compliance.
2. Hot Forming – Billets are formed into tubular blanks.
3. Cold Drawing – Tubes are cold drawn for straightness, uniform OD/WT, and smooth surface.
4. Heat Treatment – Quenching & tempering for high strength and fatigue resistance.
5. Straightening – Multi-roll straightening to achieve tight straightness tolerance.
6. CNC Machining – Rod ends are prepared for thread cutting.
7. Threading – Threads cut with precision CNC machines (API, Q™, T, R-thread available).
8. Surface Protection – Black oxide, phosphated, or galvanizing for corrosion resistance.
9. Final Inspection – Straightness, dimensional tolerance, hardness, ultrasonic/NDT, and thread gauge testing.
