(HQ) Drill Rod Φ88.9X77.8X5.5 Wireline Drill Rod for drilling rig
Sinocoredrill WIRELINE drill rods are manufactured from the best
quality cold drawn seamless steel tubes. Ultimate tensile strength,
high precision and straightness more than 1:1800mm provide the best
performance under the most demanding drilling conditions.
Our drill rods(HQ DRILL ROD) are all manufactured by CNC machines.
They're made of high quality alloy steel with heat-treated. We also
can produce various sizes of casing tubes. Our NC&HC (HQ)drill
pipe/drill rods got most praise from oversea market.
The tapered (conical) threads lock secure, couple and uncouple easy
and they perfectly mate eliminating leakage of drill fluids.
Hard chrome plating on box ends protects thread connection and
increases its wear resistance and rods life. Alternatively, both
ends may be case hardened with nitriding, if requested.
All WIRELINE drill rods are flush jointed.
Suitable for deep hole drilling and available in sizes P, H, N,
