Wireline Drill Rod

Exploration diamond drilling differs from other geological drilling, which utilizes an annular Diamond Drill Bit attached to the end of hollow drill rods to cut a cylindrical core of solid rock for examination on the surface. The core does not drop out of the inside of the core barrel when lifted because either a split ring core lifter or basket retainer allow the core to move into, but not back out of the tube. Drilling of 1200 to 1800 metres is common and at these depths, ground is mainly hard rock, so diamond drill rigs need to drill slowly to lengthen the life of drill bits and rods, this drilling method cost are very expensive.

Description of Wireline Drill Rod:

This wireline drill rod is the equipment that connects the Drilling Tools and Drilling Bits, and it is mainly used to transmit power. It mainly consists of a tubing body and two thread ends.

All rods are designed to be compatible with other rods  manufactured to DCDMA
