High quality steel
Our drill rods are made of high-quality alloy steel, which perfectly balances the wear resistance and flexibility through a special heat treatment process, can meet the requirements of hard rock drilling, and has a longer service life.
Advanced manufacturing technology
Our drill rods adopt a complete set of mature technology such as advanced surface treatment technology, smelting technology, and mechanical processing technology, which greatly reduces the loss of energy in transmission and makes the drilling speed very fast.
We have advanced thread manufacturing technology, which can effectively reduce the risk of indentation and fracture at the thread end, making it easier to connect and disassemble drill rods, drill bits and shank adapters, resulting in shorter downtime, straighter drilling holes and higher production efficiency.
The escrape groove in the transition area between the thread and the rod body is the weakest area of the drill rod, where the drill rod section is the smallest, not only to bear the high-frequency tensile and compressive normal stress, high torsional stress, but also to withstand the additional bending stress caused by the weight of the drill rod and the rock drilling operations.
In drilling practice, QIDELI continuously optimizes the processing technology of the escrape groove, and has our own unique processing technology, which has minimized the risk of breakage at the escrape groove.FAQ
