Drill Rod Advantages

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.

Strict quality control

We strictly control all aspects of production to ensure that high-quality drill rods are presented to customers.
