Product Advantages
High-quality steel
Our drill bits are made of high-quality steel and cemented carbide as raw materials. After a special heat treatment process, they can meet the requirements of excavating harder rock layers and have a longer service life.
Advanced thread manufacturing process
Our drill bit adopts advanced thread manufacturing process, which makes it easier to connect and disassemble the drill rod, resulting in shorter downtime, straighter drilling holes and higher productivity.
Strict quality control
All the drill bits are strictly controlled to ensure that they have a satisfactory high quality.
