Introduction
The bit is made of high-quality steel and wear-resistant material. The material with high performance is welded onto the surface of the blades to prevent erosion of the main material.
The body of the bit is created from a single alloy forging and finished using advanced CNC machining technology.
The bit has deep and wide slots to remove debris and cool the drilling fluid. This helps in fast drilling and prevents the formation of clumps.
High-performance PDC cutters are used, which enhance the ability to drill through tough layers and provide a longer lifespan.
Different types of PDC cutters are chosen and the design of the bit is optimized to match various drilling applications in different formations. This ensures that different requirements are met when drilling in soft to medium-hard formations.
We can design and produce different bits according to the specific needs of our customers.
