The bit is made from high-quality steel and wear-resistant material, which is welded onto the blades to protect them from erosion.
The body of the bit is created from a single piece of alloy and finished using advanced CNC machining.
The bit has large and deep slots to clean and cool the drilling fluid, allowing for faster drilling and preventing material build-up.
High-performance PDC cutters are used, increasing the bit's ability to drill through tough areas and extending its lifespan.
Different types of PDC cutters are chosen and the bit's design is optimized to suit various drilling conditions and meet different requirements in soft to medium-hard formations.
We can design and produce different bits based on the specific needs of our customers.

1. Soft to mediun-hard formation application.
Medium parabolic crown profile and heavy cutter density provide high ROP in medium to hard formations with medium compressive strength and small abrasive layers.
2. multi-function hydraulics
The deep blade design can get high ROP in medium to hard formations and can effectively cool the bit in hrad and abrasive formations .
3. longer bit life
High intensified gage design provides for long runs on steerable system through hard and abrasive formations as teering application.
PDC ROCK BIT Option Features:
PDC Cutters
Different features of PDC cutters can be chosen in different wells or formations for maximizing both drill efficiency and economic
Gauge length
Short：Improved bit steerability and tool face control for directional or horizontal drilling, reduce slide section by achieve builds more quickly.
Extend：Enhances bit stability and allows more area for gauge protection components, improves bole hole quality.
Active gauge
Protect the gauge and improved hole quality
