Good Quality drill bits made in China Hot selling

Product Description
SPECIFICATIONS OF PDC BITS
1.The bit is suitable for soft to medium soft formations.
2.Cutting structure is force balanced, bit blade is asymmetrically designed, and spiral blade and spiral
gage are also designed so that the load on bit is balanced that resulting better stability of the bit.
3. Multiple types of high performance PDC cutter are strategically arranged on the bit for improved
service life the bit.
4.Shock absorbers are designed to make the bit capable of drilling through formations with hard stringers.
5.Hydraulic system of the bit is optimized using dynamic flow pattern simulation technology to enhance
cleaning and cooling effects of the bit to effectively prevent bit from balling.
6.Erosion on bit surface is effectively prevented by utilizing hardfacing material of highly erosion resistant
and applying advanced base metal enhancement technology.
7.Ports on bit are also optimally designed to prevent erosion of water courses inside the bit.
