PDC Bits' ,Diamond Bits' cutter exposure is optimized to insure the bit can achieve higher ROP is soft to medium formations.
1.Cutting structure is force balanced and bit blade is asymmetrically designed so that the load on bit is balanced that resulting better stability of the bit.
2.Main cutter are high performance PDC cutters to insure service life of the bit while improving ROP.
3.Cutter exposure is optimized to insure the bit can achieve higher ROP is soft to medium formations.
4.Shock absorbers are designed to make the bit capable of drilling through formations with hard strigers.
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.
We can design and manufacture according to customer's requirement of the Bit Dia\No. Air holes\carbide button shape and the face shape. High air pressure and low air pressure.
All products are compatible with many products manufactured by , Atlas Copco, etc, all our products are widely used in mining, tunneling, quarrying, construction, and civil engineering project.
