13mm,16mm,19mm PDC cutters for oilfield

The polycrystalline diamond compact (PDC) cutter is compact of a polycrystalline diamond layer and a tungsten carbide substrate. The polycrystalline diamond layer possesses extremely high hardness and abrasion resistance, whereas the tungsten carbide substrate would greatly improve the toughness and weldability of the whole compact.

GK PDC cutters

GK PDC cutter is a Chinese name “Gang Kui” for short, it looks like a helmet. It features higher impact ressistance. With high speed, fix good, long service time, when drilling using the GK products. It is not only useful in homogeneous strata, but also in broken rock or peeble rocks. 

SDB ---- Diamond Hammer Bit Inserts Series

SDB is a proprietary product of our company. The products have replaced the traditional tungsten carbide inserts, usually applying to roller bits, air hammers and DTH(down-the-hole) bits and so on, especially in hard and complicated layer drilling. We adopt advanced technical formula and synthetic techniques from abroad. Using the hyperfine diamond powder as raw materials, the diamond layer can reach 2-3mm. The sintering technologies that we use to make this type of the PDCs, which can form stable D-D combinations between molecules, have greatly improved its durability and toughness, and have prolonged its service life. Our special techniques adopted in the combination of diamond and kentanium, which make the WC dissolve into the diamond under extremely high pressure and temperature, can also ensure the impact resistance of the PDC cutters.
