Description

Introduction We are the first manufacturer of special-shaped diamond enhanced insert in China, can made by your different requirements. The manufacturing principle is same as that of ordinary PDC. But the shape of diamond layer is different for different application. Spherical insert (JFQ series), conical insert (JFZ series), wedge insert (JFX series), eccentric wedge insert (JFBX series), flat insert (JFP series) are available. 1. Spherical insert (JFQ series) Mainly for roller bit for petroleum drilling, can also for small and medium-sized button bit, DTH bit. With good wear ability and better impact toughness, it can be for percussion drilling.
