Coal drilling bit use PDC cutter

ZM diamond PDC cutters  

PDC(polycrystaline diamond compact) drill bits is a new product after the hot-pressed and electroplated drill bit recent years.With special hith-frequency weldin techniques.PDC of high wear resistant to the body as cutting edges.PDC bits are mainly used for geological prospecting,coal exploration,water conservancy and power engineering,etc.
