2"-18" 3/ 4/ 5/ 6 Wings PDC Drag Bits For Water Wells Mining Geothermal
Introduction of PDC drag bits:
PDC drill bit is super hard material combined with diamond and hard alloy under high temperature. It not only has the advantages of hard and durable from diamond, but also has the advantages of high impact resistance and big blade from hard alloy. It greatly improve the drilling efficiency and is the ideal drill bit for the drill operation of medium &hard as well as super hard rock.
The carrier of PDC bits is forged and pressed by first -class
steel. Its mechanical capacity is strengthen by fully automatic
vacuum heat treatment equipment.
The ordinary type adopts Chinese PDC as its blade, while the
super-strong type adopts American blade by GE. Choosing proper type
makes high ratio of performance and price.
Our PDC drill bits are widely used in all industries, such as coal
mining, oil exploration, geological exploration, water and
hydroelectric, railway and road, tunneling construction and so on.
