Elliott Cutters
1 / 5
PDC (Polycrystalline Diamond Compact) Cutter is a type of superhard material that compacts polycrystalline diamond with a tungsten carbide substrate at ultra-high temperature and pressure.
Since PDC Cutters consist of diamond grit and a tungsten carbide substrate, they combine the advantages of both diamond and tungsten carbide, featuring:
Currently, PDC Cutters are widely applied to oil field drilling, gas and geological exploration, coal mining, and many other drilling and milling applications. They are used in tooling such as Steel PDC Drill Bits, Matrix PDC Drill Bits for oil drilling, and Tri-cone PDC Drill Bits for coal mining.

Coal Mining: These tungsten carbide button bits are mainly used for coal mining, cutting picks, electric drill bits, and roadway excavation. They are suitable for rotary drilling for pile holes and pavement milling.
Construction: Used for bridge pile foundation excavation, tunnel shielding, high-speed railways, and highway maintenance. These products offer stable and reliable quality for complex applications.
Oil-field: Applied in tri-cone drill bits for oil and gas field excavation. They ensure safety and reliability in deep mining operations, including horizontal directional drilling (HDD).
General Mining: Suitable for high and low-pressure DTH drills and hydraulic screw-in drills. Excellent for hot insert or cold pressing bit processes.
