• Tungsten carbide cutter of high strength and toughness is used to increase the impact
resistanceof cutters and decrease the breakage rate.
• Optimal cutter rows,cutter quantitty,cutter length and cutter structure design largely
improve the drilling capability and speed.
• Widely used in oil exploration, mining prospecting,subterranean beat,hydrology etc.
