coal-cutter pick

One of the cutting points attached to a cutter chain for making a groove in a coal seam. The picks are made from quality carbon steel or a hard alloy steel and tipped with fused tungsten carbide, sintered tungsten carbide, or other hard-wearing material. The advent of the coal-cutter pick tipped with tungsten carbide on a heat-treated, alloy-steel shank has resulted in marked improvements in drilling and a reduction in cutting delays.
