There are various types of TC Core Bits offered by us that are made by tungsten carbide cutters and steel under forging process. These are suitable for soft to hard rock formations and widely used in sample coring of geological drilling. TC bits, like diamond drill bits, drills for cores but use tungsten carbide as its cutting medium. It can cuts the same size core as that by a diamond bit & fits into the same size core barrel. They are used for drilling round holes in steel, non-ferrous metals and other high-density materials. The TC Core Bits are very efficient.
