Mammoth Tricone Bits are excellent bits for rotary drilling with a range of bits to choose from. The Tricone bits are separated in two major categories: Steel Tooth products and Tungsten Carbide products. Steel Tooth (milled tooth) products consist of cutting elements that have been made from the cone. The cutting elements and steel teeth are available in a variety of shapes, sizes and grades of tungsten carbide material. This variety of cutting elements is ideal for a wide spectrum of drilling conditions.
