This type of bit has several cones covered by steel or Tungsten Carbide teeth. Roller cone bits are made up of three equal sized cone and three identical legs which are attached together with a pin connection. Two popular types of these bits are MILLED TOOTH BITS and INSERT BITS.
Milled tooth bit: the cuttings structure is milled from the steel making up the cones. Insert bits: the cutting structure is a series of inserts pressed into the cones IADC code for tri-cone bits Tri-cone bits are named according to IADC code which consists of 3 digits and one letter. The Tricone bits are primarily used for drilling into varied formations ranging from soft, medium to hard. They are especially well suited for hard rock formation. These bits are very reliable in a changing rock conditions. Tricone bits are ideally used for water bore drilling, geo thermal drilling and oil and gas exploration. These bits essentially consist of 3 roller cones having steel teeth or tungsten carbide inserts. As the drill string is rotated the bit cones roll along the bottom of the bore hole in a circular motion. As they roll, new teeth come in contact with the bottom of the hole which helps to chip away the rock formation below and around the bit tooth. Typically air or drilling fluid is used to lift the crushed rock chips from the bottom of the hole up the annulus. Rocksmith offers heavy duty tricone bits to meet your customized drilling needs. We have classified the bits based on their diameter (footprint), american petroleum industry number (API Number) and international association of drilling contractor number (IADC number). The IADC number further classifies the tricone bits based on the tooth material of construction, suitability for drilling into soft, medium or hard rock and bearing type used. Rocksmith can offer tricone bits for all possible combinations of IADC number. To further ease the selection process Rocksmith has further segregated the product catalogues based on the available sizes of steel milled teeth and the tungsten carbide inserts tricone bits.
