This system of roller cone identification was established in 1987 and expanded in 1992 to include more features.The first digit represents the hardness of rock formation the drilling tool buttons are suited forEvery drill bit is designed for a certain type of rock formation, ranked according to hardness.The tool is assigned a numbe



    An eight point dull grading system has been established by the IADC to enable drillers and bit manufacturers evaluate the performance of a drill bit. This eight point system is described below and is used on both tricones and fixed cutter bits:1. Inner Cutting Structure - Inner cutting structure wear is also noted by a number ranging from 0 to 8 with 0 being no wear and 8 being total wear.2. Outer Cutting Structure - Outer cutting structure wear is also denoted by a number ranging from 0 to 8 wi

    PDC drill bits, or fixed cutters, come in either matrix or steel body. One might ask, What is the difference? and Which one do I need?Matrix body fixed cuttersare made from tungsten carbide material. This provides improved wear resistance and erosion.Additionally, they are typically more heavy set as far as cutter count.In applications of high fluid volume or high sand,matrix body bits offer longer life and multiple bit runs.Steel body fixed cuttersare made from a high alloy steel. These bits ca
