These iadc 517 tricone bit for well drilling are designed for maximum penetration rates. Bit tracking is virtually eliminated by combining a large cone offset, sharp chisel-shaped inserts and non-uniform tooth spacing. Shirttail protection along with carbide leg protection increases bit life for HDD applications.Tricone Rock Bits iadc 537 provide outstanding performance along with reliability and simplicity. Please follow the guidelines listed below to choose the correct IADC number for our bit. IADC Code Reference Numbers. 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 roller bit for oil drilling
