Abstract

Abstract

Flying dragon" ϕ40 and ϕ42-4P1C insert and button complex type bits have developed the strong points and avoided the weak points of traditional ones bits. When they are used with new G308, YJ2.1R cemented carbide for rock drilling tools with extreme toughness, their service life is three times as much as that of the chisel bits set YG11C insert now used widely in China. At the same time, they maintain remarkable characteristics of high drilling speed and low consumption and will be likely to replace other bits.
