Natural Diamond Core Bit , Medium to hard formation coring , Multiple blade profile design
FNC series
Natural diamond core bit
* Medium to hard formation coring
Premium natural diamond grains layout makes the bit competent in high compressive medium hard to hard formation with thin interbedded layers.
* Multiple blade profile design
Multiple blade profile design, including round, double taper and parabolic shape, makes the bit suitable foe virous types of medium hard to hard formations.
