Thermal stable polycrystallining core bit

 

Medium hard to hard formation coring
Special thermally-stable polycrystalline diamond cutter layout makes the bit competent in medium hard to hard formation coring operation.

 

Multiple blade profile design

Multiple blade profile design, including round, double taper and parabolic shape, makes the bit suitable for virous types of medium hard to hard formations.

 

Cooling and cleaning system
Various ID flow path designs provide sufficient cooling and cleaning to the whole bit surface.
