16  inch is a regular size in water well drilling, it is working well with small capacity drilling rigs and widely used in the world.

 

Steel tooth tricone rock bit is also named milled tooth tricone rock bit could drill soft mudstone, even soft limestone, the cones are hard faced by tungsten carbide, the bearing is journal and locked by ball, high grade elastomer(rubber)-HNBR O-ring sealed bearing, grease compensating system lubricate the bearing , the working life is very long.
