TCI 437 softformation tci tricone bits

The 437 tci bitsare used to drill low compressive strength very soft formation tci bitsmaximize the use of bothconical and chisel tungsten carbide inserts of largediameters and high projection. This cutting structure design combined withmaximum cone offset , results in high bit penetration rates. the deep intermeshof cutter rows prevents bit bailing in sticky formations.
