12 1/2" IADC 537 rock roller bit drill bit

1.TCI Tricone drill bit

1>Soft formation TCI Tricone drill bit

         The soft formation TCI tricone drill bit are used to drill low compressive strength,very soft formations.

This bit maximized to use both  conical and chisel tungsten carbid insters of large diameters and high projection.

This cutting structure design combined with maximum cone offset ,result in high bit  penetration rates ,The deep i

ntermesh of cutter rows prevents bit bailing in sticky formations. tricone drill bit

2>Medium hard formation TCI trcone drill bit

        The meduim formation TCI tricone drill bit features aggresive chisel tungsten carbid insters on the heel rows

and inner rows .This design provides a fast drilling rate and added cuttering structure durability in medium and

medium hard formations.The rubber O-ring provide adequate sealing for bearing durability. tricone drill bit

3>Hard formation TCI tricone drill bit

       The har formation TCI tricone drill bits can be used to drill hard and abbredive formations.Wear resistence

tungsten carbid insters are used in the outer rows to prevent loss bit gauge.Maximm numbers of hemispherical

shaped insterts are used in all rows to provide cutter durability and long life. tricone drill bit
