Product Description
|
Tricone rock bit IADC417 6″(152.4mm) The 417 tci bits are used to drill low compressive strength,very soft formations .TCI bits maximize the use of bothconical and chisel tungsten carbide inserts of large diameters and high projection.This cutting sstructure design,combined with maximum cone offset,results in high bit penetration rates .The deep intermesh of cutter rows prevents bit bailing in sticky formations.Normal WOB KN/mm (bit dia): 0.35~0.90 RPM:140~70 r/min |
