 Product information

 

   Good function hole opener Manufacturer

 

 

Tricone bit Cutting structure: very long widely spaced ,chisel-shaped inserts and considerable cone axis offset against center line of bit ensure very high penetration rate .To secure the bit from diameter loss, the gage protection inserts have got shorter length and greater angle of the top. Formations: long intervals of very soft poorly compacted shales ,sandstone, clays, salts and soft li mestones. Size and IADC available: 3 3/4" to 26" IA415,435,445,417,437,517,537,617

 

The 437 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 structure design,combined with maximum cone offset,results in high bit penetration rates .The deep intermesh of cutter rows prevents bit bailing in sticky formations.
