17 1/2 IADC 637 Well Used Good function hole opener Manufacturer
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 637 bits can be used to drill hard and abrasive formations .Wearresistant tungsten carbide inserts are used in the outer rows to prevent loss of bit gauge.Maximum numbers of bemisphericalshaped inserts are used in all rows to provide cutter durability and long life.
