Tricone bit Cuttingstructure: very long widely spaced , chisel-shaped inserts and considerable coneaxis offset against center line of bit ensure very high penetration rate . Tosecure the bit from diameter loss, the gage protection inserts have got shorterlength and greater angle of the top. Formations: long intervals of very softpoorly compacted shale, sandstone, clays, salts and soft mestones.
