Insert Tooth Roller Bearing Tricone Bit

Insert Tooth Roller Bearing Tricone Bit

Product description:

Air Cooling Roller Bearing Bit

Cutting Structure

The durability of premium tungsten carbide insert is improved with new formulas and new techniques and new techniques.

Gauge Structure

Gauge protection with gauge inserts on the gauge surface of the cone, tungsten carbide inserts and hardfacing on the shirttail increases gauge holding capability.

Bearing Structure

Air cooling roller bearing package. Balls lock the cone, which reduces the probability of cone-dropping to minimum.

Main Type Available

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. Size andIADC available: 2 7/8 to 26 IADC 114 117 216 217 317 321 417437 517 537 617 637 and so on.
