Product Description
IADC 547 Roller cones for piling/rotary drilling /trenchless drilling/reaming/hole opening
• IADC CODE 437, 517, 537, 547,617, 627, 637
• The composite sealing structure for the joumal bearing better fit to different drillmg conditions.
• dded special wedge gauge cutters resist abrasion of the tooth edge, thus effectively improve the gauging abilityof the bit.
• Strengthened tungsten carbide teeth on the whole paIm avoid excessive abrasion by rock mass in horizontal drilling process.
• To solve the problem that the palm tip easy to be weared in the trenchless process, we overlay weld hardfacing materials to provide better protection, thus reducing exposure and damage of the bearing due to premature wear of the palm tip.
For HDD/trenchless drilling/reaming/hole opening:
For Rotaty drilling/piling:
