It depends on the hardness and abrasiveness of the formation.
Soft formations (e.g., clay, sandstone): Use IADC 3 series – softer teeth, higher RPM.
Medium formations (e.g., limestone, shale): Use IADC 5-6 series – wear-resistant alloy teeth, strong pressure resistance.
Hard formations (e.g., granite, quartzite): Use IADC 7-8 series – reinforced teeth, high impact resistance.
YLifespan depends on drilling conditions and maintenance.
Under normal use, a Tricone Bit can drill
several thousand meters
. Hard formations, high RPM, or poor lubrication can cause faster wear.
Regularly check bearings and clean nozzles to extend life.ey are specifically designed to drill through hard rock formations.
Follow the recommended weight on bit (WOB) and RPM for efficiency.
Soft formations:
0.3-0.8 KN/mm
150-70 RPM
Medium formations:
0.35-1.05 KN/mm
120-50 RPM
Hard formations:
0.7-1.2 KN/mm
70-40 RPM
Avoid using maximum WOB and RPM at the same time to reduce damage.
Watch for these signs of wear：
Teeth are dull, broken, or excessively worn
Bearing failure (heat, abnormal movement)
Drilling speed drops significantly
Replacing the bit on time prevents damage to the drill string and improves
efficiency.
Proper storage and maintenance extend lifespan.
Clean the bit
after each use to remove debris.
Apply lubricant
to the bearings to prevent rust.
Store in a dry place
away from moisture and extreme temperatures.
Inspect before use
for any cracks, loose cones, or worn teeth.
