Cutting Structure
Unique steel tooth structure effectively improving the wearing
resistance of the
teeth and greatly increasing the rate of penetration.
Gauge Structure
Enhanced gauge protection with hard facing on the shirttail,
strength enabled
with special insert tungsten carbide.
Bearing Structure
High precision journal bearing, hard-faced bearing surface. Cone
bearing inlaid
with friction-reducing alloy and then silver-plated, made the
rotating more
stable, safe, and durable.
Seal and Lubrication
The patented unique metal seal can enhance the seal performance, it
has longer
durability than the rubber seal. The compensation bearing grease
system greatly
increases the lubricating reliability and improve the bearing life
effectively.
Application:
Soft formations with low compressive strength,such as shale/clay/
sand stone/
soft limestone/ halite/anhydrite.etc.
We supply different sizes of this type of bit as clients’requirement.
