Features
Cutting Structure
The reamer mainly consists of four or more cones. Cutting Structure
with premium tungsten carbide hardfacing or premium tungsten
carbide insert of formulas and new techniques is utilized, and
increases wear-resistance capability of reamer. The pilot is three
cone bit.
Seal and Lubrication
High performance HNBR O-ring for bearing seal and advanced grease
for lubrication.
Advantages
Most favourable price and high quality
Bearing type: 1. Sealed bearing and non-sealed bearing. 2. Metal
sealed journal bearing. 3. rubber sealed journal bearing
cutting structure: The back cone and the teeth all surface is are
hardfaced strengthening, improved steel tooth shape and welding
materials,showing teeth higher
Application formation: Soft with low compressive strength and high
drillability, such as shale, clay, salt bed and etc
