Introduction
Cone reamer is a common drilling tool in rock excavation. Cone
reamer is suitable for various types of trenchless drilling rig and
can be used for reaming construction of various rock strata in our
company. The specification covers Φ 10 - 70 inch.
Advantages
Best price and high quality
Bearing type: 1. Sealed and unsealed bearings. 2. Metal seal
journal bearing. 3. Rubber seal journal bearing
Cutting structure: the rear cone and tooth surface are hardened,
which improves the steel tooth profile and welding material, and
the tooth surface protrudes higher
Application: Suitable for horizontal directional drilling in rock
formation reaming drilling
Our products and services have passed the ISO 9001:2008 and API
certification, and the mature production technology ensures that

tungsten carbide blade with new technology. The pilot bit is a tri
cone bit.
Sealing and lubrication
High performance hydrogenated nitrile rubber O-ring and high-grade
grease for bearing sealing.
Used in
It is suitable for Horizontal directional drilling, hard with high
compressive strength and high drillability, such as granite.
