Rock Reamer Bits With Replaceable Roller Cone Bit


Overview of Rock Reamer Hole Opener
The rock reamer hole opener produced by Cangzhou Great Drill Bits Co.,Ltd. is
used to expand the diameter of the pilot hole and is mainly used for horizontal
directional drilling of oil, natural gas, electric power, and other pipelines.
The Rock reamer is designed for reaming a variety of rock formations in the
ground. The cone part is made up of a milling cutter for soft formations and a
carbide insert with hard formation for different formations.

The cutting teeth of the cone use TCI cutters or Steel tooth cutters. And the
teeth have good wear resistance and the speed of the drill is fast. Intensive
palm tip welding and full palm back protection, the cones are divided into back
dimension and the diameter is protected by a protective design to effectively
enhance the resistance of the drill bits for rock and concrete.

Apply wear-resistant alloy or carbide tooth on the front stiffener or block
surface. In order to reduce the weight of the rock reamer hole opener without
affecting the support strength, the front centralization plate adopts a hollow
design.

GREAT hole opener uses a sealed high-energy rolling bearing system processed
and assembled at an extremely strict tolerance.

Each reamer has a sealed automatic compensation lubrication system that
balances the internal and external pressure of the bearing and protects the
bearing and sealing system.
