The working principle of HDD Fluted Reamers is based on fluid dynamics. Under pressure, the fluid is expelled and forms a high-speed rotating vortex, which generates centrifugal force accompanied by axial thrust.
This power pushes the drill bit at the top of the reamer cone into the formation, thereby achieving the reaming operation.

Our winged reamers are known for their swift drilling capabilities. They combine a low mass, open body with a double slope wing design for exceptional toughness to deliver efficient cutting and mixing actions.
The wing-like extensions create a powerful vortex effect, expediting the removal of cuttings and reducing the risk of clogging. This action allows for faster drilling speeds, saving you valuable time on your projects. The result is more work with less wear and tear on your drill and drill string.

Rock hole opener is a tool designed for drilling hard rock formations. The roller cone of it can be customized in diversified sizes and styles and as an important part of rock hole opener, the roller cone ensures high efficiency and excellent performance of the rock hole opener.
To achieve better performance in penetration rate,cutting ability and low torque of the reamer, we grind the alloy into powder and embed it in the roller cone while making the roller cone.
