(φ 300mm - φ 1800mm)
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.

We also suggest that while using this kind of hole opener, the customers can use barrel Reamer to stabilize the bore diameter.

• The rock reamer adopts high quality front and back centralizers, it is well designed and features better performance in centralizing, abrasion reduction and sand return.
• Designed with safety device, effectively preventing drill bits falling accident.
• We are able to provide various hole openers to match with specific layers and boreholes.
• The roller cone is sealed with metal, featuring better abrasion-resistance and ensuring the roller cone longer service life.
• The rock reamer is in cone shape, convenient for pumping back work.

(φ200 - φ1800)
Beast reamer, also called OGRE reamer,is perfect for drilling work covering pebble, shale, river sand, glacial till and also hard layer drilling.

Material: Cast steel

• Maximum mixture
• It is designed with an angular water way, which can keep the carbide steel cutter clean and away from debris and mud. The deep spiral flute is able to bring the cutting particles away effectively, ensuring longer service life of the rock reamer.

(φ200 - φ1800)
Perfect for drilling covering quick sand, sandy soil or medium hard layer drilling

Material: Cast steel

• Enlarging the bore diameter step by step
• Spiral flute of the fluted reamer helps mud and cutting things passing through quickly and achieves a quick penetration rate of the hole opener.

(φ114 - φ1800)
Suitable for relatively hard layer

• Open-design of the hole opener helps it to penetrate through some stones
• The reamer features welded bit angles for especially rough rock formations
• The reamer bits are designed in order for efficient penetration rate of the rock reamer

(φ150 - φ1800)
Barrel reamer is suitable for normal rock formation.

• The barrel reamer features smooth surface as compared with the other hole openers, and it also has cutters.
• The welded cutters with angles can be used for especially rough rock formations.
• Reducing effect of loose stones and cutting things on the bore diameter, making it easy for hole drilling and being available for efficient pipe extraction.

We also supply different styles reamers, like Black Widow, Warthog Reamer for diversify rock formation to satisfied consumers'need.
