Rock Hole Opener

(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.

Features
  • 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.

Material: Cast steel

Features
  • 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.
Fluted Reamer

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

Material: Cast steel

Features
  • 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.
