HDD Drilling
What is an HDD Rock Reamer?
Rock reaming bits are used in horizontal directional drilling crossing projects. They are suitable for strata such as strongly, moderately and slightly weathered rocks and gravels, such as granite, gneiss, sandstone, limestone and shale. They feature impact resistance, rock abrasion resistance and long service life.
Conventional structure of rock reaming bit
The precise coordination of the unique angle of the cone bit single piece and the angle of the core shaft enhances the coaxiality of the rock reaming bit.
The multi-layer and multi-pass welding process reduces thermal damage and enhances the tensile strength of the reaming tool.
The robot welding technology has enhanced the stability of the overall quality of the reaming tool.
| The size of the reamer（mm） | mandrel（φ/mm） | guiding（φ/mm） | Single-chip model |
|---|---|---|---|
| 200 - 1800 | 54 - 203 | 200 - 1700 | 437 - 637 |
