Specifications
| Reamer Type | Best For | How It Works | Key Advantage |
|---|---|---|---|
| Fluted Reamer | Soft soils (sand, silt, soft clay) | Large fluid ports and grooves (flutes) mix soil into a slurry for easy removal. | Excellent for mixing and creating a clean borehole. |
| Blade/Wing Cutter | Sticky clay | Sharp blades slice through cohesive soils without getting clogged up. | Very aggressive and fast in the right conditions. |
| Carbide Tooth | Medium to hard soils, gravel, cobble, soft rock | Hardened, wear-resistant teeth grind and chip away at tougher material. | Versatile and durable for mixed ground conditions. |
| PDC or TCI | Hard, solid rock | Extremely hard cutters (PDC) or inserts (TCI) shear the rock face. | The only effective option for drilling in solid rock formations. |

Application
Horizontal Directional Drilling (HDD) is a trenchless method for installing underground pipelines, conduits, and cables without the need for extensive open-cut excavation. This technique involves drilling a precisely controlled pilot hole along a predetermined bore path, often navigating under obstacles like roads, rivers, or existing infrastructure.
After the pilot hole is complete, reaming tools are used to enlarge the bore to the desired diameter, and then the utility pipe is pulled through the enlarged hole. HDD minimizes surface disruption, reduces environmental impact, and offers a cost-effective solution for a wide range of underground utility installations.
Tools Needed:
- Drill rig
- Drill pipe
- Drill bit
- Mud mixing system
- Locator and tracking equipment
- Reaming tools
