PDC reamer (Polycrystalline Diamond Compact reamer) is a high-efficiency trenchless tool for horizontal directional drilling (HDD), used to enlarge pilot boreholes for pipeline installation without surface excavation. It has fixed PDC cutters, widely applied in urban utility, oil/gas and river-crossing projects.
Its key parts include super-hard PDC cutters, a one-piece solid steel body (low failure risk) and hydraulic ports (for cuttings removal and cooling). It works by rotating to enlarge pilot holes to target diameter after pilot drilling.
- High efficiency: 30–60% faster than traditional reamers, saving project time.
- Long service life: PDC cutters resist abrasion, reducing tool replacement.
- Eco-friendly: No surface excavation, suitable for urban areas.
- Cost-effective: Lower operating cost via reduced rig time and labor.
Typical applications: Urban pipeline laying, river/road crossing HDD projects. News example: A new PDC reamer cut construction time by 40% in a city water pipeline project, avoiding road closures.
