Horizontal Directional Drilling
Horizontal Directional Drilling (HDD) is a trenchless method of installing underground utilities such as pipelines, conduits and cables with minimal surface disturbance. The process has three stages: pilot hole drilling, hole enlargement (reaming) and product pipe installation (pullback). HDD allows for precise steering along a predetermined underground path making it ideal for crossing roads, rivers, railways and other obstacles. Key benefits of HDD are directional control, minimal environmental impact, cost effective in congested areas and reduced restoration compared to open trench methods. It is used in oil and gas, telecommunications, power and water industries.

Over Bit Reamers
Over Bit Reamers are specialized tools used in horizontal directional drilling (HDD) to enlarge the borehole after the pilot hole has been drilled. They fit over the pilot bit or housing and allow for immediate transition from drilling to reaming without having to remove the drill head. This design saves time by combining steering and reaming in one pass.
Key features of over bit reamers:
- No tool changes required
- Compact for tight or shallow job sites
- Durable and cuts in clay, sand and loam
- Less wear on drill components with smoother load transitions
- For short to medium length bores where speed and productivity matter
- These are great for utility installs where downtime is minimal and directional control is key.
