Hydro Drilling and Excavation

Small nozzles with 1/8” NPT threads are typically used for this application, and require special spray patterns with multiple forward jets ranging from 0° to 25°. Aqua Mole’s Button Nose nozzles are ideal for this application, and our custom drilling service means that special patterns can be provided with no delay or extra costs. Aqua Mole’s quantity discount program can reduce costs on large jobs where many nozzles are often consumed.


At Aqua Mole, your pump’s pressure and flow specifications are  computer modeled to determine the optimum orifice size for your selected spray pattern. Get the most out of your equipment with Aqua Mole’s custom orifice drilling.

Rear jet angles are possible ranging from 25° to 70° in the groove. It’s possible to drill 90° side jets in the knurled area in the nose section. Forward jets can be drilled from 0° (straight ahead) up to 45°.
