The Nemo V2 Underwater Angle Grinder is the first cordless, fully submersible angle grinder built for professional underwater use. Designed for commercial divers, underwater welders, and marine maintenance crews, this grinder delivers powerful brushless motor performance at depths up to 164’. Whether cutting rebar in saltwater or polishing tile below the waterline, it’s engineered to withstand harsh environments with military-grade construction, saltwater-resistant coating, and dual high-capacity batteries. The included underwater battery-swapping system eliminates the need to surface until the job’s done.
